Ultra-cold fermions in the flatland: evolution from BCS to Bose superfluidity in two-dimensions with spin-orbit and Zeeman fields
Li Han, C. A. R. Sá de Melo
We discuss the evolution from BCS to Bose superfluidity for ultracold fermions in two-dimensions and in the presence of simultaneous spin-orbit and Zeeman fields. We analyze severa…
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…
The evolution from BCS to BEC superfluidity in the presence of disorder
Li Han, C. A. R. Sá de Melo
We describe the effects of disorder on the critical temperature of -wave superfluids from the BCS to the BEC regime, with direct application to ultracold fermions. We use the fu…
