We apply the recently discovered classical-quantum correspondence (CQC) to study the quantum evaporation of breathers in an extended sine-Gordon model. We present numerical results for the decay rate of the breather as a function of the coupling strength in the model. This is a complete treatment of the backreaction of quantum radiation on the classical dynamics of oscillons.

Oscillon Floquet Modes and the Operators that Excite Them
hep-th 2026-07 conditional novelty 6.0

Relativistic Floquet modes of the oscillon are expressed in elementary functions, and their quantum creation/annihilation operators are shown to satisfy the oscillator algebra at the computed order.
