Contemporary tensor network approaches to gapless and topological phases in an extended Bose-Hubbard ladder
Yuma Watanabe, Ravindra W. Chhajlany, Maciej Lewenstein +2
The development of numerically efficient computational methods has facilitated in depth studies of various correlated phases of matter including critical and topological phases. A…
Transverse Field Dependence of the Ground State in the Z2 Bose-Hubbard Model
Yuma Watanabe, Shohei Watabe, Tetsuro Nikuni
The study of interaction between the particle and lattice degrees of freedom is one of the central interests in the quantum many-body systems. The Z2 Bose-Hubbard model has been pr…
Competing order in two-band Bose-Hubbard chains with extended-range interactions
Yuma Watanabe, Utso Bhattacharya, Ravindra W. Chhajlany +3
Motivated by the recent progress in realizing and controlling extended Bose-Hubbard systems using excitonic or atomic devices, the present Letter theoretically investigates the cas…
Propagation of phase-imprinted solitons from superfluid core to Mott-insulator shell and superfluid shell
Yuma Watanabe, Shohei Watabe, Tetsuro Nikuni
We study phase-imprinted solitons of ultracold bosons in an optical lattice with a harmonic trap, which shows the superfluid (SF) and Mott-insulator (MI) shell structures. The earl…
