Abstract
Recently it was demonstrated that magnon condensation in the trap
exhibits the phenomenon of self-localization. When
the number of magnons in the textural trap increases, they drastically modify
the profile of the gap and highly increase its size. The trap gradually
transforms from the initial harmonic one to the box with walls almost
impenetrable for magnons. The resulting texture-free "cavity" filled by the
magnon condensate wave function becomes the bosonic analog of the MIT bag, in
which hadron is seen as a cavity surrounded by the QCD vacuum, in which the
free quarks are confined in the ground or excited state. Here, we consider
the bosonic analog of the MIT bag with quarks on the ground and excited
levels.
