Non-Hermitian -wave superfluid and effects of the inelastic three-body loss in a one-dimensional spin-polarized Fermi gas

Hiroyuki Tajima, Yuta Sekino, Daisuke Inotani +3

We theoretically investigate non-Hermitian -wave Fermi superfluidity in one-dimensional spin-polarized Fermi gases which is relevant to recent ultracold atomic experiments. Cons…

Non-Hermitian topological Fermi superfluid near the -wave unitary limit

Hiroyuki Tajima, Yuta Sekino, Daisuke Inotani +3

We theoretically discuss the non-Hermitian superfluid phase transition in one-dimensional two-component Fermi gases near the -wave Feshbach resonance accompanied by the two-body…

Dissipation-induced dynamical phase transition in postselected quantum trajectories

Tomoya Hayata, Yoshimasa Hidaka, Arata Yamamoto

It is known that effects of dissipation or measurement backreaction in postselected quantum trajectories are described by non-Hermitian Hamiltonian, but their consequences in real-…

Chiral magnetic effect by synthetic gauge fields

Tomoya Hayata, Masahito Ueda

We study the dynamical generation of the chiral chemical potential in a Weyl metal constructed from a three-dimensional optical lattice and subject to synthetic gauge fields. By nu…

Complex Langevin simulation of quantum vortices in a Bose-Einstein condensate

Tomoya Hayata, Arata Yamamoto

The ab-initio simulation of quantum vortices in a Bose-Einstein condensate is performed by adopting the complex Langevin techniques. We simulate the nonrelativistic boson field the…
