Loading ultracold atoms onto nonlinear Bloch states and soliton states in bichromatic lattices
Tomotake Yamakoshi, Shinichi Watanabe
We simulate and analyze an experimental method of loading interacting ultracold atoms onto nontrivial quantum states such as nonlinear Bloch wave and soliton solutions in a 1-dimen…

Fast and selective inter-band transfer of ultracold atoms in bichromatic lattices permitting Dirac points
Tomotake Yamakoshi, Shinichi Watanabe
An experimental group at Beijing[Yueyang Zhai, , Phys. Rev. A , 063638 (2013)] introduced the method of standing-wave pulse sequence for efficiently prepar…

Dynamics of fermions in an amplitude modulated lattice
Tomotake Yamakoshi, Shinichi Watanabe, Shun Ohgoda +1
We study dynamics of fermions loaded in an optical lattice with a superimposed parabolic trap potential. In the recent Hamburg experiments [J.Heinze et.al., Phys. Rev. Lett. 110, 0…
