The restricted isometry property for time-frequency structured random matrices
Götz E. Pfander, Holger Rauhut, Joel A. Tropp
We establish the restricted isometry property for finite dimensional Gabor systems, that is, for families of time--frequency shifts of a randomly chosen window function. We show th…

From joint convexity of quantum relative entropy to a concavity theorem of Lieb
Joel A. Tropp
This note provides a succinct proof of a 1973 theorem of Lieb that establishes the concavity of a certain trace function. The development relies on a deep result from quantum infor…
