Mean-field and fluctuation dynamics in off-resonant two-mode atom-field interactions
Luis Medina-Dozal, Alejandro R. Urzúa, Carlos A. González-Gutiérrez +1
We study a two-level system coupled to two quantized electromagnetic modes within the Jaynes-Cummings framework. While the single-mode model is exactly solvable due to its conserve…

A pedagogical derivation of the first-order effective Hamiltonian for the two-mode Jaynes-Cummings model
Alejandro R. Urzúa
This work presents a pedagogical and self-contained derivation of the first-order effective Hamiltonian for the two-mode Jaynes-Cummings model in the dispersive regime. A perturbat…

Construction of the Jaynes-Cummings interaction over the finite two-dimensional oscillator
Alejandro R. Urzúa
The interaction between a two-level atom and the finite two-dimensional oscillator in the Cartesian coordinate system is addressed. The construction of the coupling between the deg…
