Mass and entropy of asymptotically flat eternal quantum black holes in 2D
Jean Alexandre, Eleni-Alexandra Kontou, Diego Pardo Santos +2
Semi-classical dilaton gravity in (1+1)-dimensions remains one of the only arenas where quantum black holes can be exactly constructed, fully accounting for backreaction due to qua…

Mapping 1+1-dimensional black hole thermodynamics to finite volume effects
Jean Alexandre, Drew Backhouse, Eleni-Alexandra Kontou +2
Both black hole thermodynamics and finite volume effects in quantum field theory violate the null energy condition. Motivated by this, we compare thermodynamic features between two…

How negative can null energy be in large N CFTs?
Jackson R. Fliss, Ben Freivogel, Eleni-Alexandra Kontou +1
Smeared null energy has been shown to be bounded from below for free minimally coupled quantum field theories. This is not the case for conformally coupled free bosonic theories wh…
