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…
Structures and proximity effects of inhomogeneous population-imbalanced Fermi gases with pairing interactions
Bishal Parajuli, Devin J. Gagnon, Chih-Chun Chien
By introducing spatially varying profiles of pairing interaction or spin polarization to quasi one-dimensional two-component atomic Fermi gases confined in box potentials, we analy…
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…
Tunable pairing with local spin-dependent Rydberg molecule potentials in an atomic Fermi superfluid
Chih-Chun Chien, Seth T. Rittenhouse, S. I. Mistakidis +1
We explore the energy spectrum and eigenstates of two-component atomic Fermi superfluids with tunable pairing interactions in the presence of spin-dependent ultra long-range Rydber…
