Tunnelling processes for Hadamard states through a 2+1 dimensional black hole and Hawking radiation
Francesco Bussola, Claudio Dappiaggi
We analyse the local behaviour of the two-point correlation function of a quantum state for a scalar field in a neighbourhood of a Killing horizon in a -dimensional spacetime,…

Ground state for a massive scalar field in BTZ spacetime with Robin boundary conditions
Francesco Bussola, Claudio Dappiaggi, Hugo R. C. Ferreira +1
We consider a real, massive scalar field in BTZ spacetime, a 2+1-dimensional black hole solution of the Einstein's field equations with a negative cosmological constant. First, we…
