Polyanalytic Toeplitz operators: isomorphisms, symbolic calculus and approximation of Weyl operators
Johannes Keller, Franz Luef
We discuss an extension of Toeplitz quantization based on polyanalytic functions. We derive isomorphism theorem for polyanalytic Toeplitz operators between weighted Sobolev-Fock sp…

Quantum expectations via spectrograms
Johannes Keller, Caroline Lasser, Tomoki Ohsawa
We discuss a new phase space method for the computation of quantum expectation values in the high frequency regime. Instead of representing a wavefunction by its Wigner function, w…
