Abstract

We develop a framework for the stochastic thermodynamics of a probe coupled to a fluctuating medium with spatio-temporal correlations, described by a scalar field. For a Brownian particle dragged by a harmonic trap through a fluctuating Gaussian field, we show that near criticality (where the field displays long-range spatial correlations) the spatially-resolved average heat flux develops a dipolar structure, where heat is absorbed in front and dissipated behind the dragged particle. Moreover, a perturbative calculation reveals that the dissipated power displays three distinct dynamical regimes depending on the drag velocity.

波动相关场中探针的随机热力学

我们建立了一个由标量场描述的探针与具有时空相关性的波动介质耦合的随机热力学框架。对于一个被谐波陷阱拖曳的布朗粒子，在通过波动高斯场时，我们发现在临界点附近（场显示出长程空间相关性），空间分辨平均热通量形成了一个偶极结构，热量在被拖曳粒子的前面吸收，在后面耗散。此外，扰动计算显示，耗散功率显示出三种截然不同的动力学状态，这取决于拖曳速度。

期刊介绍： General physics – physics of elementary particles and fields – nuclear physics – atomic, molecular and optical physics – classical areas of phenomenology – physics of gases, plasmas and electrical discharges – condensed matter – cross-disciplinary physics and related areas of science and technology. Letters submitted to EPL should contain new results, ideas, concepts, experimental methods, theoretical treatments, including those with application potential and be of broad interest and importance to one or several sections of the physics community. The presentation should satisfy the specialist, yet remain understandable to the researchers in other fields through a suitable, clearly written introduction and conclusion (if appropriate). EPL also publishes Comments on Letters previously published in the Journal.
