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…
Magnetism and charge order in the honeycomb lattice
Natanael C. Costa, Kazuhiro Seki, Sandro Sorella
Despite being relevant to better understand the properties of honeycomb-like systems, as graphene-based compounds, the electron-phonon interaction is commonly disregarded in theore…
Superconducting Kondo phase in an orbitally-separated bilayer
Sebastião dos Anjos Sousa-Júnior, José P. de Lima, Natanael C. Costa +1
The nature of superconductivity in heavy-fermion materials is a subject under intense debate, and controlling this many-body state is central for its eventual understanding. Here,…
Dynamical resilience to disorder: the dilute Hubbard model on the Lieb lattice
L. Oliveira-Lima, N. C. Costa, J. Pimentel de Lima +2
In itinerant systems, electron-electron interactions may lead to the formation of local magnetic moments and their effective exchange coupling, which in turn gives rise to long-ran…
Phase diagram of the two-dimensional Hubbard-Holstein model: enhancement of -wave pairing between charge and magnetic orders
Natanael C. Costa, Kazuhiro Seki, Seiji Yunoki +1
We investigate the role of electron-electron and electron-phonon interactions in strongly correlated systems by performing unbiased quantum Monte Carlo simulations in the square la…
