Equivalence of dissipative and dissipationless dynamics of interacting quantum systems with its application to the unitary Fermi gas
arXiv:2106.13621 · doi:10.3389/fphy.2021.730761
Abstract
We analytically study quantum dissipative dynamics described by the Caldirola-Kanai model with inter-particle interactions. We have found that the dissipative quantum dynamics of the Caldirola-Kanai model can be exactly mapped to a dissipationless quantum dynamics under a negative external harmonic potential, even when the particles are strongly interacting. In particular, we show that the mapping is valid for the unitary Fermi gas, which is relevant for cold atoms and nuclear matters.
