Exact Gaussian Entanglement Dynamics and Initial-State Control in Coupled Parametric Oscillators
Roberto Bernal-Jaquez, Hector H. Hernandez-Hernandez, Alexander Schaum +1
We study two bilinearly coupled harmonic oscillators driven by a common time-dependent spring. A fixed normal-mode transformation reduces the pair to two parametric oscillators, ea…

Semiclassical effective description of a quantum particle on a sphere with non-central potential
Guillermo Chacon-Acosta, H. Hernandez-Hernandez, J. Ruvalcaba-Rascon
We develop a semiclassical framework for studying quantum particles constrained to curved surfaces using the momentous quantum mechanics formalism, which extends classical phase-sp…
