Abstract:
In the second part we focus on quasistatic processes connecting
nonequilibrium steady states within the framework of Markovian systems
out of detailed balance. We give details of the construction of finite
(.excess.) parts for diverging path quantities like heat or work of
non-potential forces in the quasistatic limit, and set up a systematic
expansion around detailed balance. As an application, we calculate a
lowest-order nonequilibrium correction to the (equilibrium) heat
capacity and show that in general non-equlibrium processes cannot be
described by generalized thermodynamic potentials.
