Semiclassical quench dynamics of Bose gases in optical lattices
Kazuma Nagao, Masaya Kunimi, Yosuke Takasu +2
We analyze the time evolution of the Bose-Hubbard model after a sudden quantum quench to a weakly interacting regime. Specifically, motivated by a recent experiment at Kyoto Univer…
Dissipative Bose-Hubbard system with intrinsic two-body loss
Takafumi Tomita, Shuta Nakajima, Yosuke Takasu +1
We report an experimental study of dynamics of the metastable state of bosonic ytterbium atoms in an optical lattice. The dissipative Bose-Hubbard system with on-site two-b…
Experimental Determination of Bose-Hubbard Energies
Yusuke Nakamura, Yosuke Takasu, Jun Kobayashi +5
We present the first experimental measurement of the ensemble averages of both the kinetic and interaction energies of the three-dimensional Bose--Hubbard model at finite temperatu…
Antiferromagnetic spin correlation of SU() Fermi gas in an optical super-lattice
Hideki Ozawa, Shintaro Taie, Yosuke Takasu +1
Large-spin cold atomic systems can exhibit unique phenomena that do not appear in spin-1/2 systems. We report the observation of nearest-neighbor antiferromagnetic spin correlation…
