Effects of next-nearest neighbor hopping on the pairing and critical temperatures of the attractive Hubbard model on a square lattice
Rodrigo A. Fontenele, Natanael C. Costa, Thereza Paiva +1
The attractive Hubbard model plays a paradigmatic role in the study of superconductivity (superfluidity) and has become directly realizable in ultracold atom experiments on optical…

Multifractal critical phase driven by coupling quasiperiodic systems to electromagnetic cavities
Thales F. Macedo, Julián Faúndez, Raimundo R. dos Santos +2
We theoretically investigate criticality and multifractal states in a one-dimensional Aubry-Andre-Harper model coupled to electromagnetic cavities. We focus on two specific cases w…
