Path Entropy Changes in Adiabatic Approximation
Abstract
By applying adiabatic theorem to a Markovian system, we calculate the adiabatic and diabatic entropy changes along a path. As well known, the total path entropy change is separated into two parts, system and environment entropy changes, . The environment entropy change, , is divided again into two parts, an adiabatic contribution due to work, , and a diabatic contributions due to heat, . In an adiabatic process, total path entropy change is same with the adiabatic path entropy change, , which is given by sum of system entropy change and adiabatic contribution, . Mathematical form of is a type of excess heat entropy change, but is due to work. By which, it is shown that the terms adiabatic and non-adiabatic contributions of and in [Phys. Rev. Lett. {\bf 104}, 090601 (2010)] should be completely switched, and in fact.
