Abstract
In a recent work, an extension of one-body transport model has been proposed by Ayik and Gregoire by incorporating dynamical fluctuations into the equation of motion for single-particle density. In addition to its various applications at intermediate energies, this model provides a microscopic and numerically tractable description for dissipation and fluctuation properties of large amplitude collective motion at low energies. This is illustrated by projecting the one-body transport equation into a collective subspace which yields a collective transport model known from phenomenological studies of damped nuclear collisions and induced fission, and provides an explicit calculation of transport coefficients with memory effects.
