Shapiro steps of superfluid Fermi gases in a ring trap across the BCS--BEC crossover
Hikaru Kuriki, Masaya Kunimi, Tetsuro Nikuni
We investigate the transport properties of a superfluid Fermi gas confined in a ring trap with a moving potential barrier across the Bardeen-Cooper-Schrieffer (BCS) to Bose-Einstei…
Magnetic-field control of interactions in alkaline-earth Rydberg atoms and applications to {\it XXZ} models
Masaya Kunimi, Takafumi Tomita
We study the magnetic-field dependence of the interactions between two alkaline-earth(-like) Rydberg atoms, Sr and Yb. Considering the pair of Rydberg states $|n…
Proposal for realizing Heisenberg-type quantum-spin models in Rydberg-atom quantum simulators
Masaya Kunimi, Takafumi Tomita
We investigate the magnetic-field dependence of the interaction between two Rydberg atoms, and . In this setting, the effective s…
Proposal for experimental realization of quantum spin chains with quasiperiodic interactions using Rydberg atoms
Takaharu Yoshida, Masaya Kunimi, Tetsuro Nikuni
Investigating localization properties of interacting disordered systems plays a crucial role in understanding thermalization and its absence in closed quantum systems. However, sim…
Proposal for realizing quantum-spin systems on a two-dimensional square lattice with Dzyaloshinskii-Moriya interaction by Floquet engineering using Rydberg atoms
Hiroki Kuji, Masaya Kunimi, Tetsuro Nikuni
We theoretically propose a method for implementing the Hamiltonian incorporating Heisenberg and Dzyaloshinskii-Moriya (DM) interactions within Rydberg atoms arranged in a two-dimen…
