From integrability to chaos: the quantum-classical correspondence in a triple well bosonic model
Erick R. Castro, Karin Wittmann W., Jorge Chávez-Carlos +3
In this work, we investigate the semiclassical limit of a simple bosonic quantum many-body system exhibiting both integrable and chaotic behavior. A classical Hamiltonian is derive…
Driving superconducting qubits into chaos
Jorge Chávez-Carlos, Miguel A. Prado Reynoso, Ignacio García-Mata +4
Kerr parametric oscillators are potential building blocks for fault-tolerant quantum computers. They can stabilize Kerr-cat qubits, which offer advantages toward the encoding and m…
Quantum-classical correspondence of a system of interacting bosons in a triple-well potential
E. R. Castro, Jorge Chavez-Carlos, I. Roditi +2
We study the quantum-classical correspondence of an experimentally accessible system of interacting bosons in a tilted triple-well potential. With the semiclassical analysis, we ge…
Experimental realization of the classical Dicke model
Mario A. Quiroz-Juárez, Jorge Chávez-Carlos, José L. Aragón +2
We report the experimental implementation of the Dicke model in the semiclassical approximation, which describes a large number of two-level atoms interacting with a single-mode el…
Positive quantum Lyapunov exponents in experimental systems with a regular classical limit
Saúl Pilatowsky-Cameo, Jorge Chávez-Carlos, Miguel A. Bastarrachea-Magnani +4
Quantum chaos refers to signatures of classical chaos found in the quantum domain. Recently, it has become common to equate the exponential behavior of out-of-time order correlator…
Quantum and Classical Lyapunov Exponents in Atom-Field Interaction Systems
Jorge Chávez-Carlos, B. López-del-Carpio, Miguel A. Bastarrachea-Magnani +4
The exponential growth of the out-of-time-ordered correlator (OTOC) has been proposed as a quantum signature of classical chaos. The growth rate is expected to coincide with the cl…
Analytical description of the survival probability of coherent states in regular regimes
Sergio Lerma-Hernández, Jorge Chávez-Carlos, Miguel A. Bastarrachea-Magnani +2
Using coherent states as initial states, we investigate the quantum dynamics of the Lipkin-Meshkov-Glick (LMG) and Dicke models in the semi-classical limit. They are representative…
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…
