Gravitating Skyrmions with localized fermions
Vladimir Dzhunushaliev, Vladimir Folomeev, Jutta Kunz +1
We consider self-gravitating Skyrmions in the presence of Dirac fermions, that carry spin and isospin. By varying the gravitational and the Yukawa coupling constants, we investigat…
Hairy dyonic Reissner-Nordström black holes in an Einstein-Maxwell-Friedberg-Lee-Sirlin type model
Jutta Kunz, Victor Loiko, Yakov Shnir
We construct spherically symmetric dyonic black holes in a generalized Maxwell-Friedberg-Lee-Sirlin type model with a complex scalar doublet and a symmetry breaking potential {for…
Fermion states localized on a self-gravitating Skyrmion
Vladimir Dzhunushaliev, Vladimir Folomeev, Jutta Kunz +1
We investigate self-gravitating solutions of the Einstein-Skyrme theory coupled to spin-isospin Dirac fermions and consider the dependence of the spectral flow on the effective gra…
