Nonadiabatic Dynamics of Ultracold Fermions in Optical Superlattices
Atsushi Yamamoto, Makoto Yamashita, Norio Kawakami
We study the time-dependent dynamical properties of two-component ultracold fermions in a one-dimensional optical superlattice by applying the adaptive time-dependent density matri…

Z_2-vortex ordering of the triangular-lattice Heisenberg antiferromagnet
Hikaru Kawamura, Atsushi Yamamoto, Tsuyoshi Okubo
Ordering of the classical Heisenberg antiferromagnet on the triangular lattice is studied by means of a mean-field calculation, a scaling argument and a Monte Carlo simulation, wit…
