In this paper, we presented a simple and robust algorithm for QPE using compressed sensing. For the single eigenvalue estimation (i.e., QPE), we rigorously established its Heisenberg-limit scaling in Theorem 2 and numerically demonstrated its performance compared to other state-of-the-art QPE algorithms in Sec. 4. Our ...
Compressed sensing, in essence, is similar to non-adaptive MM-QCELS. Both methods aim to fit the sampled data using a signal ansatz. However, they differ in sampling strategies and optimization objectives. In MM-QCELS, times are sampled from a continuous probability distribution, and the cost function minimizes the tot...

In discrete sampling protocols, would it be possible to shorten the maximal runtime by biased sampling of times? What is the limitation in the discrete scenario? Can we achieve a similar improvement to the Gaussian filter method in [18]?
In our numerical experiments, the test of another sampling (Algorithm 3) is actually unnecessary. Is it possible to show this analytically as well?

We compare the asymptotic computational costs of the density matrix algorithm and the baseline algorithm that utilizes canonicalization, as discussed in Section 3.2.1. In Theorem 6.1, we establish that the density matrix algorithm can be more efficient in approximating a general tensor network as an embedding tree. The...
We will show in Section 6.4 that the cost of the density matrix algorithm is upper-bounded by the canonicalization-based algorithm.
In Algorithm 4, the computation of each density matrix occurs only once. Considering that the embedding tree T𝑇Titalic_T is limited to being a rooted binary tree, there are at most three density matrices to be calculated for each vertex v𝑣vitalic_v in the embedding tree. Below we bound the asymptotic computational co...
Specifically, we show in Section 6.4 that the asymptotic computational cost of the algorithm is upper-bounded by the cost of the canonicalization-based algorithm, and we show in Section 8 that for many input tensor networks, the proposed algorithm substantially reduces the overall execution time.

Fig. 7 examines the effects of the parameter cOsubscript𝑐Oc_{\rm O}italic_c start_POSTSUBSCRIPT roman_O end_POSTSUBSCRIPT on the time-domain profiles.

The analysis of the perturbation potential provides valuable insights into the nature of the QNMs for both scalar and electromagnetic perturbations. The variations in the potential with respect to parameters such as the multipole moment l𝑙litalic_l, the model parameter α𝛼\alphaitalic_α, the coupling parameter cOsubsc...
The charge parameter Q𝑄Qitalic_Q has a significant and nonlinear impact on the QNM spectrum of black holes. As shown in Figs. 13 and 14, both the oscillation frequency (real part of QNMs) and the damping rate (imaginary part of QNMs) increase as Q𝑄Qitalic_Q increases. This behavior holds true for both scalar and elec...
Finally, in Fig. 8, the time-domain profiles are plotted with varying values of the charge parameter Q𝑄Qitalic_Q. The results indicate that the black hole charge has a noticeable effect on the oscillation frequency for both scalar and electromagnetic perturbations. As Q𝑄Qitalic_Q increases, the oscillation frequencie...
Physically, the increase in oscillation frequency with higher Q𝑄Qitalic_Q can be understood in the context of the black hole’s enhanced electric field. As the black hole’s charge increases, the strength of its electromagnetic field grows, which leads to more tightly bound perturbations. This results in higher frequenc...

In addition, a number of potential improvement may be anticipated. The usage of permutations on the residual indices in step (vi) in Subsection II.3 is a posterior collection. It may be feasible to be performed as a prior with the step (iiid) of using linear combinations of excitation operators. That would lead to a si...
In the present work, we reported the further formulations for the linear combinations of the projection manifolds, the hash-table canonicalization algorithm, and the numerical results for the previous general-order open-shell CC method based on the PSA scheme wang2024general .

We further notice the differences between PSA and spin-orbital CC are mainly at the CCSD levels. For example, in the OH molecule, the difference between the PSA-T[1|2]delimited-[]conditional12[1|2][ 1 | 2 ]R[1|2]delimited-[]conditional12[1|2][ 1 | 2 ]-CCSD and the spin-orbital CCSD is about 6 ×\times× 10-5 a.u., that i...

The number of resulting equations can be large at higher order PSA-CC and spin adaptations. This could slow down the computations.

