Thermally activated phase slips of one-dimensional Bose gases in shallow optical lattices
Masaya Kunimi, Ippei Danshita
We study the decay of superflow via thermally activated phase slips in one-dimensional Bose gases in a shallow optical lattice. By using the Kramers formula, we numerically calcula…
Creating and probing the Sachdev-Ye-Kitaev model with ultracold gases: Towards experimental studies of quantum gravity
Ippei Danshita, Masanori Hanada, Masaki Tezuka
We suggest that the holographic principle, combined with recent technological advances in atomic, molecular, and optical physics, can lead to experimental studies of quantum gravit…
Topological and dynamical properties of a generalized cluster model in one dimension
Takumi Ohta, Shu Tanaka, Ippei Danshita +1
We study the ground-state phase diagram and dynamics of the one-dimensional cluster model with several competing interactions. Paying particular attention to the relation between t…
Damping of the Higgs and Nambu-Goldstone modes of superfluid Bose gases at finite temperatures
Kazuma Nagao, Ippei Danshita
We study collective modes of superfluid Bose gases in optical lattices at commensurate fillings. We focus on the vicinity of the quantum phase transition to the Mott insulator, whe…
