Decay and lifetime of oscillons coupled to an external scalar field: Insights from instability band analysis
Siyao Li, Masahide Yamaguchi, Ying-li Zhang
Oscillons are long-lived, spherically symmetric solitons that can arise in real scalar field theories with potentials shallower than quadratic ones. They are considered to form via…

Oscillon decay via parametric resonance: the case of three-point scalar interactions
Siyao Li
We investigate the decay dynamics of oscillons through interactions with an external scalar field. To examine how robust the decay dynamics of oscillons via parametric resonance we…
