SUMMARY:Janik Rausch (HU Berlin) - 
DESCRIPTION:Speaker: Janik Rausch (HU Berlin)\n\nTitle: Thermal stress-ene
 rgy tensor for massless quantum fields in Kerr-Newman spacetime\n\nAbstrac
 t:\nWe investigated massless quantum fields in a rotational global equilib
 rium state on a Kerr-Newman black hole background. In particular\, we cons
 idered the analytic part of the thermal expectation value of the stress-en
 ergy tensor which has recently been conjectured to be independent of the u
 nderlying spacetime. We attempted to calculate this analytic part starting
  from a general expansion built from geometric quantities. In the Kerr lim
 it we were able to fix 58 out of 59 expansion coefficients\, and in the Sc
 hwarzschild limit we obtained a fully determined result that is consistent
  with the literature.
