Environment-controlled Floquet-state paramagnetism
Onno R. Diermann, Heinz-Jürgen Schmidt, Jürgen Schnack +1
We study the response of ideal spin systems which are interacting with both a strong oscillating magnetic field, and a thermal environment, to a weak probing magnetic field. We dem…

Conditional action and quantum versions of Maxwell's demon
Heinz-Jürgen Schmidt
We propose a new way of looking at the quantum Maxwell's demon problem in terms of conditional action. A "conditional action" on a system is a unitary time evolution, selected acco…

Sequential measurements and entropy
Heinz-Jürgen Schmidt, Jochen Gemmer
We sketch applications of the so-called J-equation to quantum information theory concerning fundamental properties of the von Neumann entropy. The J-equation has recently be propos…
