We study a variant of the one-dimensional swarmalator model where the units' interactions have a controllable length scale or range. We tune the model from the long-range regime, which is well studied, into the short-range regime, which is ...
Stable three-dimensional vortex solitons of high topological charge in a Rydberg-dressed Bose-Einstein condensate with spin-orbit coupling [0.03%]
具有自旋轨道耦合的里德堡原子相干驱动玻色爱因斯坦凝聚中高拓扑荷稳定的三维涡旋孤子

Stable vortex solitons (VSs) are objects of great interest for fundamental studies and various applications, including particle trapping, microscopy, data encoding, and matter-wave gyroscopes. However, three-dimensional (3D) VSs with high t...
Confined active particles with spatially dependent Lorentz force: An odd twist to the "best Fokker-Planck approximation" [0.03%]
具有空间依赖洛伦兹力的受限活性颗粒：“最佳福克-普朗克近似”的奇特扭转

We derive a version of the so-called "best Fokker-Planck approximation" (BFPA) to describe the spatial properties of interacting active Ornstein-Uhlenbeck particles in arbitrary spatial dimensions. In doing so, we also take into account the...

We investigate the emergence of sustained spatiotemporal behaviors in reaction-phase separation systems. We focus on binary systems, in which either one or both species can phase separate, and we discuss the stability of the homogeneous sta...
Strain stiffening due to stretching of entangled particles in random packings of granular materials [0.03%]

Stress-strain relations for random packings of entangling chains under triaxial compression can exhibit strain stiffening and sustain stresses several orders-of-magnitude beyond typical granular materials. X-ray tomography reveals the trans...

Echo chamber effects in social networks are generally attributed to the prevalence of interactions among like-minded peers. However, recent evidence has emphasized the role of hostile interactions between opposite-minded groups. We investig...

In this paper we perform a thorough numerical study of structural and spectral properties of hyperbolic random geometric graphs (HRGs) G(n,ρ,α,ζ) by means of a random matrix theory (RMT) approach. HRGs are formed by distributing n nodes ...
Crossover anomalies in frustrated two-dimensional Ising spin system with four-spin interaction [0.03%]

As is well known, one-dimensional spin systems with short-range interactions cannot undergo a phase transition at finite temperature. However, in many 1D Ising spin models with frustration, at a certain crossover point, the thermodynamic qu...
Navigating uncertainty: Risk-averse versus risk-prone strategies in populations facing demographic and environmental stochasticity [0.03%]
在不确定中导航：面对人口和环境随机性的群体中保守与冒险的风险策略

Strategies aimed at reducing the negative effects of long-term uncertainty and risk are common in biology, game theory, and finance, even if they entail a cost in terms of mean benefit. Here, we focus on the single mutant's invasion of a fi...

Conservation laws are of great theoretical and practical interest. We describe an alternative approach to machine learning conservation laws of finite-dimensional dynamical systems using trajectory data. It is a unique approach based on ker...
