thermodynamic description of spin-1 nuclei based on the concepts of quantum and statistical mechanics. We explore the dynamical response of the system when driven out
of equilibrium by a work parameter and compute analytically the full distribution of the work generated by the process. Considering work done on the system as a random variable, we collect data for a large number of repeated cyclic processes of finite time. These data of finite time non-equilibrium process will permit us to derive equilibrium values in quantities such as the free energy difference between the final and initial states of the system. Various properties of the system's work distribution are explored.
