Classical and quantum dynamics of a particle confined in a paraboloidal cavity
Ángel E. Reyna-Cruz, Julio C. Gutiérrez-Vega
We present a classical and quantum analysis of a particle confined in a three-dimensional paraboloidal cavity formed by two confocal paraboloids. Classically, the system is integra…

Spectral analysis of the Koopman operator as a framework for recovering Hamiltonian parameters in open quantum systems
Jorge E. Pérez-García, Carlos Colchero, Julio C. Gutiérrez-Vega
Accurate identification of Hamiltonian parameters is essential for modeling and controlling open quantum systems. In this work, we demonstrate that the multichannel Hankel alternat…
