The role of frozen disorder in non-equilibrium work and fluctuation theorems is to be investigated. Besides systems that are driven away from thermodynamic equilibrium according to some specific protocol and those that are kept in a non-equilibrium steady state by appropriate boundary conditions, glassy systems may form a third general class of non-equilibrium situations for which fluctuation theorems are relevant. In these systems competing interactions block the way to complete equilibration and relaxation ends in a highly disordered metastable state. The static randomness of this state may contribute to the thermodynamic entropy and should then show up in appropriate versions of fluctuation theorems. In addition to the general interest for stochastic thermodynamics the role of static disorder for fluctuation theorems is connected with several fascinating problems at the borderline between statistical mechanics and information theory including models of Maxwell's demon, the thermodynamic cost of acquisition and erasure of information, and the accuracy of processing genetic information. The investigation of these rather general issues will be made concrete and qualitative by scrutinizing a model for the non-equilibrium growth of an information carrying co-polymer introduced recently.

冻结无序在非平衡功和涨落定理中的作用有待研究。除了根据某些特定协议被驱离热力学平衡的系统和那些通过适当的边界条件保持在非平衡稳态的系统之外，玻璃态系统可以形成第三类一般的非平衡情形，涨落定理与之相关。在这些系统中，相互竞争的相互作用阻碍了完全平衡的方式，并且弛豫以高度无序的亚稳态结束。这种状态的静态随机性可能对热力学熵有贡献，然后应该在涨落定理的适当版本中显示出来。除了一般的兴趣随机热力学的作用，静态无序波动定理与几个迷人的问题之间的边界，统计力学和信息理论，包括模型的麦克斯韦的恶魔，热力学成本的收购和擦除的信息，和准确性处理遗传信息。这些相当普遍的问题的调查将具体和定性的审查模型的非平衡增长的信息携带共聚物最近推出。
