Who is the Lord of the Rings: Majorana, Dirac or Lifshitz? The Spin-Orbit-Zeeman Saga in Ultra-cold Fermions
Kangjun Seo, Li Han, C. A. R. Sá de Melo
We discuss the emergence of rings of zero-energy excitations in momentum space for superfluid phases of ultra-cold fermions when spin-orbit, Zeeman fields and interactions are vari…
Artificial spin-orbit coupling in ultra-cold Fermi superfluids
Kangjun Seo, Li Han, C. A. R. Sá de Melo
We develop a theory for interacting fermions in the presence of spin-orbit coupling and Zeeman fields, and show that many new superfluids phases, which are topological in nature, e…
Topological phase transitions in ultra-cold Fermi superfluids: the evolution from BCS to BEC under artificial spin-orbit fields
Kangjun Seo, Li Han, C. A. R. Sá de Melo
We discuss topological phase transitions in ultra-cold Fermi superfluids induced by interactions and artificial spin orbit fields. We construct the phase diagram for population imb…
Evolution from BCS to BEC superfluidity in the presence of spin-orbit coupling
Li Han, C. A. R. Sá de Melo
We discuss the evolution from BCS to BEC superfluids in the presence of spin-orbit coupling, and show that this evolution is just a crossover in the balanced case. The dependence o…
Dipolar Bosons in Triangular Optical Lattices: Quantum Phase Transitions and Anomalous Hysteresis
Daisuke Yamamoto, Ippei Danshita, Carlos A. R. Sá de Melo
We study phase transitions and hysteresis in a system of dipolar bosons loaded into triangular optical lattices at zero temperature. We find that the quantum melting transition fro…
Density fluctuations and compressibility matrix for population or mass imbalanced Fermi-Fermi mixtures
Kangjun Seo, C. A. R. Sá de Melo
We describe the relation between the isothermal atomic compressibility and density fluctuations in mixtures of two-component fermions with population or mass imbalance. We derive a…
