We develop a consistent semiclassical method to calculate the probability of topological soliton-antisoliton pair production in collisions of elementary particles. In our method one adds an auxiliary external field pulling the soliton and antisoliton in the opposite directions. This transforms the original scattering process into a Schwinger pair creation of the solitons induced by the particle collision. One describes the Schwinger process semiclassically and recovers the original scattering probability in the limit of vanishing external field. We illustrate the method in (1+1)-dimensional scalar field model where the suppression exponents of soliton-antisoliton production in the multiparticle and two-particle collisions are computed numerically.

  1. Thermal false vacuum decay near black holes is aspherical

    gr-qc 2026-08 conditional novelty 7.0 of 10

    False vacuum decay near a thermal Schwarzschild black hole is dominated by aspherical critical bubbles for intermediate sizes and by horizon-riding Fubini-Lipatov bounces for large sizes.

  2. Dynamics of nucleation in thermal phase transitions

    hep-th 2026-07 conditional novelty 7.0 of 10

    The thermal nucleation rate is the transition-state estimate multiplied by one minus the re-crossing probability, and oscillons make that correction large.
