Time dependent coupled harmonic oscillators
Alejandro R. Urzúa, Héctor M. Moya-Cessa, Irán Ramos-Prieto +1
We show that, by using the quantum orthogonal functions invariant, we are able to solve a coupled of time dependent harmonic oscillators where all the time dependent frequencies ar…
Quantum derivation of Manley Rowe type relations
M. Fernández Guasti, H. Moya-Cessa
The Ermakov Lewis quantum invariant for the time dependent harmonic oscillator is expressed in terms of number and phase operators. The identification of these variables is made in…
Amplitude and phase representation of quantum invariants for the time dependent harmonic oscillator
M. Fernandez Guasti, H. Moya-Cessa
The correspondence between classical and quantum invariants is established. The Ermakov Lewis quantum invariant of the time dependent harmonic oscillator is translated from the coo…
