Physics

I will briefly review properties of quasi-hermitian (PT-symmetric) theories in the context of simple QM examples, especially the model V = exp(2ix), as well as some generalizations. I will then describe some preliminary work on field theory...

This talk briefly reviews the basic ideas of `t Hooft's derivation of quantum from classical physics. In the core part of the talk I describe new results with Massimo Blasone and Hagen Kleinert in which we show how `t Hooft's program can be phrased...
