Coherent states of quantum linear rotator

Research output: Contribution to journalArticlepeer-review

Abstract

A system of coherent states is constructed for quantum linear rotator — a model for rotation of a diatomic molecule. The rotator in such a state possesses definite averages of orientation and angular momentum. Construction of coherent states is done in the framework of generalized Jordan–Schwinger approach to quantum angular momentum. The final definition of the coherent states involves operators which span the Lie algebra of metaplectic group Mp(4,R).