As for the global momentum dependence of the pseudogap, the ARPES results reported by Matsui et al. Matsui et al. (2005) and Ikeda et al. Ikeda et al. (2009) have indicated the reduction of pseudogap magnitude upon approaching (π𝜋\piitalic_π, 0). This momentum dependence cannot be understood within the simple AFM band...
So far, the pseudogap of the electron-doped cuprates has been observed through the measurements of optical conductivity Onose et al. (2001); Wang et al. (2006), scanning tunneling spectroscopy Zimmers et al. (2007), and ARPES Armitage et al. (2001); Matsui et al. (2005); Park et al. (2007); Matsui et al. (2007); Richar...
One scenario to explain the overall band structure without assuming the long-range AFM order is the nodeless pseudogap proposed by Sakai et al. Sakai et al. (2010, 2013), based on a CDMFT calculation Kotliar et al. (2001) on the Hubbard model. They

However, as highlighted in discussions of entanglement entropy, the AdS/CFT correspondence inherently features nonlocality[9].
Then, the training can be interpreted as a correction due to quantum effects corresponding to nonlocality.
This nonlocality, which arises from quantum mechanical effects, is also expected to permute or spread information beyond the classical distortions of time and space mentioned earlier.
Note that our discussion of nonlocality concerns how quantum effects can spread or mix information in ways that exceed classical correlations.
However, note that nonlocality stemming from quantum effects manifests as the mixing and spreading of information, and it can be partially emulated even within classical CA models.

The time the GAN post-processing takes is negligible in comparison, taking 0.35 seconds per model year on a V100 GPU and 37.17 seconds on a single CPU. The quantile mapping is similarly efficient taking 0.59 seconds per model year on a CPU.
This can be explained by the fact that the precipitation of the future scenario lies well outside the training distribution.
Down-scaling applications that increase the resolution of the ESM could be a direction for future research.
A potential direction for future research could be to develop a stochastic model that directly learns the uncertainties.
taking ERA5 reanalysis data as ground truth. Note that any other, and especially purely observational, precipitation dataset with sufficient temporal resolution could readily be used instead.

When we select the appropriate value of λ𝜆\lambdaitalic_λ to construct the U⁢(r)𝑈𝑟U(r)italic_U ( italic_r ) as shown in Fig. 2(a), there are two local maxima of the effective potential.
Choosing different values of the parameters, we may have from 00 to 3333 local maxima of the effective potential, as shown in the left image of Fig. 5.

To carry out parameter estimation for each event that passes our selection criteria, we use public data [19, 20] from GWTC-1 through GWTC-3. We use lalinference_mcmc [18, 21, 22, 23], which implements Markov chain Monte Carlo (MCMC) with the Metropolis-Hastings algorithm and lalinference_nest, which implements nested s...
Because of these considerations, we conclude that the weighted SVD-assisted random draw method produces constraints that are unreliable and are likely to be underestimates of the true uncertainties in the measurement of SME coefficients. We verify this claim by testing this method against its Bayesian counterparts in a...

Finally, we can compare our numerics with the numerics on spreading of wave packets in the following way.

Instead, we do investigate how much the dynamics at positive temperature and at weak interaction is slowed down by its proximity to a localized system. We will explain later how this connects to an interesting ongoing debate, but first, we introduce the model and set the stage.
We focus here on the dynamics at λ=0𝜆0\lambda=0italic_λ = 0: The chain is harmonic and the system is decomposed into a set of |ΛL|subscriptΛ𝐿|\Lambda_{L}|| roman_Λ start_POSTSUBSCRIPT italic_L end_POSTSUBSCRIPT | independent modes.
The disordered Klein-Gordon chain with a quartic interaction is a prototypical example of an interacting classical many-body system,
The fate of Anderson localization in the presence of genuine many-body interactions, or anharmonicity, is a matter of considerable interest and debate,
It is also important to consider sufficiently generic interactions, see e.g.  [12] for an example of a many-body system that, despite probably being chaotic, exhibits subdiffusive transport.

In this section we work out consequences of the phenomenological Rashba spin-orbit coupling, Eq. (1), for electron-electron interaction Hamiltonian. To this end consider a 3D Rashba system without structure inversion asymmetry. A 2D case is a simple particular case of this consideration, which is briefly mentioned in t...
The notion of pair spin-orbit interactions (PSOI) [31] represents a conceptual shift from these traditional SOI mechanisms. Unlike the single-particle RSOI, which arises from external electric fields, PSOI originates directly from the Coulomb fields of conduction band electrons. Therefore, PSOI does not rely on structu...
Yet, a significant gap persists in reliably estimating the Rashba coupling constant, particularly concerning the response of layered materials to in-plane electric fields.

In Fig. 8, the score for the random acting agents is approximately 00, since the cooperative sequential coin game is a zero-sum game.

As depicted in Fig. 8, a better result is achieved by the VQC approach compared to random. On this basis, we compare the performance of this VQC approach to that of a neural network with a comparable number of parameters.
In our experiments, we showed that our VQC approach performs significantly better compared to a neural network with a similar amount of trainable parameters. Compared to the larger neural network, we can see that the VQC approach achieves similar results, showing the effectiveness of using VQCs in a MAQRL environment. ...
In the previous section, we observed that a neural network with the same number of parameters as the VQC of our approach cannot match the VQC’s performance. We will now compare the results with a neural network that has significantly more parameters. Again, mutation only is used for the evolution of subsequent generati...
Here we exploit the higher expressive power of VQCs compared to conventional neural networks [Chen et al., 2022].

