Ground state of fermions in quasi-1D honeycomb optical lattices
(Universidad Nacional de ColombiaBogotá - Ciencias - Maestría en Ciencias - FísicaFacultad de CienciasBogotá, ColombiaUniversidad Nacional de Colombia - Sede Bogotá, 2022)
Lattice models (tight-binding) for many-body systems give a good theoretical
and experimental framework to study quantum phase transitions presented in several
strongly correlated materials at low temperature. In general, ...
Topological Kondo insulators in one dimension: Continuous Haldane-type ground-state evolution from the strongly interacting to the noninteracting limit
(American Physical Society, 2017-08)
We study, by means of the density-matrix renormalization group (DMRG) technique, the evolution of the ground state in a one-dimensional topological insulator, from the noninteracting to the strongly interacting limit, where ...

Mean-field phase diagram of the extended Bose-Hubbard model of many-body cavity quantum electrodynamics
(American Physical Society, 2019-04-30)
We investigate the mean-field phase diagram of the Bose-Hubbard model with infinite-range interactions in two dimensions. This model describes ultracold bosonic atoms confined by a twodimensional optical lattice and ...
Estudo do modelo de Hubbard bidimensional não homogêneo via teoria do funcional da densidade
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Física - PPGFCâmpus São Carlos, 2021-07-14)
We implemented the DFT calculation through the Kohn-Sham formalism adapted by the methodology μ-BALDA for the inhomogeneous two-dimensional Hubbard model, which is also implemented experimentally on an ultra-cold atom traps ...
