Theory of THz Conductivity in the Pseudogap Phase of the Cuprates: A Pre-Formed Pair Perspective
Dan Wulin, V. Mishra, K. Levin
In this paper we deduce transport properties in the presence of a pseudogap associated with precursor superconductivity. Our theoretical analysis is based on the widely adopted sel…
Theory of Diamagnetism in the Pseudogap Phase: Implications from the Self energy of Angle Resolved Photoemission
Dan Wulin, K. Levin
In this paper we apply the emerging- consensus understanding of the fermionic self energy deduced from angle resolved photoemisssion spectroscopy (ARPES) experiments to deduce the…
Transport Anomalies Associated with the Pseudogap From a Preformed Pair Perspective
Vivek Mishra, Dan Wulin, K. Levin
Transport studies seem to be one of the strongest lines of support for a preformed pair approach to the pseudogap. In this paper we provide a fresh, physically transparent look at…
General pairing theory for condensed and non-condensed pairs of a superconductor in a high magnetic field
Peter Scherpelz, Dan Wulin, Břetislav Šopík +2
We extend Gor'kov theory to address superconducting pairing at high magnetic fields and general temperatures with arbitrary attractive interaction strength. This analysis begins wi…
The Two Component Optical Conductivity in the Cuprates: A Necessary Consequence of Preformed Pairs
Dan Wulin, Hao Guo, Chih-Chun Chien +1
We address how the finite frequency real conductivity in the underdoped cuprates is affected by the pseudogap, contrasting the behavior above and below . The f-sum rule…
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…
Contrasting Nodal and Anti-Nodal Behavior in the Cuprates Via Multiple Gap Spectroscopies
Dan Wulin, Chih-Chun Chien, Dirk K. Morr +1
Using a precursor superconductivity scenario for the cuprates we present a theory for the temperature dependent behavior of the spectral gaps associated with four distinct spectros…
