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.

Abstract Searching for Anderson localization of light in three dimensions has challenged experimental and theoretical research for the last decades. Here the problem is analyzed through large scale numerical simulations, using a radiative Hamiltonian i.e. a non-Hermitian long-range hopping Hamiltonian, well suited to model light-matter interaction in cold atomic clouds. Light interaction in atomic clouds is considered in presence of positional and diagonal disorder. Due to the interplay of disorder and cooperative effects (sub- and super-radiance) a novel type of localization transition is shown to emerge, differing in several aspects from standard localization transitions which occur along the real energy axis. The localization transition discussed here is characterized by a mobility edge along the imaginary energy axis of the eigenvalues which is mostly independent from the real energy value of the eigenmodes. Differently from usual mobility edges it separates extended states from hybrid localized states and it manifest itself in the large moments of the participation ratio of the eigenstates. Our prediction of a mobility edge in the imaginary axis, i.e. depending on the eigenmode lifetime, paves the way to achieve control both in the time and space domain of open quantum systems.

Abstract We consider N run-and-tumble particles in one dimension interacting via a linear 1D Coulomb potential, an active version of the rank diffusion problem. It was solved previously for N=2 leading to a stationary bound state in the attractive case. Here the evolution of the density fields is obtained in the large N limit in terms of two coupled Burger’s type equations. In the attractive case the exact stationary solution describes a non-trivial N-particle bound state, which exhibits transitions between a phase where the density is smooth with infinite support, a phase where the density has finite support and exhibits ”shocks”, i.e. clusters of particles, at the edges, and a fully clustered phase. In presence of an additional linear potential, the phase diagram, obtained for either sign of the interaction, is even richer, with additional partially expanding phases, with or without shocks. Finally, a general self-consistent method is introduced to treat more general interactions. The predictions are tested through numerical simulations.
摘要 我们考虑了一维中通过线性一维库仑势相互作用的 N 个奔跑和翻滚粒子，这是等级扩散问题的主动版本。该问题曾在 N=2 的情况下求解，并得出了吸引力情况下的静止束缚态。在这里，密度场的演化是通过两个耦合伯格方程在大 N 极限得到的。在有吸引力的情况下，精确的静态解描述了一个非三维的 N 粒子束缚态，该束缚态在以下三个阶段之间发生转变：密度为无限支撑的平滑阶段；密度为有限支撑并在边缘表现出 "冲击"（即粒子群）的阶段；以及完全成团的阶段。在存在额外线性势的情况下，在相互作用的任一符号下得到的相图甚至更加丰富，有额外的部分膨胀相，有或没有冲击。最后，引入了一种一般自洽方法来处理更一般的相互作用。预测结果通过数值模拟进行了检验。

Abstract The aim of this short review is to summarize the developing theory aimed at describing the effect of plastic events in amorphous solids on its emergent mechanics. Experiments and simulations present anomalous mechanical response of amorphous solids where quadrupolar plastic events collectively induce distributed dipoles that are analogous to dislocations in crystalline solids. The novel theory is described, and a number of pertinent examples are provided, including the comparison of theoretical prediction to simulations or experiments.
