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…
Quantum many-body scars in the Bose-Hubbard model with a three-body constraint
Ryui Kaneko, Masaya Kunimi, Ippei Danshita
We uncover the exact athermal eigenstates in the Bose-Hubbard (BH) model with a three-body constraint, motivated by the exact construction of quantum many-body scar (QMBS) states i…
Proposal for simulating quantum spin models with the Dzyaloshinskii-Moriya interaction using Rydberg atoms and the construction of asymptotic quantum many-body scar states
Masaya Kunimi, Takafumi Tomita, Hosho Katsura +1
We have developed a method to simulate quantum spin models with the Dzyaloshinskii-Moriya interaction (DMI) using Rydberg atom quantum simulators. Our approach involves a two-photo…
Nonergodic dynamics of the one-dimensional Bose-Hubbard model with a trapping potential
Masaya Kunimi, Ippei Danshita
We investigate nonergodic behavior of the one-dimensional Bose-Hubbard model, which emerges in the unitary quantum dynamics starting with initial-state $|ψ(0)\rangle=|\cdots 2020\c…
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…
Nonequilibrium steady states of Bose-Einstein condensates with a local particle loss in double potential barriers
Masaya Kunimi, Ippei Danshita
We investigate stability of non-equilibrium steady states of Bose-Einstein condensates with a local one-body loss in the presence of double potential barriers. We construct an exac…
