On the relaxation dynamics of non-equilibrium quantum systems
Matthias Carosi, Björn Garbrecht, Silvia Pla +2
We investigate the relaxation of an approximately conserved charge in interacting quantum systems close to local equilibrium. To this end, we provide a pedagogical review of Zubare…
Wilsonian Cosmology: de Sitter (in)Stability
Jean Alexandre, Lucien Heurtier, Silvia Pla
We develop a (Wilsonian) functional-renormalisation-group framework for scalar cosmology in which quantum fluctuations of a scalar field are coarse-grained on cosmological spacelik…
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…
Double-well instantons in finite volume
Wen-Yuan Ai, Jean Alexandre, Matthias Carosi +2
Assuming a toroidal space with finite volume, we derive analytically the full one-loop vacuum energy for a scalar field tunnelling between two degenerate vacua, taking into account…
