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…
