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…
Matrix product state approach for a quantum system at finite temperatures using random phases and Trotter gates
Shimpei Goto, Ryui Kaneko, Ippei Danshita
We develop a numerical method based on matrix product states for simulating quantum many-body systems at finite temperatures without importance sampling and evaluate its performanc…
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…
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…
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…
