SUMMARY:AG Mathematische Physik\, Markus Fröb (Leipzig): How to compu
 te modular Hamiltonians
UID:5384d1e5-ac30-4c24-b975-ada02f6448ca
DESCRIPTION:Markus Fröb (Leipzig) How to compute modular Hamiltonians
  Abstract: The Tomita-Takesaki theory of modular automorphisms of von 
 Neumann algebras has attracted renewed interest in recent years in con
 nection with the definition of entropies in quantum field theory. I wi
 ll present a short introduction to the theory\, in which the main obje
 ct of interest is the modular Hamiltonian. I then explain how one can 
 compute this Hamiltonian explicitly in various situations\, in particu
 lar for relativistic fermions in 1+1 dimensions. Based on arXiv:2312.0
 4629\, arXiv:2406.19360\, arXiv:2411.09696 and arXiv:2501.09669.
