Deformation Quantization of a Certain Type of Open Systems
Florian Becher, Nikolai Neumaier, Stefan Waldmann
We give an approach to open quantum systems based on formal deformation quantization. It is shown that classical open systems of a certain type can be systematically quantized into…

Complete Positivity of Rieffel's Deformation Quantization by Actions of
Daniel Kaschek, Nikolai Neumaier, Stefan Waldmann
In this paper we consider C*-algebraic deformations a la Rieffel and show that every state of the undeformed algebra can be deformed into a state of the deformed algebra in the sen…
