Diffusion quantum aging effects

A modified form of the quantum FDT in an out-of-equilibrium situation, allowing for the description of aging effects, has been proposed in [46,47] for mean-field spin-glass models. Here, we propose a modified form of the quantum FDT which can conveniently be applied to the displacement of the free quantum Brownian particle—that is, to the problem of diffusion.9...
