Matter Sourced Bubble Nucleation in the Asymmetron Scalar-Tensor Theory
Usama Syed Aqeel, Clare Burrage, Oliver Gould +1
We investigate how matter density distributions affect thin-wall bubble formation in the asymmetron mechanism, a scalar-tensor theory with a universal coupling to matter and explic…

Oscillons and bubbles in -ball dynamics
D. Canillas Martínez, P. Dorey, T. Romańczukiewicz +3
We show that, in the thin-wall regime, -ball--anti--ball collisions reveal chaotic behaviour. This is explained by the resonant energy transfer mechanism triggered by the int…
