Stargenfunctions, generally parametrized systems and a causal formulation of phase space quantum mechanics
Nuno Costa Dias, Joao Nuno Prata
We address the deformation quantization of generally parametrized systems displaying a natural time variable. The purpose of this exercise is twofold: first, to illustrate through…

Comment on "On infinite walls in deformation quantization"
Nuno Costa Dias, Joao Nuno Prata
We discuss a recent method proposed by Kryukov and Walton to address boundary-value problems in the context of deformation quantization. We compare their method with our own approa…

Deformation Quantization and Wigner Functions
Nuno Costa Dias, Joao Nuno Prata
We review the Weyl-Wigner formulation of quantum mechanics in phase space. We discuss the concept of Narcowich-Wigner spectrum and use it to state necessary and sufficient conditio…
