Regularity and chaos in cavity QED
M. A. Bastarrachea-Magnani, B. López-del-Carpio, J. Chávez-Carlos +2
The interaction of a quantized electromagnetic field in a cavity with a set of two-level atoms inside can be described with algebraic Hamiltonians of increasing complexity, from th…
Adiabatic invariants for the regular region of the Dicke model
M. A. Bastarrachea-Magnani, A. Relaño, S. Lerma-Hernández +3
Adiabatic invariants are introduced and shown to provide an approximate second integral of motion for the non-integrable Dicke model, in the energy region where the system exhibits…
Classical chaos in atom-field systems
J. Chávez-Carlos, M. A. Bastarrachea-Magnani, S. Lerma-Hernández +1
The relation between the onset of chaos and critical phenomena, like Quantum Phase Transitions (QPT) and Excited-State Quantum Phase transitions (ESQPT), is analyzed for atom-field…
