Axiverse Strings Resolved
Rudin Petrossian-Byrne, Giovanni Villadoro
Axiverse cosmic strings are resolved by non-perturbative string states with large tension. We show how, in some regions of moduli space, they dissolve into low-tension configuratio…
Open String Axiverse
Rudin Petrossian-Byrne, Giovanni Villadoro
Localized charged fields are a general feature of many realistic string compactifications. In four dimensions they can lead to a multitude of perturbatively-exact global symmetries…
Axion Interactions with Domain and Bubble Walls
Isabel Garcia Garcia, Rudin Petrossian-Byrne
We show that interactions between axion-like particles (ALPs) and co-dimension one defects, such as phase-transition bubble walls and solitonic domain walls, can lead to important…
NLO friction in symmetry restoring phase transitions
Aleksandr Azatov, Giulio Barni, Rudin Petrossian-Byrne
Interactions between bubbles/domain walls and the surrounding medium are a topic of active research, particularly as they apply to friction effects on accelerated expansion during…
Quantisation Across Bubble Walls and Friction
Aleksandr Azatov, Giulio Barni, Rudin Petrossian-Byrne +1
We quantise from first principles field theories living on the background of a bubble wall in the planar limit with particular focus on the case of spontaneous breaking of gauge sy…
Reflections on Bubble Walls
Isabel Garcia Garcia, Giacomo Koszegi, Rudin Petrossian-Byrne
We discuss the dynamics of expanding bubble walls in the presence of massive dark photons whose mass changes as they cross the wall. For sufficiently thin walls, we show that there…
