Upper quantum Lyapunov Exponent and Anosov relations for quantum systems driven by a classical flow
O. Sapin, H. R. Jauslin, S. Weigert
We generalize the definition of quantum Anosov properties and the related Lyapunov exponents to the case of quantum systems driven by a classical flow, i.e. skew-product systems. W…

Simple Minimal Informationally Complete Measurements for Qudits
Stefan Weigert
Simple minimal but informationally complete positive operator-valued measures are constructed out of the expectation-value representation for qudits. Upon suitable modification, th…

How to Test for Diagonalizability: The Discretized PT-Invariant Square-Well Potential
Stefan Weigert
Given a non-hermitean matrix M, the structure of its minimal polynomial encodes whether M is diagonalizable or not. This note will explain how to determine the minimal polynomial o…
