Out-of-equilibrium dynamics of multiple second-order quantum phase transitions in extended Bose-Hubbard model: Superfluid, supersolid and density wave
Keita Shimizu, Takahiro Hirano, Jonghoon Park +2
In this paper, we study the dynamics of the Bose-Hubbard model with the nearest-neighbor repulsion by using time-dependent Gutzwiller methods. Near the unit filling, the phase diag…
Dynamics of first-order quantum phase transitions in extended Bose-Hubbard model: From density wave to superfluid and vice-versa
Keita Shimizu, Takahiro Hirano, Jonghoon Park +2
In this paper, we study the nonequilibrium dynamics of the Bose-Hubbard model with the nearest-neighbor repulsion by using time-dependent Gutzwiller (GW) methods. In particular, we…
Various Topological Mott insulators in strongly-interacting boson system in one-dimensional superlattice
Yoshihito Kuno, Keita Shimizu, Ikuo Ichinose
In this paper, we study a one-dimensional boson system in a superlattice potential.This system is experimentally feasible by using ultracold atomic gases,and attracts much attentio…
