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 …

Interactions between several types of cosmic strings
Kohei Fujikura, Siyao Li, Masahide Yamaguchi
We study the interaction of several types of static straight cosmic strings, including local strings, global strings, and bosonic superconducting strings with and without magnetic…
