Baby Skyrme model and fermionic zero modes

Understand

In this work we investigate some features of the fermionic sector of the supersymmetric version of the baby Skyrme model.

• We find that, in the background of BPS compact Skyrmions, fermionic zero modes are confined to the defect core.
• Further, we show that, while three SUSY generators are broken in the defect core, SUSY is completely restored outside.
• We study also the effect of a D-term deformation of the model.
