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…
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…
Dissipative Bose-Hubbard system with intrinsic two-body loss
Takafumi Tomita, Shuta Nakajima, Yosuke Takasu +1
We report an experimental study of dynamics of the metastable state of bosonic ytterbium atoms in an optical lattice. The dissipative Bose-Hubbard system with on-site two-b…
Observation of the Mott Insulator to Superfluid Crossover of a Driven-Dissipative Bose-Hubbard System
Takafumi Tomita, Shuta Nakajima, Ippei Danshita +2
Dissipation is ubiquitous in nature and plays a crucial role in quantum systems such as causing decoherence of quantum states. Recently, much attention has been paid to an intrigui…
Topological Thouless Pumping of Ultracold Fermions
Shuta Nakajima, Takafumi Tomita, Shintaro Taie +5
A gas of electrons in a one-dimensional periodic potential can be transported even in the absence of a voltage bias if the potential is modulated slowly and periodically in time. R…
