Looking beyond the Thermal Horizon: Hidden Symmetries in Chiral Models
B. Schroer, H. -W. Wiesbrock
In thermal states of chiral theories, as recently investigated by H.-J. Borchers and J. Yngvason, there exists a rich group of hidden symmetries. Here we show that this leads to a…

Modular Theory and Geometry
B. Schroer, H. -W. Wiesbock
In this letter we present some new results on modular theory and its application in quantum field theory. In doing this we develop some new proposals how to generalize concepts of…
