Quadrature fluctuation energy, effective Hamiltonians, quasi-particle modes and quantum phase transitions in the Rabi and Dicke models
(Research gate, 2017)
The main purpose of this article is to provide a simple physically motivated exact analytical procedure
for determining effective Rabi and Dicke Hamiltonians, which have so far posed serious challenges in
studies of ...
Polariton and anti-polariton qubits in the Rabi model
(Research gate, 2017)
This paper presents a precise algebraic and physical framework for studying the dynamics and practical
applications of the quantum Rabi model. We redefine the quantum Rabi interaction in terms of polariton
and anti-polariton ...
Conserved excitation number and U(1)-symmetry operators for the anti-rotating (anti-Jaynes-Cummings) term of the Rabi Hamiltonian
(Research gate, 2017)
+ hω0sz+ hg (ˆa+ ˆa†)(s++ s−)(1a) where ω, ˆa, ˆa† are the quantized field mode angular frequency, annihilation and creation operators, while ω0, sz, s+, s− are the atomic state transition angular frequency and operators. ...
