We adapt ideas from geometrical optics and classical billiard dynamics to consider particle trajectories with constant velocity on a cone with specular reflections off an elliptical boundary formed by the intersection with a tilted plane wi...
Quantifying when hyperuniformity of a many-particle system leads to uniformity across length scales [0.03%]
定量分析多粒子系统中超均匀性何时导致各长度尺度上的均匀性

Carlo Vanoni
Hyperuniform systems are distinguished by an unusually strong suppression of large-scale density fluctuations and, consequently, display a high degree of uniformity at the largest length scales. In some cases, however, enhanced uniformity i...
Effect of stochasticity on initial transients and chaotic itinerancy for a natural circulation loop [0.03%]

The introduction of stochastic forcing to dynamical systems has been shown to induce qualitatively different behaviors, such as attractor hopping, to otherwise stable systems as they approach bifurcation. In this study, the effect of stocha...
Coupling an elastic string to an active bath: The emergence of inverse damping [0.03%]

We consider a slow elastic string with Klein-Gordon dynamics coupled to a bath of run-and-tumble particles. We derive and solve the induced Langevin-Klein-Gordon string dynamics with explicit expressions for the streaming term, friction coe...
Fluctuation-response relations and response-response relations for membrane voltage and spike train of stochastic integrate-and-fire neurons [0.03%]
随机积分发放神经元膜电位和脉冲串的起伏响应关系及响应响应关系

Neurons display spontaneous spiking (in the absence of stimulus signals) as well as a characteristic response to time-dependent external stimuli. In a simple but important class of stochastic neuron models, the integrate-and-fire model with...
Spontaneous cholesteric phase in ferroelectric nematic liquid crystals: Preference for integer number of pitches [0.03%]
铁性向列型液晶中胆固醇相的自发形成：整数倍扭折数优势现象

In a ferroelectric nematic liquid crystal, the electrostatic interaction can induce a spontaneous cholesteric helix, even if the material is not chiral. If the liquid-crystal cell is infinitely thick, then the predicted pitch depends contin...
Lattice Boltzmann method for the multiterm time-fractional mixed diffusion and diffusion-wave equations [0.03%]

In this paper, a unified lattice Boltzmann model is developed to solve the multiterm time-fractional mixed diffusion and diffusion-wave equations. To obtain the standard form of the equation, the Caputo derivative terms are approximated usi...

Krylov complexity (K-complexity) is a measure of quantum state complexity that minimizes wave-function spreading across all the possible bases. It serves as a key indicator of operator growth and quantum chaos. In this work, we use K-comple...

By employing Monte Carlo simulations, we investigate the isotropic Heisenberg system model on a simple cubic lattice with short-range interactions, allowing the system to evolve toward a steady state under the influence of competition betwe...

I investigate the formation of multiscale magnetic-field structures in a rotating, self-gravitating dusty plasma comprising electrons, ions, and charged dust grains. By incorporating the gravitomagnetic field, arising from mass currents in ...
