Real-space BCS-BEC crossover in FeSe monolayer
Haicheng Lin, Wantong Huang, Gautam Rai +7
The quantum many body states in the BCS-BEC crossover regime are of long-lasting interest. Here we report direct spectroscopic evidence of BCS-BEC crossover in real-space in a FeSe…
Stable Sarma State in Two-band Fermi Systems
Lianyi He, Pengfei Zhuang
We investigate fermionic superconductivity with mismatched Fermi surfaces in a general two-band system. The exchange interaction between the two bands changes significantly the sta…
Critical Zeeman Splitting of Fermi Superfluidity at Infinite Scattering Length
Lianyi He, Pengfei Zhuang
We determine the critical Zeeman energy splitting for Fermi superfluidity at infinite s-wave scattering length according to the Monte Carlo and experimental results of the equation…
Phase Diagram of Cold Polarized Fermi Gas in Two Dimensions
Lianyi He, Pengfei Zhuang
The superfluid phase diagrams of a two-dimensional cold polarized Fermi gas in the BCS-BEC crossover are systematically and analytically investigated. In the BCS-Leggett mean field…
Finite Temperature Phase Diagram of a Two-Component Fermi Gas with Density Imbalance
Lianyi He, Meng Jin, Pengfei Zhuang
We investigated possible superfluid phases at finite temperature in a two-component Fermi gas with density imbalance. In the frame of a general four-fermion interaction theory, we…
Fermion Cooper Pairing with Unequal Masses: Standard Field Theory Approach
Lianyi He, Meng Jin, Pengfei Zhuang
The fermion Cooper pairing with unequal masses is investigated in a standard field theory approach. We derived the superfluid density and Meissner mass squared of the U(1) gauge fi…
