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…

Formation of defects associated with both spontaneous and explicit symmetry breaking
Kohei Fujikura, Mairi Sakellariadou, Michiru Uwabo-Niibo +1
We discuss formation of cosmic strings associated with a spontaneously broken approximate symmetry by performing classical field-theoretical simulations. An original …
