Quantum scarring in a spin-boson system: fundamental families of periodic orbits
Saúl Pilatowsky-Cameo, David Villaseñor, Miguel A. Bastarrachea-Magnani +3
As the name indicates, a periodic orbit is a solution for a dynamical system that repeats itself in time. In the regular regime, periodic orbits are stable, while in the chaotic re…
Ubiquitous quantum scarring does not prevent ergodicity
Saúl Pilatowsky-Cameo, David Villaseñor, Miguel A. Bastarrachea-Magnani +3
In a classically chaotic system that is ergodic, any trajectory will be arbitrarily close to any point of the available phase space after a long time, filling it uniformly. Using B…
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…
Dynamical signatures of quantum chaos and relaxation timescales in a spin-boson system
S. Lerma-Hernández, D. Villaseñor, M. A. Bastarrachea-Magnani +3
Quantum systems whose classical counterparts are chaotic typically have highly correlated eigenvalues and level statistics that coincide with those from ensembles of full random ma…
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…
Collisional Statistics and Dynamics of 2D Hard-Disk Systems: From Fluid to Solid
Alessandro Taloni, Yasmine Meroz, Adrián Huerta
We perform extensive MD simulations of two-dimensional systems of hard disks, focusing on the \emph{on}-collision statistical properties. We analyze the distribution functions of v…
