Compact baby skyrmions

Understand

For the baby Skyrme model with a specific potential, compacton solutions, i.e., configurations with a compact support and parabolic approach to the vacuum, are derived.

• Specifically, in the non-topological sector, we find spinning Q-balls and Q-shells, as well as peakons.
• Moreover, we obtain compact baby skyrmions with non-trivial topological charge.
• All these solutions may form stable multi-soliton configurations provided they are sufficiently separated.
