Evolution of a kink-antikink ensemble in a quantum vacuum
Mainak Mukhopadhyay, Kohta Murase, Atsushi Naruko +1
We study the flat spacetime dynamics of a classical field configuration corresponding to an ensemble of sine-Gordon kinks and antikinks, semi-classically coupled to a quantum…

Cosmological scaling of precursor domain walls
Mainak Mukhopadhyay, Oriol Pujolas, George Zahariade
Domain wall (DW) networks have a large impact on cosmology and present interesting dynamics that can be controlled by various scaling regimes. In the first stage after spontaneous…

Semiclassical Backreaction: A Qualitative Assessment
Fabio van Dissel, George Zahariade
The backreaction of quantum degrees of freedom on classical backgrounds is a poorly understood topic in theoretical physics. Most often it is treated within the semiclassical appro…
