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…
Baryogenesis and EDMs in the 2HDM+CS
Björn Garbrecht, Edward Wang
We perform the first joint analysis of baryogenesis from initial Higgs charges (also called Higgsogenesis) and EDMs in a model with two Higgs doublets, a complex scalar and a Major…
Instantons meet resonances: Unifying two seemingly distinct approaches to quantum tunneling
Björn Garbrecht, Nils Wagner
In the study of quantum-mechanical tunneling processes, numerous approaches have been developed to determine the decay rate of states initially confined within a metastable potenti…
Reply to "Clearing up the Strong problem"
Wen-Yuan Ai, Björn Garbrecht, Carlos Tamarit
The conservation of in QCD has been shown to follow from a careful treatment of the path integral and canonical quantization in arXiv:2001.07152 and arXiv:2403.00747. Here, we…
Path integral analysis of Schrödinger-type eigenvalue problems in the complex plane: Establishing the relation between instantons and resonant states
Björn Garbrecht, Nils Wagner
Schrödinger-type eigenvalue problems are ubiquitous in theoretical physics, with quantum-mechanical applications typically confined to cases for which the eigenfunctions are requir…
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…
