Chaos-based Potentials in the One-dimensional Tight-binding Model Probed by the Inverse Participation Ratio
Weslley Florentino de Oliveira, Giancarlo Queiroz Pellegrino
Chaos-based potentials are defined and implemented in the one-dimensional tight-binding model as a way of simulating disorder-controlled crystalline lattices. In this setting, diso…
Quantum phase transition in an effective three-mode model of interacting bosons
H. M. Frazão, J. G. Peixoto de Faria, G. Q. Pellegrino +1
In this work we study an effective three-mode model describing interacting bosons. These bosons can be considered as exciton-polaritons in a semiconductor microcavity at the magic…
Analysis of quantum phase transition in some different Curie-Weiss models: a unified approach
Carla Maria Pontes Carneiro, Giancarlo Queiroz Pellegrino
A unified approach to the analysis of quantum phase transitions in some different Curie-Weiss models is proposed such that they are treated and analyzed under the same general sche…
Application of an inverse Holstein-Primakoff transformation to the Jaynes-Cummings model
Carla Maria Pontes Carneiro, Giancarlo Queiroz Pellegrino
A modification of the Holstein-Primakoff transformation is proposed such that creation and annihilation operators for a bosonic field are rewritten as operators of a algebr…
