High-order connected moments expansion for the Rabi Hamiltonian
(De Gruyter, 2011-12-03)
We analyze the convergence properties of the connected moments expansion (CMX) for the Rabi Hamiltonian. To this end we calculate the moments and connected moments of the Hamiltonian operator to a sufficiently large order. ...
Estudo do modelo de Rabi no contexto de sistemas quânticos abertos
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Física - PPGF, 2009-01-27)
The Rabi Hamiltonian describes the interaction between a two-level atom and a single mode of the quantized electromagnetic field. In this work we study numerically and analytically the dynamics of the Rabi hamiltonian ...

Equação mestra microscópica para o modelo de Rabi
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Física - PPGF, 2013-02-27)
The Rabi model is the most complete one has to describe the interaction between radiation and matter. However, as it is difficult to obtain the exact solution to this model, many of recent atom-field studies have used the ...
Temporal dynamics in systems of qubits coupled to a bosonic mode
(Universidad de los AndesFísicaFacultad de CienciasDepartamento de Física, 2021-12-13)
Through the numerical study of the properties of the temporal evolution of a state of a spin-boson system in the deep strong coupling regime, a rich structure of probability collapses and revivals is discovered. By analyzing ...
Prospective Internet Running Under an In Band Full Duplex Scheme Based on Quantum Mechanics
(Institute of Electrical and Electronics EngineersPE, 2020-02-27)
Once quantum computer is running it is possible to expect that more quantum computers are interconnected in the same manner as the classical ones, so that Internet is seen as an imminent task in these advanced devices. As ...
Complex magnetic monopoles, geometric phases and quantum evolution in the vicinity of diabolic and exceptional points
(2008)
We consider the geometric phase and quantum tunneling in the vicinity of diabolic and exceptional points. We show that the geometric phase associated with the degeneracy points is defined by the flux of complex magnetic ...
