In this work, we study alternating mixed-spin (s,S) Heisenberg ladders in the magnetic field h density matrix renormalization group and linear spin-wave calculations. The h versus interchain coupling J_{⊥} phase diagram for the (1/2,1) cas...
Unexpected effects of disorder on current fluctuations in the symmetric simple exclusion process [0.03%]

We explore how the disorder impacts the current fluctuations in the symmetric simple exclusion process (SSEP) within a heterogeneous environment. First, we analyze the SSEP with a defect site under the periodic boundary conditions. We deriv...

Developing methods to predict electromagnetic instabilities in cardiac dynamics is crucial. However, a comprehensive view of the heart's magnetic activity at a tissue scale is still needed. To address such a challenging problem, we present ...
Cyclical oscillations and absorbing-state probabilities in optional public goods games: Interplay of reward and group size [0.03%]
可选公共物品游戏中的周期振荡和吸收态概率:奖励与群体大小的相互作用

The optional public goods game (OPGG) is a three-strategy model in which individuals can cooperate, defect, or not participate. Despite its simplicity, this model effectively captures various social dilemmas, including those involving publi...
Integer traffic assignment problem: Algorithms and insights on random graphs [0.03%]

Path optimization is a fundamental concern across various real-world scenarios, ranging from traffic congestion issues to efficient data routing over the Internet. The traffic assignment problem (TAP) is a classic continuous optimization pr...
Synchronization and its slow decay in noisy oscillators with simplicial interactions [0.03%]
具有单纯形相互作用的噪声振荡器中的同步及其缓慢衰减
Yuichiro Marui,Hiroshi Kori
Yuichiro Marui
Previous studies on oscillator populations with two-simplex interaction have reported novel phenomena such as discontinuous desynchronization transitions and multistability of synchronized states. However, the noise effect is not well under...
Self-consistent expansion and field-theoretic renormalization group for a singular nonlinear diffusion equation with anomalous scaling [0.03%]
奇异非线扩散方程的自洽展开和场论重正化群研究及其异常标度定律

The method of self-consistent expansions is a powerful tool for handling strong coupling problems that might otherwise be beyond the reach of perturbation theory, providing surprisingly accurate approximations even at low order. First appli...
Conservative phase-field-based lattice Boltzmann equation for gas-liquid-solid flow [0.03%]
基于保守相场的格子Boltzmann方程用于气液固流体模拟

Collective motion in nature, from the murmurations of starlings to firefly flashes, showcases a remarkable level of self-organization. Swarmalator models are an emerging paradigm for describing collective behavior of oscillators which sync ...
