论文摘要
我们研究了具有非马克维亚热储层的两个温度兰格文系统的随机行为。该模型描述了一个二次电势中的过度引导的布朗粒子，并在不同温度下耦合到热浴。储层的特征是高斯白色和彩色噪音以及耗散记忆内核。固定状态表现出由于谐波，摩擦和波动热力而导致随机扭矩影响的非平均平均旋转运动。但是，马尔可夫极限导致热力波动产生的平均扭矩消失。我们还研究记忆对稳态状态中随机热量和熵产生的影响。
We investigate the stochastic behavior of a two-temperature Langevin system with non-Markovian thermal reservoirs. The model describes an overdamped Brownian particle in a quadratic potential and coupled to heat baths at different temperatures. The reservoirs are characterized by Gaussian white and colored noises and a dissipation memory kernel. The stationary states present non-trivial average rotational motion influenced by stochastic torques due to harmonic, friction and fluctuating thermal forces. However, the Markovian limit leads to a vanishing average torque produced by fluctuating thermal forces. We also study the effects of memory on the stochastic heat and the entropy production in the steady-state regime.
