Empirical plunge profiles of time-frequency localization operators
Simon Halvdansson
For time-frequency localization operators, related to the short-time Fourier transform, with symbol , we work out the exact large eigenvalue behavior for rotationally inva…

Measure-operator convolutions and applications to mixed-state Gabor multipliers
Hans G. Feichtinger, Simon Halvdansson, Franz Luef
For the Weyl-Heisenberg group, convolutions between functions and operators were defined by Werner as a part of a framework called quantum harmonic analysis. We show how recent res…
