Ultracold bosons in random lattice potentials
(Universidade Federal de São Carlos, UFSCar, Programa de Pós-Graduação em Física - PPGF, Câmpus São Carlos, 06/04/2023)The Bose-Hubbard model describes short-range interacting spinless bosons on a random lattice. This model is realized in ultracold atomic systems where quantum phase transitions can be observed. When loaded into a deep ... -
Turbulência de Ondas em condensados de Bose-Einstein
(Universidade Federal de São Carlos, UFSCar, Programa de Pós-Graduação em Física - PPGF, Câmpus São Carlos, 19/02/2018)In this work we used as a starting point the theory developed by Zakharov and Nazarenko for treating wave turbulence in systems with weak non linearity such as atomic Bose-Einstein condensates with low enough temperature ... -
Análise de fenômenos críticos no modelo Rock-Paper-Scissors
(Universidade Federal de São Carlos, UFSCar, Programa de Pós-Graduação em Física - PPGF, Câmpus São Carlos, 03/07/2019)This present work was developed with the purpose of analyzing critical phenomena in the Rock-Paper-Scissors model, consisting of three species and the empty site, initially distributed randomly in a square lattice, in ... -
Incompressible energy spectrum in atomic Bose-Einstein condensates: a weak wave turbulence theory approach
(Universidade Federal de São Carlos, UFSCar, Programa de Pós-Graduação em Física - PPGF, Câmpus São Carlos, 25/08/2022)Bose-Einstein condensates with their superfluidity property provide an interesting parallel to classical fluids. Due to the Kolmogorov spectrum of homogeneous turbulence the statistics of the incompressible velocity field ...
