论文摘要
最近的经验研究发现，动物集体运动的不同热力学阶段。但是，这种对人运动的热力学描述尚不清楚，这主要是由于现有跟踪技术的分辨率有限。在这封信中，我们使用了新的超宽带射频标识技术来收集用于课堂运动的高分辨率时空数据。我们测量了基础系统的有效温度，并发现了两个与不同温度相关的社会阶段，即气体和液相蒸气共存。我们还提出了一个简单的统计物理模型，该模型可以再现不同的经验观察到的阶段。
Recent empirical studies found different thermodynamic phases for collective motion in animals. However, such a thermodynamic description for human movement remains unclear, mainly due to the limited resolution of existing tracking technologies. In this Letter, we used a new ultra-wideband radio frequency identification technology to collect high-resolution spatial-temporal data for classroom movements. We measured the effective temperatures for the underlying systems, and found two social phases, gas and liquid-vapor coexistence, associated with different temperatures. We also proposed a simple statistical physics model that can reproduce different empirically observed phases.
