Quantum decoherence of a charge qubit in a spin-fermion model
R. M. Lutchyn, L. Cywinski, Cody P. Nave +1
We consider quantum decoherence in solid-state systems by studying the transverse dynamics of a single qubit interacting with a fermionic bath and driven by external pulses. Our in…
How to Enhance Dephasing Time in Superconducting Qubits
L. Cywinski, R. M. Lutchyn, C. P. Nave +1
We theoretically investigate the influence of designed pulse sequences in restoring quantum coherence lost due to background noise in superconducting qubits. We consider both 1/f n…
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…
Tensor renormalization group approach to 2D classical lattice models
Michael Levin, Cody P. Nave
We describe a simple real space renormalization group technique for two dimensional classical lattice models. The approach is similar in spirit to block spin methods, but at the sa…
