Application of Tripartite Entangled State Representation in Solving the Dynamics of a Kind of Three Coupled Oscillators
Pang Qian-Jun
Abstract
We study the eigenstate problem of a kind of three coupled oscillators in a new quantum mechanical representation composed by the spontaneous eigenvectors ⟨ p , q 2 , q 3 | for three operators ( p 1 + p 2 + p 3 ), ( x 3 − x 2 ), and ( x 3 − x 1 ). The eigenvalues and eigenvectors of the Hamiltonian are obtained. With the same method, the eigenstate problem of a generalized three-coupled oscillator Hamiltonian is studied, which has never been studied before.
