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…

Exact Renormalisation Group Evolution of the Inflation Dynamics: Reconciling -Attractors with ACT
Jean Alexandre, Lucien Heurtier, Silvia Pla
We present a non-perturbative framework for the dynamics of slow-roll inflation that consistently incorporates quantum corrections, based on an alternative functional renormalisati…

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…
