Perspective on Quantum Bubbles in Microgravity
Nathan Lundblad, David C. Aveline, Antun Balaz +13
Progress in understanding quantum systems has been driven by the exploration of the geometry, topology, and dimensionality of ultracold atomic systems. The NASA Cold Atom Laborator…
Crossovers and quantum phase transitions in two-band superfluids: The evolution from BCS to Bose pairing by tuning interactions and band offset
Yue-Ran Shi, Wei Zhang, Carlos A. R. Sá de Melo
We show that in two-band -wave superfluids it is possible to induce quantum phase transitions (QPTs) by tuning intraband and interband -wave interactions, in sharp contrast t…
Tighter upper bounds on the critical temperature of two-dimensional superconductors and superfluids: Approaching the supremum
Ting ting Shi, Wei Zhang, C. A. R. Sa de Melo
We discuss standard and tighter upper bounds on the critical temperature of two-dimensional superconductors and superfluids versus particle density n or filling factor , u…
Density induced BCS-Bose evolution in gated two-dimensional superconductors: The Berezinskii-Kosterlitz-Thouless transition as a function of carrier density
Tingting Shi, Wei Zhang, C. A. R. Sa de Melo
We discuss the evolution from BCS to Bose superconductivity versus carrier density in gated two-dimensional s-wave superconductors. We show that the transition from the normal to t…
Eigenspectrum, Chern Numbers and Phase Diagrams of Ultracold Color-orbit Coupled SU(3) Fermions in Optical Lattices
Man Hon Yau, C. A. R. Sá de Melo
We study ultracold color fermions with three internal states Red, Green and Blue with symmetry in optical lattices, when color-orbit coupling and color-flip fields ar…
Topological Color-Hall Insulators: SU(3) Fermions in Optical Lattices
Man Hon Yau, C. A. R. Sá de Melo
We discuss the emergence of topological color insulators in optical lattices as quantum phases of SU(3) ultra-cold neutral fermions. We construct the Chern matrix and classify all…
