Theories of Linear Response in BCS Superfluids and How They Meet Fundamental Constraints
Hao Guo, Chih-Chun Chien, Yan He
We address the importance of symmetry and symmetry breaking on linear response theories of fermionic BCS superfluids. The linear theory of a noninteracting Fermi gas is reviewed an…
Phase diagrams of Fermi gases in a trap with mass and population imbalances at finite temperature
Jibiao Wang, Hao Guo, Qijin Chen
The pairing and superfluid phenomena in a two-component Fermi gas can be strongly affected by the population and mass imbalances. Here we present phase diagrams of atomic Fermi gas…
Gauge Invariant Linear Response Theory of Relativistic BCS superfluids
Hao Guo, Chih-Chun Chien, Yan He
We develop a gauge-invariant linear response theory for relativistic Bardeen-Cooper-Schrieffer (BCS) superfluids based on a consistent-fluctuation-of-the order-parameter (CFOP) app…
Comment on "Density and Spin response of a strongly-interacting Fermi gas in the attractive and quasi-repulsive regime"
Chi-Chun Chien, Hao Guo, K. Levin
This is a comment on Phys. Rev. Lett. 108, 080401 (2012) by Palestini et al. We pointed out that the diagrammatic method in that article violates gauge invariance. As a consequence…
