Magnetic impurities in a charge-ordered background
Sebastião dos Anjos Sousa-Júnior, Raimundo R. dos Santos, Natanael C. Costa
We investigate how magnetic impurities may affect a system exhibiting charge-density wave (CDW) in its ground state. We consider a disordered Hubbard-Holstein model with a homogene…
Thermodynamic, magnetic and transport properties of the repulsive Hubbard model on the kagome lattice
Andressa R. Medeiros-Silva, Natanael C. Costa, Thereza Paiva
Over the past decades, magnetic frustration has been under intense debate due to its unusual properties. For instance, frustration in the kagome lattice suppresses long range spin…
Incommensurate charge density wave on multiband intermetallic systems exhibiting competing orders
Nei Lopes, Daniel Reyes, Natanael C. Costa +2
The appearance of an incommensurate charge density wave vector on multiband intermetallic systems presenting commensurate charge density wave (CDW) and sup…
Magnetism and metal-insulator transitions in the Rashba-Hubbard model
Welberth Kennedy, Sebastião dos Anjos Sousa Júnior, Natanael C. Costa +1
The nature of metal-insulator and magnetic transitions is still a subject under intense debate in condensed matter physics. Amongst the many possible mechanisms, the interplay betw…
Effect of Emitters on Quantum State Transfer in Coupled Cavity Arrays
Eli Baum, Amelia Broman, Trevor Clarke +8
Over the last decade, conditions for perfect state transfer in quantum spin chains have been discovered, and their experimental realizations addressed. In this paper, we consider a…
The 2D attractive Hubbard model and the BCS-BEC crossover
Rodrigo A. Fontenele, Natanael C. Costa, Raimundo R. dos Santos +1
Recent experiments with ultracold fermionic atoms in optical lattices have provided a tuneable and clean realization of the attractive Hubbard model (AHM). In view of this, several…
