Fermions coupled to Skyrmions on S 3
نویسنده
چکیده
This paper discusses Skyrmions on the 3-sphere coupled to fermions. The resulting Dirac equation commutes with a generalized angular momentum G. For G = 0 the Dirac equation can be solved explicitly for a constant Skyrme configuration and also for a SO(4) symmetric hedgehog configuration. We discuss how the spectrum changes due to the presence of a non-trivial winding number, and also consider more general Skyrme configurations numerically. 31 pages, 6 figures ∗[email protected] 1

Skyrmions in the Fractional Quantum Hall Effect
It is verified that, at small Zeeman energies, the charged excitations in the vicinity of 1/3 filled Landau level are skyrmions of composite fermions, analogous to the skyrmions of electrons near filling factor unity. These are found to be relevant, however, only at very low magnetic fields. PACS numbers: 73.40.Hm Typeset using REVTEX 0Accepted for publication in Solid State Communications (199...
متن کاملSkyrmions in Yang–Mills Theories with Massless Adjoint Quarks
Dynamics of SU(Nc) Yang–Mills theories with Nf adjoint Weyl fermions is quite different from that of SU(Nc) gauge theories with fundamental quarks. The symmetry breaking pattern is SU(Nf ) → SO(Nf ). The corresponding sigma model supports Skyrmions whose microscopic identification is not immediately clear. We address this issue as well as the issue of the Skyrmion stability. The case of Nf = 2 ...
متن کاملHopf invariant for long-wavelength skyrmions in quantum Hall systems for integer and fractional fillings
We show that a Hopf term exists in the effective action of long-wavelength skyrmions in quantum Hall systems for both odd integer and fractional filling factors ν = 1/(2s + 1), where s is an integer. We evaluate the prefactor of the Hopf term using Green function method in the limit of strong external magnetic field using model of local interaction. The prefactor (N) of the Hopf term is found t...
متن کاملS 3 Skyrmions and the Rational Map Ansatz
This paper discusses multi-skyrmions on the 3-sphere S 3 with variable radius L using the rational map ansatz. For baryon number B = 3,. .. , 9 this ansatz produces the lowest energy solutions known so far. By considering the geometry of the model we find an approximate analytic formula for the shape function. This provides an insight why skyrmions have a shell-like structure.
متن کاملSpin, Statistics and Charge of Solitons in (2+1)-Dimensional Theories
Abstract. General topologically invariant microscopical expressions for quantum numbers of particlelike solitons (“skyrmions”) are derived for a class of (2+1)D models. Skyrmions are either half-integer spin fermions with odd electric charge or integer spin bosons with even charge. So they cannot be Anderson’s spinons or holons. General results are exemplified by a square lattice model reminisc...
