While linear stochastic differential equations are exactly solvable, the solutions for nonlinear equations are traditionally sought from the corresponding Fokker-Planck description. Based on the separation of deterministic and stochastic ti...

Motivated by the idea of using simple macroscopic examples to illustrate the physics of complex systems, we modify a historic experimental setup in which interacting floating magnets spontaneously self-assemble into ordered clusters. By mak...
Molecular Stokes-Einstein and Stokes-Einstein-Debye relations for water including viscosity-dependent slip and hydrodynamic radius [0.03%]
考虑粘度依赖滑移和水的水动力学半径的分子斯托克斯-爱因斯坦和斯托克斯-爱因斯坦-德拜关系式

We perform molecular dynamics simulations of liquid water at different temperatures and calculate the water viscosity, the translational and rotational water diffusivities in the laboratory frame as well as in the comoving molecular frame. ...
Mean-field models of neural populations with Gaussian noise and non-Cauchy heterogeneities [0.03%]

We derive mean-field equations for a large population of globally coupled quadratic integrate-and-fire neurons subject to weak Gaussian noise and heterogeneous time-independent non-Cauchy distributed currents. We employ a circular cumulant ...
Thermodynamics and criticality of supersymmetric spin chains of Haldane-Shastry type [0.03%]

Federico Finkel
We analyze the thermodynamics and criticality properties of four families of su(m|n) supersymmetric spin chains of Haldane-Shastry (HS) type, related to both the A_{N-1} and the BC_{N} classical root systems. Using a known formula expressin...
Decentralized multiagent reinforcement learning algorithm using a cluster-synchronized laser network [0.03%]

Multiagent reinforcement learning (MARL) studies crucial principles that are applicable to a variety of fields, including wireless networking and autonomous driving. We propose a photonic-based decision-making algorithm to address one of th...
Direct manipulation of diffusion in colloidal glasses via controlled generation of quasi-particle-like defects [0.03%]
通过控制生成准粒子状缺陷直接操控胶体玻璃中的扩散现象

Yi-Di Wang et al.
We experimentally manipulate the structural relaxation of colloidal glass at an atomistically controlled position. We focus a laser beam to eject a particle from the colloidal system. This creates a void that transforms rapidly into a mobil...
Birth, death, and horizontal flight: Malthusian flocks with an easy plane in three dimensions [0.03%]
生育、死亡和水平飞行：三维空间中易于平面的马尔萨斯群 flock

I formulate the theory of three dimensional "Malthusian flocks"-i.e., coherently moving collections of self-propelled entities (such as living creatures) which are being "born" and "dying" during their motion-whose constituents all have a p...
Generalized end-product feedback circuit can sense high-dimensional environmental fluctuations [0.03%]

Understanding computational capabilities of simple biological circuits, such as the regulatory circuits of single-cell organisms, remains an active area of research. Recent theoretical work has shown that a simple cross-talk architecture ba...

The fundamental theoretical problem of the existence of plasma equilibrium in a nonsymmetric magnetic field with nested magnetic surfaces is resolved. The lack of examples of smooth solutions to the equilibrium equations with no symmetry of...
