Extended Gutzwiller Approximation for Inhomogeneous System
Wing-Ho Ko, Cody P. Nave, Patrick A. Lee
The generalization of the Gutzwiller approximation to inhomogeneous systems is considered, with extra spin-and-site-dependent fugacity factors included. It is found that the inclus…
Transport Properties of a spinon Fermi surface coupled to a U(1) gauge field
Cody P. Nave, Patrick A. Lee
With the organic compound -(BEDT-TTF)-Cu(CN) in mind, we consider a spin liquid system where a spinon Fermi surface is coupled to a U(1) gauge field. Using the non-e…
Susceptibility of a spinon Fermi surface coupled to a U(1) gauge field
Cody P. Nave, Sung-Sik Lee, Patrick A. Lee
We study the theory of a U(1) gauge field coupled to a spinon Fermi surface. Recently this model has been proposed as a possible description of the organic compound $κ-(BEDT-TTF)_2…
A Variational Monte Carlo Study of the Current Carried by a Quasiparticle
Cody P Nave, Dmitri A. Ivanov, Patrick A. Lee
With the use of Gutzwiller-projected variational states, we study the renormalization of the current carried by the quasiparticles in high-temperature superconductors and of the qu…
