Raw data supporting Universal coarsening of a two-dimensional Bose gas under conservative evolution

We investigate the phase ordering dynamics of a uniform two-dimensional Bose gas quenched to a finite temperature in the superfluid phase. Starting from a defect-rich, far-from-equilibrium state, we model the subsequent evolution with the projected Gross–Pitaevskii equation, which conserves both energy and particle number. By tuning the initial energy, we control the effective post-quench temperature and examine its role in the equilibration dynamics.我们针对均匀二维玻色气体（two-dimensional Bose gas）淬灭至超流相内有限温度时的相序动力学展开研究。从富含缺陷的远离平衡初始态出发，我们借助可同时守恒能量与粒子数的投影格罗斯-皮塔耶夫斯基方程（Projected Gross–Pitaevskii equation）对该体系的后续演化过程进行建模。通过调控初始能量，我们能够控制淬灭后的有效温度，并探究该温度在平衡动力学中的作用。
