TLDR
In this article, the coherent states of Sp(2d,R), corresponding to the positive discrete series irreducible representations encountered in physical applications, are analyzed in detail with special emphasis on Sp(4,R) and Sp(6,R).Abstract:
In the present series of papers, the coherent states of Sp(2d,R), corresponding to the positive discrete series irreducible representations 〈λd+n/2,...,λ1+n/2〉 encountered in physical applications, are analyzed in detail with special emphasis on those of Sp(4,R) and Sp(6,R). The present paper discusses the unitary‐operator coherent states, as defined by Klauder, Perelomov, and Gilmore. These states are parametrized by the points of the coset space Sp(2d,R)/H, where H is the stability group of the Sp(2d,R) irreducible representation lowest weight state, chosen as the reference state, and depends upon the relative values of λ1,...,λd, subject to the conditions λ1≥λ2≥ ⋅ ⋅ ⋅ ≥λd≥0. A parametrization of Sp(2d,R)/H corresponding to a factorization of the latter into a product of coset spaces Sp(2d,R)/U(d) and U(d)/H is chosen. The overlap of two coherent states is calculated, the action of the Sp(2d,R) generators on the coherent states is determined, and the explicit form of the unity resolution relation satisf...read more

Analytic representations in quantum mechanics
TL;DR: In this article, various Euclidean, hyperbolic and elliptic analytic representations of the harmonic oscillator are discussed and relations among them are discussed, and the general theory that relates the growth of analytic functions with the density of their zeros is applied to Bargmann functions and leads to theorems on the completeness of sequences of Glauber coherent states.

TL;DR: In this article, the Riemann ellipsoid equations of motion are proven to constitute a Hamiltonian dynamical system, and the phase space is a co-adjoint orbit of the Lie group GCM(3), which is generated by the linear group Gl(3, R) and the inertia tensor.

The Quantum Theory of Optical Coherence
