Sparse Gabor representations of metaplectic operators: controlled exponential decay and Schrödinger confinement
Elena Cordero, Gianluca Giacchi, Edoardo Pucci +1
Motivated by the phase space analysis of Schrödinger evolution operators, in this paper we investigate how metaplectic operators are approximately diagonalized along the correspon…

Wave packet analysis of semigroups generated by quadratic differential operators
S. Ivan Trapasso
We perform a phase space analysis of evolution equations associated with the Weyl quantization of a complex quadratic form on with non-positi…
