Superfluid to Mott insulator transition in the one-dimensional Bose-Hubbard model for arbitrary integer filling factors
Ippei Danshita, Anatoli Polkovnikov
We study the quantum phase transition between the superfluid and the Mott insulator in the one-dimensional (1D) Bose-Hubbard model. Using the time-evolving block decimation method,…
Quantum phase slips in one-dimensional superfluids in a periodic potential
Ippei Danshita, Anatoli Polkovnikov
We study the decay of superflow of a one-dimensional (1D) superfluid in the presence of a periodic potential. In 1D, superflow at zero temperature can decay via quantum nucleation…
Detecting paired and counterflow superfluidity via dipole oscillations
Anzi Hu, L. Mathey, Eite Tiesinga +3
We suggest an experimentally feasible procedure to observe paired and counterflow superfluidity in ultra-cold atom systems. We study the time evolution of one-dimensional mixtures…
Dipolar Bosons in Triangular Optical Lattices: Quantum Phase Transitions and Anomalous Hysteresis
Daisuke Yamamoto, Ippei Danshita, Carlos A. R. Sá de Melo
We study phase transitions and hysteresis in a system of dipolar bosons loaded into triangular optical lattices at zero temperature. We find that the quantum melting transition fro…
