Effective action approach to the dynamical map
Marek Lewicki, Luca Smaldone
The dynamical map represents a fundamental concept in quantum field theory, providing a solution of the field equations in the Fock space of asymptotic fields. In this paper, we sh…

Generalised escape paths for dynamical tunneling in QFT
Luc Darmé, Joerg Jaeckel, Marek Lewicki
We present a formalism based on the functional Schrödinger equation to analyse time-dependent tunneling in quantum field theory at the semi-classical level. The full problem is red…

Towards the fate of the oscillating false vacuum
Luc Darmé, Joerg Jaeckel, Marek Lewicki
Motivated by cosmological examples we study quantum field theoretical tunnelling from an initial state where the "classical field", i.e. the vacuum expectation value of the field o…
