Observation of slow relaxation due to Hilbert space fragmentation in strongly interacting Bose-Hubbard chains
Kantaro Honda, Yosuke Takasu, Shimpei Goto +4
While isolated quantum systems generally thermalize after long-time evolution, there are several exceptions defying thermalization. A notable mechanism of such nonergodicity is the…
Ground-state phase diagram of the SU() Heisenberg model on a plaquette lattice
Ryui Kaneko, Shimpei Goto, Ippei Danshita
We investigate the ground state of the SU() Heisenberg model on a square lattice with spatial anisotropy on each plaquette bond using the tensor-network method based on infinite…
Transition between vacuum and finite-density states in the infinite-dimensional Bose-Hubbard model with spatially inhomogeneous dissipation
Shiono Asai, Shimpei Goto, Ippei Danshita
We analyze dynamics of the infinite-dimensional Bose-Hubbard model with spatially inhomogeneous dissipation in the hardcore boson limit by solving the Lindblad master equation with…
Reentrance of the Disordered Phase in the Antiferromagnetic Ising Model on a Square Lattice with Longitudinal and Transverse Magnetic Fields
Ryui Kaneko, Yoshihide Douda, Shimpei Goto +1
Motivated by recent experiments with Rydberg atoms in an optical tweezer array, we accurately map out the ground-state phase diagram of the antiferromagnetic Ising model on a squar…
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…
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…
Quasiexact Kondo Dynamics of Fermionic Alkaline-Earth-Like Atoms at Finite Temperatures
Shimpei Goto, Ippei Danshita
A recent experiment has observed the antiferromagnetic interaction between the ground state and the metastable state of Yb atoms, which are fermionic. This…
Cooling schemes for two-component fermions in layered optical lattices
Shimpei Goto, Ippei Danshita
Recently, a cooling scheme for ultracold atoms in a bilayer optical lattice has been proposed [A. Kantian et al., arXiv:1609.03579]. In their scheme, the energy offset between the…
