Conductivity in Pseudogapped Superconductors: The Role of the Fermi Arcs
Dan Wulin, Benjamin M. Fregoso, Hao Guo +2
We calculate the dc conductivity in a pseudogapped high superconductor within a theory which is consistent with gauge invariance. Our results contain additional terms bey…
Perfect Fluids and Bad Metals: Transport Analogies Between Ultracold Fermi Gases and High Superconductors
Hao Guo, Dan Wulin, Chih-Chun Chien +1
In this paper, we examine in a unified fashion dissipative transport in strongly correlated systems. We thereby demonstrate the connection between "bad metals" (such as the high te…
Microscopic Approach to Shear Viscosities in Superfluid Gases: From BCS to BEC
H. Guo, D. Wulin, C. C. Chien +1
We compute the shear viscosity, , at general temperatures , in a BCS-BEC crossover scheme which is demonstrably consistent with conservation laws. The study of is importa…
Establishing the Presence of Coherence in Atomic Fermi Superfluids: Spin-Flip and Spin-Preserving Bragg Scattering at Finite Temperatures
Hao Guo, Chih-Chun Chien, K. Levin
We show how the difference between the finite temperature T structure factors, called S_-, associated with spin and density, can be used as a indication of superfluidity in ultraco…
