Effective spin-fermion model for strongly correlated electrons
A. Ferraz, E. Kochetov
TL;DR
This paper introduces a modified spin-fermion model to better understand the complex physics of the underdoped phase in strongly correlated electron systems, specifically within the t-J model framework.
Contribution
The paper presents a new version of the spin-fermion model tailored for the underdoped regime of the t-J model, enhancing the theoretical description of strongly correlated electrons.
Findings
Provides a more accurate description of the underdoped phase
Bridges the gap between spin and fermion dynamics
Offers insights into the pseudogap phenomena
Abstract
