Bose polaron in spherical trap potentials: Spatial structure and quantum depletion
Junichi Takahashi, Ryosuke Imai, Eiji Nakano +1
We investigate how the presence of a localized impurity in a Bose-Einstein condensate of trapped cold atoms that interact with each other weakly and repulsively affects the profile…

Dynamical properties of the finite-size Dicke model coupled to a thermal reservoir
Ryosuke Imai, Yoshiya Yamanaka
We investigate the dynamical properties of the finite-size Dicke model coupled to a photon reservoir in the dispersive regime. The system-reservoir coupling in our Hamiltonian incl…
