标题： Current large deviations in a driven dissipative model

摘要： 我们考虑体相中存在生成-湮灭的格子气体扩散动力学，并通过边界处的两个储层维持非平衡状态。 这个随机粒子系统可以看作是颗粒气体的一个简化模型，其中能量在边界被注入并在体相中耗散。 计算了通过系统流动的粒子电流的大偏差泛函，并讨论了一些物理后果：局部电流涨落的机制、动态相变、涨落关系。 显示英文摘要

摘要： We consider lattice gas diffusive dynamics with creation-annihilation in the bulk and maintained out of equilibrium by two reservoirs at the boundaries. This stochastic particle system can be viewed as a toy model for granular gases where the energy is injected at the boundary and dissipated in the bulk. The large deviation functional for the particle currents flowing through the system is computed and some physical consequences are discussed: the mechanism for local current fluctuations, dynamical phase transitions, the fluctuation-relation.
