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…
Time irreversibility and entropy production in non-Hermitian Model A field theories
Matthias Carosi, Ot Garcés, Adrià Garcés +1
We develop a systematic framework to quantify irreversibility in scalar Model A field theories with a generic non-Hermitian term driving the dynamics. Using the stochastic path-int…
On equivalent methods for functional determinants
Matthias Carosi
Computing functional determinants of differential operators is central to any field-theoretical calculation relying on a saddle-point expansion. A variety of approaches is availabl…
Bubble wall dynamics from nonequilibrium quantum field theory
Wen-Yuan Ai, Matthias Carosi, Bjorn Garbrecht +2
We derive the coupled dynamics between the bubble wall and the plasma from first principles using nonequilibrium quantum field theory. The commonly used equation of motion of the b…
False vacuum decay beyond the quadratic approximation: summation of non-local self-energies
Matthias Carosi, Björn Garbrecht
Using the 2PI effective action formalism, we study false vacuum decay beyond the quadratic approximation of the path integral. We derive a coupled system of equations for the bounc…
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…
