Near-BPS baby Skyrmions with Gaussian tails
Sven Bjarke Gudnason, Marco Barsanti, Stefano Bolognesi
We consider the baby Skyrme model in a physically motivated limit of reaching the restricted or BPS baby Skyrme model, which is a model that enjoys area-preserving diffeomorphism i…

Analytic Baby Skyrmions at Finite Density
Marco Barsanti, Stefano Bolognesi, Fabrizio Canfora +1
We introduce a consistent ansatz for the baby Skyrme model in (2+1)-dimensions which is able to reduce the complete set of field equations to just one equation for the profile func…

Near-BPS baby Skyrmions
Sven Bjarke Gudnason, Marco Barsanti, Stefano Bolognesi
We consider the baby-Skyrme model in the regime close to the so-called restricted baby-Skyrme model, which is a BPS model with area-preserving diffeomorphism invariance. The pertur…
