Fermi surface reconstruction in underdoped cuprates: Origin of electron pockets
(American Physical Society, 2018-12-17)
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 ...
Itinerant-localized model of strongly correlated electrons: Fermi surface reconstruction
(American Physical Society, 2017-11-28)
A number of recent experiments have highlighted a remarkable transformation of a large cuprate Fermi surface into small pockets in the underdoped region signaling a breakdown of a conventional Fermi liquid theory in the ...

Electronic structure of reconstructed Au(100): Two-dimensional and one-dimensional surface states
(American Physical Society, 2012-07)
The clean surface of Au(100) presents a complex reconstruction characterized by a hexagonal topmost layer. We report an angle-resolved photoemission study of the electronic structure of this surface, including an analysis ...
Evolution of the electronic structure during the epitaxial growth of Au on Pt(100)
(Elsevier Science, 2016-04)
We report an angle-resolved photoemission study of the electronic structure of Au layers grown epitaxially on Pt(100) in the coverage range 1-10 monolayers (ML). Our results include an analysis of the electronic band ...
Antiferromagnetismo e ordem oculta em um modelo de Anderson
(Universidade Federal de Santa MariaBrasilFísicaUFSMPrograma de Pós-Graduação em FísicaCentro de Ciências Naturais e Exatas, 2018-12-14)
In the absence of an external magnetic field, the heavy-fermion compound URu2Si2 exhibits
a second-order phase transition at 17.5 K. This transition is marked by a mean-field-like
anomaly in the specific heat, by the ...
