Abstract:
Fundamental symmetries of physics such as C,P,T are central for our understanding of nature and have usually been tested in the framework of high energy physics. In the lecture we shall outline the general foundations and the consequences in the realm of molecular physics and high resolution spectroscopy of chiral molecules. We shall present the current status of the theory of molecular parity violation, where we have recently discovered in new theoretical calculations order of magnitude larger effects than previously accepted. We shall discuss the role of these effects in the evolution of biomolecular homochirality. Finally we shall present the current experimental approaches to tests of molecular parity violation as well as the possibilty of experimental tests of CPT invariance of ultrahigh sensitivity by the spectroscopy of chiral molecules.

Background reading are two recent reviews, where further refences can be found
