We introduce a general method to determine the large-scale non-equilibrium steady-state properties of one-dimensional multi-species driven diffusive systems with open boundaries, generalizing thus the max-min current principle known for systems with a single type of particles. This method is based on the solution of the Riemann problem of the associated system of conservation laws. We demonstrate that the effective density of a reservoir depends not only on the corresponding boundary hopping rates but also on the dynamics of the entire system, emphasizing the interplay between bulk and reservoirs. We highlight the role of Riemann variables in establishing the phase diagram of such systems. We apply our method to three models of multi-species interacting particle systems and compare the theoretical predictions with numerical simulations.

Existing optimized random phase (ORAP) approach mainly faces the limitations of fixed supports. Different ORAPs need to be generated for different target images with different support sizes, thus lacking flexibility and severely limiting applicability. This paper proposes a support-free optimized Fourier random phase (SF-OFRAP) approach for non-iterative kinoform generation, which greatly improves the speed and flexibility of generating kinoforms, and can achieve comparable performance to the ORAP approach. The proposed SF-OFRAP approach not only breaks the fixed support constraint of a target image, but can generate kinoforms of target images with different shapes, different positions, etc. with arbitrary supports. Our proposed SF-OFRAP approach can achieve real-time generation of kinoforms for multi-view holographic display using only a single generated SF-OFRAP without the need for additional phase compensation. The SF-OFRAP approach is suitable for real-time holographic display. Experiments verified the superiority of the produced SF-OFRAP over the ORAP method in terms of flexibility and adaptability to multiple different objects in different positions and different shapes using only one kind of these. The experimental results verify the effectiveness and excellent flexibility of SF-OFRAP for video holographic display and multi-view holographic display.

We examine the role of quantum measurement and coherence, considering the shell game with a quantum particle. The game consists of three sites arranged to form a ring geometry and a particle visiting the sites through a unitary evolution. A player selects one of the sites as a target site and wins if the target site contains the particle at a preassigned time. The player has two options for determining win or loss: local and global measurements, which perform projective measurements on the occupancy of the target site and the particle's position, respectively. The game can be played over multiple rounds, and each round begins with the state reached at the end of the previous round. We calculate the probability of winning at each round and the probability of consecutive losses and find that those probabilities have characteristic asymptotes. We obtain the analytic expressions of the asymptote and scrutinize their essential dependence on the measurement options and coherence in the initial ensemble.

Abstract We demonstrate the occurrence of oscillatory reactions in the ultra-cold chemistry of atom-molecular Bose-Einstein condensate. Nonlinear oscillations in the mean-field dynamics occur for a specific range of elliptic modulus, giving rise to both in- and out-phase modulations in the atom-molecule population density. The reaction front velocity is found to be controlled by photoassociation, which also regulates the condensate density. Two distinct pair of in-phase bright localized gap solitons are found as exact solutions, existence of one of which necessarily requires a background. Cnoidal atomic density-waves along with a plane wave molecular motion are observed in both attractive and repulsive domains. Role of intra- and inter-species interactions on both existence and stability is explicated in the presence of photoassociation.

Abstract Core-periphery structure is commonly observed in diverse real-world networks, where nodes are categorized as core or peripheral nodes by connection patterns. It plays an important role in ensuring potential functionality and intrinsic order in networks. Networks are inevitably suffering from the malicious attacks and random errors, which could lead to the collapse of core-periphery structure, and in turn the performance degradation and even the total instability of network behaviors. Therefore, it is of great significance to rapidly recover such structure after destruction. However, few of the existing work about network have laid emphasis on core-periphery restoration. Here we propose a novel recovery index to characterize and measure the quality for the core-periphery restoration when a disaster happens. Several efficient algorithms guided by our index are devised to provide optimal or near-optimal restoration plans considering both the mesoscale core-periphery structure and global network connectivity. Numerical results are provided to demonstrate the efficacy of our framework that remarkably enhances core-periphery restoration.

Abstract Neurological disorders place a significant burden on patients, their families, and society, posing immense scientific challenges in terms of treatment and mechanistic research. Neuromodulation involves the application of invasive or non-invasive technologies to externally manipulate the nervous system of the brain, aiming to provide excitatory or inhibitory modulation that can improve abnormal neural activity. In the previous studies, neurodynamic analysis methods have not only provided novel tools for the study of neuromodulation techniques, but also provided new modulation strategies for the diagnosis and treatment of neurological diseases. In this paper, we present a brief overview of the current state of dynamic modeling and analysis for various neuromodulation techniques, including electrical, optical, magnetical, and ultrasonic approaches, and discuss the future prospects of modeling and analysis developments in neuromodulation.

Abstract In this work we shall prove that the tensor spectral index of the
primordial tensor perturbations for GW170817-compatible
Einstein-Gauss-Bonnet theories, takes the approximate simplified
form $n_{mathcal{T}}simeq 2left(-1+frac{1}{lambda(phi)}
right)epsilon_1$ at leading order, with $lambda (phi)$ being a
function of the scalar field which depends on the scalar field
potential and the second derivative of the scalar-Gauss-Bonnet
coupling $xi''(phi)$. With our analysis we aim to provide a
definitive criterion for selecting Einstein-Gauss-Bonnet models
that can provide a blue-tilted inflationary phenomenology, by
simply looking at the scalar potential and the scalar-Gauss-Bonnet
coupling. We shall prove this using two distinct approaches and as
we show the tilt of the tensor spectral index is determined by the
values of the potential $V(phi)$ and of scalar-Gauss-Bonnet
coupling at first horizon crossing. Specifically the blue-tilted
tensor spectral index can occur when $xi''(phi_*)V(phi_*)>0$ at
first horizon crossing.

Abstract Relay synchronization, which is the interlayer synchronization of two indirectly connected layers, is an important phenomenon in multiplex networks. In this study, relay synchronization is investigated through a triplex network of Hindmarsh-Rose neurons while considering attractive and repulsive intralayer couplings. Relay synchronization is improved when the remote layers have attractive coupling, and the relay layer has repulsive coupling. The essential conditions for the local stability of relay synchronization is found within the framework of master stability function approach. The analytical results are supported by numerical data on synchronization error. Furthermore, enhanced relay synchronization is also shown for larger networks and different internal couplings. Finally, the generalizability of the outcome is confirmed by investigating a triplex network of R"ossler systems.
摘要 中继同步是两个间接连接层的层间同步，是多路网络中的一个重要现象。本研究通过 Hindmarsh-Rose 神经元的三重网络研究了中继同步问题，同时考虑了吸引性和排斥性层内耦合。当远端层具有吸引力耦合，而中继层具有斥力耦合时，中继同步性会得到改善。在主稳定函数方法的框架内，找到了中继同步局部稳定性的基本条件。同步误差的数值数据为分析结果提供了支持。此外，对于更大的网络和不同的内部耦合，也显示了增强的中继同步性。最后，通过研究 R "ossler 系统的三重网络，证实了结果的通用性。

Abstract In this work we consider a fermionic quantum gas within a Lorentz-Violating background at finite temperature. We derive the effective action within Path Integral formalism considering the interaction of external electromagnetic field and Lorentz violating background fields with quantum fermions. To introduce the temperature effects, we employ the Matsubara formalism. Comments about the corresponding phenomenology are also made.
