The Origin of Fermi Arcs in Cuprate Pseudogap States and Strong Constraints on Viable Theories of High-Temperature Superconductivity
Mike Guidry, Yang Sun, Cheng-Li Wu
A full Fermi surface exists in underdoped high-temperature superconductors if the temperature T lies above the pseudogap temperature T*. Below T* only arcs of Fermi surface survive…
k-dependent SU(4) model of high-temperature superconductivity and its coherent-state solutions
Yang Sun, Mike Guidry, Cheng-Li Wu
We extend the SU(4) model [1-5] for high-Tc superconductivity to an SU(4)k model that permits explicit momentum (k) dependence in predicted observables. We derive and solve gap equ…
Pairing Gaps, Pseudogaps, and Phase Diagrams for Cuprate Superconductors
Yang Sun, Mike Guidry, Cheng-Li Wu
We use a symmetry-constrained variational procedure to construct a generalization of BCS to include Cooper pairs with non-zero momentum and angular momentum. The resulting gap equa…
Temperature-dependent gap equations and their solutions in the SU(4) model of high-temperature superconductivity
Yang Sun, Mike Guidry, Cheng-Li Wu
Temperature-dependent gap equations in the SU(4) model of high-Tc superconductivity are derived and analytical solutions are obtained. Based on these solutions, a generic gap diagr…
SU(4) Model of High-Temperature Superconductivity: Manifestation of Dynamical Symmetry in Cuprates
Yang Sun, Mike Guidry, Cheng-Li Wu
The mechanism that leads to high-temperature superconductivity in cuprates remains an open question despite intense study for nearly two decades. Here, we introduce an SU(4) model…
Mott Insulators, No-Double-Occupancy, and Non-Abelian Superconductivity
Mike Guidry, Yang Sun, Cheng-Li Wu
SU(4) dynamical symmetry is shown to imply a no-double-occupancy constraint on the minimal symmetry description of antiferromagnetism and d-wave superconductivity. This implies a m…
