Quantum tunnelling, real-time dynamics and Picard-Lefschetz thimbles
(Peer reviewed; Journal article, 2019-11)We follow up the work, where in light of the Picard-Lefschetz thimble approach, we split up the real-time path integral into two parts: the initial density matrix part which can be represented via an ensemble of initial ... -
Simulations of a bubble wall interacting with an electroweak plasma
(Peer reviewed; Journal article, 2021-02)We perform large-scale real-time simulations of a bubble wall sweeping through an out-of-equilibrium plasma. The scenario we have in mind is the electroweak phase transition, which may be first order in extensions of the ... -
Stable solvers for real-time Complex Langevin
(Peer reviewed; Journal article, 2021-08)This study explores the potential of modern implicit solvers for stochastic partial differential equations in the simulation of real-time complex Langevin dynamics. Not only do these methods offer asymptotic stability, ...
