摘要
The Jarzynski relation aims at an estimate of the free energy change along a finite isotherm. Its application in the quantum domain requires a proper choice of substitute processes combined with quantum mechanical (projective) measurements at the beginning and in the end. The Jarzynski relation can be violated by non-unitary processes like those generated by instantaneous constraint switching (boundary switching). For a complementary model space with a moving barrier of arbitrary, but finite height, the Jarzynski relation is fulfilled. However, its application may be limited due to bad statistics.
