Colloquium

The LQP colloquium aims at communicating and promoting outstanding research in the context of local quantum physics, within the LQP community and beyond. The colloquium is held as a webinar and is intended to take place bi-annually.

The next event takes place March 16, 2022, 5pm CET (4pm UTC):

Feng Xu (UC Riverside): Rigorous results about entropy in QFT

Abstract: We will present some  rigorous results about Relative entropy and entropy in QFT, motivated in part by recent physicists work which however depends on heuristic arguments such as introducing cut off and using path integrals. In the particular case of CFT, we will discuss interesting relations between relative entropy, central charge and global dimension of conformal net, and asymptotics of entropy which comes from split property.
