An ultracold heavy Rydberg system formed from ultra-long-range molecules bound in a stairwell potential
Published 2020-01-01“…We propose a scheme to realize a heavy Rydberg system (HRS), a bound pair of oppositely charged ions, from a gas of ultracold atoms. The intermediate step to achieve large internuclear separations is the creation of a unique class of ultra-long-range Rydberg molecules bound in a stairwell potential energy curve. …”

Direct measurement of polariton-polariton interaction strength in the Thomas-Fermi regime of exciton-polariton condensation
Published 2020“…The Thomas-Fermi regime has previously been demonstrated only in ultracold atomic gases in thermal equilibrium. In a nonequilibrium exciton-polariton system, this regime offers a novel opportunity to study interaction-driven effects unmasked by an incoherent reservoir.…”

Weyl points and topological nodal superfluids in a face-centered-cubic optical lattice
Published 2018“…We point out that a face-centered-cubic (fcc) optical lattice, which can be realized by a simple scheme using three lasers, provides one a highly controllable platform for creating Weyl points and topological nodal superfluids in ultracold atoms. In noninteracting systems, Weyl points automatically arise in the Floquet band structure when shaking such fcc lattices, and sophisticated design of the tunneling is not required. …”

Optical spin conductivity in ultracold quantum gases
Published 2022-10-01“…We show that the optical spin conductivity, which is a small ac response of a bulk spin current and elusive in condensed matter systems, can be measured in ultracold atoms. We demonstrate that this conductivity contains rich information on quantum states by analyzing experimentally achievable systems such as a spin-1/2 superfluid Fermi gas, a spin-1 Bose-Einstein condensate, and a Tomonaga-Luttinger liquid. …”

Excited-state quantum phase transitions in spin-orbit-coupled Bose gases

Conversely, we show that the properties of the excited phase can be exploited to prepare stripe states with large and stable density modulations.…”
