Unified theory of oscillons and modes
F. Blaschke, T. Romanczukiewicz, K. Slawinska +1
We show that an oscillon can be understood as a localized discrete resonant (non-normalizable) mode. Specifically, oscillon in the vacuum arises from the threshold mode, which beca…
Oscillons in the broken vacuum and global vortex annihilation
D. Canillas Martínez, A. González-Parra, D. Miguélez-Caballero +1
In contrast to the complex model, vortex-antivortex collisions in the complex theory reveal a resonant structure due to the existence of a remarkably stable, long-lived…
The Universal Floquet Modes of (Quasi)-Breathers and Oscillons
Jarah Evslin, Tomasz Romańczukiewicz, Katarzyna Slawińska +1
Just as linearized perturbations of time-independent configurations can be decomposed into normal modes, those of periodic systems can be decomposed into Floquet modes, which each…
Normal Modes of the Small-Amplitude Oscillon
Jarah Evslin, Tomasz Romanczukiewicz, Katarzyna Slawinska +1
Consider a classical (1+1)-dimensional oscillon of small amplitude . To all orders in , the oscillon solution is exactly periodic. We study small perturbations of such period…
Quantum Oscillons May be Long-Lived
Jarah Evslin, Tomasz Romańczukiewicz, Andrzej Wereszczyński
Hertzberg has constructed a quantum oscillon that decays into pairs of relativistic mesons with a power much greater than the radiation from classical oscillon decay. This result i…
Fermionic spectral walls in kink collisions
João G. F. Campos, Azadeh Mohammadi, Jose M. Queiruga +2
We show that a spectral wall, i.e., an obstacle in the dynamics of a bosonic soliton, which arises due to the transition of a normal mode into the continuum spectrum, exists after…
Spectral Walls at One Loop
Jarah Evslin, Chris Halcrow, Tomasz Romanczukiewicz +1
A spectral wall is a surface in a moduli space of classically BPS solitons where an internal excitation crosses the continuum mass threshold. It has recently been shown that spectr…
