Formulation of general dynamical invariants and their unitary relations for time-dependent three coupled quantum oscillators
Jeong Ryeol Choi
A general dynamical invariant operator for three coupled time-dependent oscillators is derived. Although the obtained invariant operator satisfies the Liouville-von Neumann equatio…

Formulation of general dynamical invariants and their unitary relations for time-dependent coupled quantum oscillators
Jeong Ryeol Choi
An exact invariant operator of time-dependent coupled oscillators is derived using the Liouville-von Neumann equation. The unitary relation between this invariant and the invariant…
