Larkin-Ovchinnikov-Fulde-Ferrell state of spin polarized atomic Fermi superfluid on a spherical surface
Yan He, Chih-Chun Chien
By implementing the Bogoliubov-de Gennes (BdG) formalism of population-imbalanced atomic Fermi gases with pairing interactions in a thin spherical shell, we characterize the Larkin…

Approximate vortex lattices of atomic Fermi superfluid on a spherical surface
Keshab Sony, Yan He, Chih-Chun Chien
While planar Fermi superfluids form Abrikosov vortex lattices under magnetic or effective gauge fields, spherical geometry forbids perfect lattices above 20 vortices. We characteri…

Two-component atomic Fermi superfluid with spin-orbital coupling in thin spherical-shell geometry
Yan He, Chih-Chun Chien
We present a theory of two-component atomic Fermi superfluid with tunable pairing interaction in a thin spherical shell subject to spin-orbit coupling (SOC). By incorporating SOC i…
