Systematic construction of asymptotic quantum many-body scar states and their relation to supersymmetric quantum mechanics
Masaya Kunimi, Yusuke Kato, Hosho Katsura
We develop a systematic method for constructing asymptotic quantum many-body scar (AQMBS) states. While AQMBS states are closely related to quantum many-body scar (QMBS) states, th…
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…
Persistent-current states originating from the Hilbert space fragmentation in momentum space
Masaya Kunimi, Ippei Danshita
Hilbert space fragmentation (HSF) is a phenomenon that the Hilbert space of an isolated quantum system splits into exponentially many disconnected subsectors. The fragmented system…
Ultrafast Many-Body Dynamics in an Ultracold Rydberg-Excited Atomic Mott Insulator
V. Bharti, S. Sugawa, M. Mizoguchi +7
We report the observation and control of ultrafast non-equilibrium many-body electron dynamics in Rydberg-excited spatially-ordered ultracold atoms created from a three-dimensional…
