Nonequilibrium work distribution of a quantum harmonic oscillator — •Sebastian Deffner and Eric Lutz — Institute of Physics, University of Augsburg, D-86135 Augsburg, Germany

We analytically calculate the work distribution of a quantum harmonic oscillator with arbitrary time--dependent angular frequency. We provide detailed expressions for the work probability density for adiabatic and nonadiabatic processes, in the limit of low and high temperature. We further verify the validity of the quantum Jarzynski equality.
