Metaplectic sheets and caustic traversals in the Weyl representation
Alfredo M. Ozorio de Almeida, Gert-Ludwig Ingold
The quantum Hamiltonian generates in time a family of evolution operators. Continuity of this family holds within any choice of representation and, in particular, for the Weyl prop…
A variational principle for actions on symmetric symplectic spaces
Pedro de M. Rios, A. Ozorio de Almeida
We present a definition of generating functions of canonical relations, which are real functions on symmetric symplectic spaces, discussing some conditions for the presence of caus…
On the propagation of semiclassical Wigner functions
Pedro P. de M. Rios, A. M. Ozorio de Almeida
We establish the difference between the propagation of semiclassical Wigner functions and classical Liouville propagation. First we re-discuss the semiclassical limit for the propa…
