* ABSTRACT

The transient fluctuation theorems by Jarzynski and Crooks deal with the response of a classical system initially staying in thermal equilibrium on the application of external forces. In particular, these theorems relate the statistics of the applied work resulting from a large number of repetitions of the same force protocol, with the free energy difference between the equilibrium state of the system at those force, or, more generally, parameter values that have been reached at the end of the protocol, and of the initial equilibrium state.
The theorems are of general validity concerning the form of the protocol; in particular they are not restricted to slow processes.
In the present talk I shall demonstrate that these theorems are equally valid in the framework of quantum statistical mechanics and shall discuss variants for micro- and grand-canonical initial states, the influence of possible measurements during the force protocol as well as the validity of the theorems for arbitrary open systems.