Note that the VQC has 148148148148 parameters (3 * 6...

There are several steps to solving the optimization problem as shown in Fig. 3.

In this paper, we are proposing a turn based model in a 3D lattice for the protein folding problem.

This exercise has to be carried out for all pairs of (i,j)𝑖𝑗(i,j)( italic_i , italic_j ). This will penalize all non-adjacent beads from having equal sets of coordinates.

The previous paper Yahiaoui2018 proposed the EIT from bright-bright modes coupling, which is similar to Fig. 2 (b). However, our CIT is demonstrated in Fig. 2 (c). Note that Fig. 2 (b) and (c) have different polarization. Therefore, in our paper, two dark modes can not be excited by external field without bright mode ...
The CIT dip comes from the interference of dark modes due to asymmetric dark modes. The interference of dark modes can provide the Fano shape in the transmission spectrum, as shown in Fig. 2 (b). Fig. 2 (b) demonstrates the transmission spectrum of dark modes with x-polarized THz wave without bright mode and this confi...

Therefore, the energy of bright mode can not flow to dark modes due to the suppression of dark modes. Consequently, bright mode can excite by external THz wave again, which causes the CIT effect, as shown in the blue, green and red lines of Fig. 2 (c). As we can see from the results, all the maximum frequencies of Fano...
For better understanding, We plot the electric field and current density field at CIT frequency, as shown in fig. 6 with corresponding to around 0.72 THz for the red line in Fig. 2 (c).

Thus, the discrete Price equation pertains to change in a trait after a single generation, whereas the virial theorem is formulated with continuous-time, and is additionally time averaged. H...

Moreover, the eigenspectra of open cavities show both continuous and discrete branches [18, 19] and a non-singular transformation is required so that their topology is preserved [20, 21].

For our quasicrystal, there are five reflection planes (ℛℛ{\cal{R}}caligraphic_R) dividing the system into two mirror-symmetric halves. They bisect the edges of the central decagon at right angles; see Fig. 1(a). The flux associated with the plaquettes intersecting ℛℛ{\cal{R}}caligraphic_R are fixed by property (i). Fo...
The boundary states, on the other hand, are strongly localized along the edges leading to a nearly size-independent IPR. To quantitatively study the relation between the boundary states and the local imbalance, we introduce Δ⁢N=∑regions|NA1−NA2|Δ𝑁subscriptregionssubscript𝑁subscript𝐴1subscript𝑁subscript𝐴2\Delta N=\...
Due to the imbalance (e.g. without any loss of generality, more A1subscript𝐴1A_{1}italic_A start_POSTSUBSCRIPT 1 end_POSTSUBSCRIPT sites compared to A2subscript𝐴2A_{2}italic_A start_POSTSUBSCRIPT 2 end_POSTSUBSCRIPT), the number of rows and columns in G𝐺Gitalic_G are different, leading to some eigenstates with zero ...

The Hamiltonian defined on any finite system reveals an interesting excitation spectrum; see, for instance, Fig. 1(d) for the density of states (DOS) at the isotropic point. While a naive interpretation might lead us to conclude the existence of a gapless phase (with E=0𝐸0E=0italic_E = 0) over a broad range of paramet...

The number N𝑁Nitalic_N of single diodes for Diode A is about 300, and that for Diode B is 7, respectively.
On the other hand, under the negative-illumination, the linear curve moves up due to the photocurrent generation.
The current sources represent photocurrent generation, and the parallel resistances are shunt resistances of the p-n junctions.

Most recently, the 15-year pulsar timing data collected by the North American Nanohertz Observatory for Gravitational Waves (NANOGrav) presented convincing evidence for a low-frequency Gravitational Wave Background (GWB) [11], potentially originating from PBHs [12]. Future space-based GW interferometers like LISA, BBO,...
In the vast landscape of cosmology, inflation emerges as a crucial concept that sheds light on fundamental characteristics of the observable universe at large scales. Inflation explains critical aspects of the universe’s structure, such as its immense size, uniformity, isotropy, and overall geometry. It gives rise to p...
PBHs have been proposed as potential constituents of dark matter, accounting for anywhere from a fraction to the entirety of its abundance. One of the primary mechanisms for PBH formation in the early universe involves the amplification of the primordial curvature perturbation spectrum.
When the perturbation associated with the PBH enters the horizon, the PBH’s mass is dictated by the horizon’s mass. The relationship between the scale of the perturbation and the mass of the PBH during formation is expressed as follows,
The fractional abundance of the primordial black holes as a function of their mass is shown in Fig. 6. We have used the benchmark point parameters of table 3. For only the first two BPs, the PBHs can explain dark matter in totality. The shaded regions correspond to the various observational constraints [95, 96, 17].
