Analysis of Particle Transfer by Periodic Lattice Modulation for Ultracold Fermionic Atom Systems in Three Dimensional Optical Lattice
Motoyoshi Inoue, Yusuke Nakamura, Yoshiya yamanaka
We analyze a ultracold fermionic atom system in a three dimensional optical lattice with a confinement harmonic potential, using the Hubbard model, and time-dependent Gutzwiller va…

Tunneling Time of Bose-Einstein Condensates on Real Time Stochastic Approach
K. Kobayashi, M. Inoue, Y. Nakamura +2
We study tunneling processes of Bose-Einstein condensate (BEC) on the real time stochastic approach and reveal some properties of their tunneling time. An important result is that…

Effects of finite temperature on the robustness of the Mott insulator phase in pseudo one-dimensional Bose-Hubbard Model
Motoyoshi Inoue, Keita Kobayashi, Yusuke Nakamura +1
We study the superfluid-Mott insulator (SF-MI) transition in an one-dimensional optical lattice system, and employ the Bose-Hubbard model in two dimension with a combined potential…
