Dear colleagues,
You are cordially invited to the online seminar of the Group for
Gravitation, Particles and Fields, which will be held on Friday, 1 April
2022 at 11:00 via the BigBlueButton platform (link is given below). Note
that this seminar is a continuation of the seminar presented last week.
The talk entitled
Entropy in Poincaré gauge theory: Hamiltonian approach
will be given by Branislav Cvetkovic (Institute of Physics Belgrade).
Abstract: Canonical generator G of local symmetries in Poincaré gauge
theory is constructed as an integral over a spatial section Σ of
spacetime. Its regularity (differentiability) on the phase space is
ensured by adding a suitable surface term, an integral over the boundary
of Σ at infinity, which represents the asymptotic canonical charge. For
black hole solutions, Σ has two boundaries, one at infinity and the
other at horizon. It is shown that the canonical charge at horizon
defines entropy, whereas the regularity of G implies the first law of
black hole thermodynamics.
