Abstract

Author(s): Ilya Ivantsov, Alvaro Ferraz, and Evgenii Kochetov A new phenomenological model is proposed to describe the evolution of the Fermi surface (FS) in a wide range of dopings. It reproduces the key features of the cuprates in the underdoped phase above the superconducting temperature ${T}_{c}$. It is shown that the explicit accounting of strong electron... [Phys. Rev.
