Suppressed correlation-spreading in a one-dimensional Bose-Hubbard model with strong interactions
Jose Carlos Pelayo, Ippei Danshita
We investigate signatures of non-ergodic behavior in the real-time evolution of a one-dimensional Bose-Hubbard model, where the initial state is a doubly occupied density-wave stat…
Higgs and Nambu-Goldstone modes in a spin-1 model with long-range interactions
Daiki Kawasaki, Ippei Danshita
We theoretically study the collective excitations in a spin-1 model with a quadratic Zeeman term and a long-range interaction that decays algebraically with the distance. Usin…
Stability of current-carrying states in hard-core bosons with long-range hopping on a square lattice
Yoshihiro Yabuuchi, Ippei Danshita
We investigate the stability of current-carrying states with quasi-momentum in the Bose-condensed phase of the hard-core Bose-Hubbard model on a square lattice, where particles…
Observation of anomalous tunneling in collective excitations via a cloud experiment platform for Bose-Einstein condensates
Daichi Kagamihara, Hironori Kazuta, Yewei Wu +2
Recent development of cloud-based experiment platforms has enabled physicists to examine theoretical concepts with unprecedented accessibility. Oqtant is a cloud-accessible platfor…
Entanglement-enhanced correlation propagation in the one-dimensional SU() Fermi-Hubbard model
Mathias Mikkelsen, Ippei Danshita
We investigate the dynamics of correlation propagation in the one-dimensional Fermi-Hubbard model with SU() symmetry when the repulsive-interaction strength is quenched from a l…
Melting of a Bosonic Mott Insulator in Kagome Optical Lattices with Sign-Inverted Hopping
Kazuma Nagao, Daisuke Yamamoto, Seiji Yunoki +1
Using the discrete truncated Wigner approximation (dTWA), we investigate the nonequilibrium dynamics of ultracold bosons confined in optical kagome lattices, focusing on both unfru…
