活性物质有效温度

Effective temperature of active matter

Davide Loi, Stefano Mossa, Leticia F. Cugliandolo

摘要:

我们遵循一个相互作用的自我推进的机动粒子与平衡的热浴接触的合奏动力学。我们发现,波动耗散关系允许定义一个有效的温度,这是兼容的结果使用示踪粒子作为温度计。有效温度取高于浴的温度的值,并且其由电机强度连续控制。

英文摘要:

We follow the dynamics of an ensemble of interacting self-propelled motorized particles in contact with an equilibrated thermal bath. We find that the fluctuation-dissipation relation allows for the definition of an effective temperature that is compatible with the results obtained using a tracer particle as a thermometer. The effective temperature takes a value which is higher than the temperature of the bath and it is continuously controlled by the motor intensity.
