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…
Structure and scaling of Kitaev chain across a quantum critical point in real space
Yan He, Chih-Chun Chien
The spatial Kibble-Zurek mechanism (KZM) is applied to the Kitaev chain with inhomogeneous pairing interactions that vanish in half of the lattice and result in a quantum critical…
Vortex structure and spectrum of atomic Fermi superfluid in a spherical bubble trap
Yan He, Chih-Chun Chien
The structures of multiply quantized vortices (MQVs) of an equal-population atomic Fermi superfluid in a rotating spherical bubble trap approximated as a thin shell are analyzed by…
Geometric phases of Topological Systems under Quench Process
Zhan Gao, Yan He
We study the time evolution of geometric phases of one dimensional topological models under the quench dynamics. Taking the Creutz ladder model as an example, it is found that the…
