We study scalar bubble collisions in first-order phase transitions focusing
on the relativistic limit. We propose ‘trapping equation’ which describes the
wall behavior after collision, and test it with numerical simulations in
several setups. We also examine the energy dynamics after collision and discuss
its implications to gravitational wave production.
