Chiral Active Rods Simulation Data II

Simulation data of agent-based simulations of active point particles following the following overdamped Langevin dynamics: d/dt x_i= v* cos(phi_i) d/dt y_i= v* sin(phi_i) d/dt phi_i= omega + gamma*\sum_{j is neighbor of i} sin[2*(phi_j-phi_i)] + sigma*xi_i with independent Gaussian white noise xi_i. i and j are considered to be neighbors if their distance is less than R. Parameters: sigma=sqrt(2), R=1, v=1, simulation box size: Lx=Ly=sqrt(N/10), N, gamma, omega are given in the data base. Periodic boundary conditions are used. Euler-Maruyama scheme was used to integrate the equations of motion.该数据集为基于智能体的活性点粒子模拟的仿真数据，其遵循下述过阻尼朗之万动力学方程： d/dt x_i = v·cos(φ_i)，d/dt y_i = v·sin(φ_i)，d/dt φ_i = ω + γ·∑_{j为i的邻域粒子} sin[2·(φ_j - φ_i)] + σ·ξ_i 其中ξ_i为独立高斯白噪声。当粒子i与j的间距小于R时，二者被视作邻域粒子。参数设置如下：σ=√2，R=1，v=1，模拟盒子尺寸Lx=Ly=√(N/10)；N、γ、ω的具体取值由数据库给出。本次模拟采用周期性边界条件，运动方程的积分通过欧拉-丸山（Euler-Maruyama）格式完成。
