Dissipative dynamics of a fermionic superfluid with two-body losses
G. Mazza, Marco Schirò
Abstract
A sudden change of pairing interaction leads to coherent solitonlike oscillations of the superfluid order parameter. Here, the authors study the effect of pair losses on the dynamics of a quenched fermionic superfluid and reveal that even a tiny dissipation leads to a large renormalization of the soliton period. They explain the effect through a dissipative soliton model and a variational approach for the Markovian quantum dynamics.
