Classical chaotic signatures in Krylov space
Gastón F. Scialchi, Augusto J. Roncaglia, Diego A. Wisniacki
In recent years, Krylov space approaches have emerged as a useful framework for characterizing dynamical chaos in a wide variety of physical systems. However, the connection betwee…
Gaussian superpositions for bosonic encodings
Federico Centrone, Juan Pablo Paz, Augusto Roncaglia
Non-Gaussian bosonic states are ubiquitous in interacting light--matter systems, many-body platforms, and relativistic quantum field settings, but their quantitative characterizati…
Quantum-to-classical correspondence in Krylov complexity
Gastón F. Scialchi, Augusto J. Roncaglia, Diego A. Wisniacki
We study quantum-to-classical correspondence of the Krylov space for evolutions driven by unitary maps with a classical limit. This entails a proper definition of corresponding qua…
Purcell Enhancement and Suppression in Laser Cooling of Yb:YLF Nanocrystals in a Fabry-Pérot Microcavity
Lucas Mendicino, Franco Mayo, Christian Schmiegelow +1
We investigate the improvement of anti-Stokes laser cooling of a Yb:YLF nanocrystal in a Fabry-Pérot microcavity via the Purcell effect. Our analysis accounts for both the e…
Defining coherent states: why must they be eigenstates of the annihilation operator?
Juan Pablo Paz, Augusto J. Roncaglia
This is a pedagogical paper where we present a physically motivated approach to introduce the coherent states of a harmonic oscillator from which it is simple to rigorously derive…
Exploring quantum ergodicity of unitary evolution through the Krylov approach
Gastón F. Scialchi, Augusto J. Roncaglia, Carlos Pineda +1
In recent years, there has been growing interest in characterizing the complexity of quantum evolutions of interacting many-body systems. When a time-independent Hamiltonian govern…
