Kinks bounded by fermions
Ilya Perapechka, Yakov Shnir
We present and study new mechanism of interaction between the solitons based on the exchange interaction mediated by the localized fermion states. As particular examples, we consid…
Fermions on the kink revisited
V. Klimashonok, I. Perapechka, Ya. Shnir
We study fermion modes localized on the kink in the 1+1 dimensional model, coupled to the Dirac fermions with backreaction. Using numerical methods we construct self-consiste…
Asymptotically flat spinning scalar, Dirac and Proca stars
C. Herdeiro, I. Perapechka, E. Radu +1
Einstein's gravity minimally coupled to free, massive, classical fundamental fields admits particle-like solutions. These are asymptotically flat, everywhere non-singular configura…
Kerr black holes with synchronised scalar hair and boson stars in the Einstein-Friedberg-Lee-Sirlin model
J Kunz, I Perapechka, Ya Shnir
We study a new family of self-gravitating axially-symmetric, rotating boson stars in the two-component Friedberg-Lee-Sirlin model minimally coupled to Einstein gravity in four spac…
Kerr black holes with parity-odd scalar hair
J. Kunz, I. Perapechka, Ya. Shnir
We study Kerr black holes with synchronised non-trivial parity-odd massive scalar hair in four dimensional asymptotically flat space-time. These axially symmetric stationary spinni…
Magnetic Skyrmions coupled to fermions
I. Perapechka, Ya. Shnir
The index theorem implies that there are fermionic states localized on a soliton. Presence of these modes may significantly alter the pattern of interaction between the solitons. A…
