Performance evaluation of the discrete truncated Wigner approximation for quench dynamics of quantum spin systems with long-range interactions
Masaya Kunimi, Kazuma Nagao, Shimpei Goto +1
The discrete truncated Wigner approximation (DTWA) is a powerful tool for analyzing dynamics of quantum spin systems. Since the DTWA includes the leading-order quantum corrections…
SU(3) truncated Wigner approximation for strongly interacting Bose gases
Kazuma Nagao, Yosuke Takasu, Yoshiro Takahashi +1
We develop and utilize the SU(3) truncated Wigner approximation (TWA) in order to analyze far-from-equilibrium quantum dynamics of strongly interacting Bose gases in an optical lat…
Minimally entangled typical thermal states algorithm with Trotter gates
Shimpei Goto, Ippei Danshita
We improve the efficiency of the minimally entangled typical thermal states (METTS) algorithm without breaking the Abelian symmetries. By adding the operation of Trotter gates that…
Semiclassical dynamics of a dark soliton in a one-dimensional bosonic superfluid in an optical lattice
Yusuke Ozaki, Kazuma Nagao, Ippei Danshita +1
We study quantum dynamics of a dark soliton in a one-dimensional Bose gas in an optical lattice within the truncated Wigner approximation. A previous work has revealed that in the…
Energy redistribution and spatio-temporal evolution of correlations after a sudden quench of the Bose-Hubbard model
Yosuke Takasu, Tomoya Yagami, Hiroto Asaka +5
An optical-lattice quantum simulator is an ideal experimental platform to investigate non-equilibrium dynamics of a quantum many-body system, which is in general hard to simulate w…
Measurement-induced transitions of the entanglement scaling law in ultracold gases with controllable dissipation
Shimpei Goto, Ippei Danshita
Recent studies of quantum circuit models have theoretically shown that frequent measurements induce a transition in a quantum many-body system, which is characterized by the change…
