Damping of cylindrical phonons in extense fermion matter

A previous model, designed so as to simulate the coupling between a one-dimensional, quantal harmonic excitation in a fermion heat bath, is extended to consider three-dimensional vibrations with axial symmetry. This investigation addresses future studies on the relaxation of collective modes in fini...
