Analysis of shape change of droplet in dipolar Bose-Hubbard model
Kazuhiro Tamura, Shohei Watabe, Tetsuro Nikuni
The long-range and anisotropic nature of the dipolar interaction provides the so-called supersolid phases in Bose-Einstein condensates (BECs) in an optical lattice. However, in a c…

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…
