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…
A significantly stable mode of the ultracold atomic wave packet in amplitude modulated parabolic optical lattices
Tomotake Yamakoshi, Farhan Saif, Shinichi Watanabe
We show that a conspicuous wave packet of ultracold noninteracting Bosonic atoms emerges in a 1-dimensional parabolic optical lattice as in the setup of the Aarhus experiment [P. L…
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…
Single-particle Analysis of Non-interacting Ultracold Bosons in Amplitude Modulated Parabolic Optical Lattice
Tomotake Yamakoshi, Shinichi Watanabe
Ultracold atoms in the combined potential of a parabolic trap and an optical lattice is considered a promising tool for coherent manipulation of matter wave packets. The recent Aar…
Stochastic and equilibrium pictures of the ultracold FFR molecular conversion rate
Tomotake Yamakoshi, Shinichi Watanabe, Chen Zhang +1
The ultracold molecular conversion rate occurring in an adiabatic ramp through a Fano-Feshbach resonance is studied and compared in two statistical models. One model, the so-called…
