Stable cosmological models driven by a free quantum scalar field
Claudio Dappiaggi, Klaus Fredenhagen, Nicola Pinamonti
In the mathematically rigorous analysis of semiclassical Einstein's equations, the renormalisation of the stress-energy tensor plays a crucial role. We address such a topic in the…
Cosmological horizons and reconstruction of quantum field theories
C. Dappiaggi, V. Moretti, N. Pinamonti
As a starting point, we state some relevant geometrical properties enjoyed by the cosmological horizon of a certain class of Friedmann-Robertson-Walker backgrounds. Those propertie…
Rigorous steps towards holography in asymptotically flat spacetimes
C. Dappiaggi, V. Moretti, N. Pinamonti
Scalar QFT on the boundary at null infinity of a general asymptotically flat 4D spacetime is constructed using the algebraic approach based on Weyl algebra associated to a…
Black hole entropy from classical Liouville theory
A. Giacomini, N. Pinamonti
In this article we compute the black hole entropy by finding a classical central charge of the Virasoro algebra of a Liouville theory using the Cardy formula. This is done by perfo…
