Complex BPS Skyrmions with real energy
نویسندگان
چکیده
We propose and investigate several complex versions of extensions restrictions the Skyrme model with a well-defined Bogomolny-Prasad-Sommerfield (BPS) limit. The models studied possess kink, anti-kink, semi-kink, massless purely imaginary compacton BPS solutions that all have real energies. reality energies for particular solution is guaranteed when modified antilinear CPT-symmetry maps Hamiltonian functional to its parity time-reversed conjugate field itself or new degenerate energy. In addition known Skyrmion configurations we find types refer as step, cusp, shell, solutions.

Susy Quantum Mechanics with Complex Superpotentials and Real Energy Spectra
We extend the standard intertwining relations used in Supersymmetrical (SUSY) Quantum Mechanics which involve real superpotentials to complex superpotentials. This allows to deal with a large class of non-hermitean Hamiltonians and to study in general the isospectrality between complex potentials. In very specific cases we can construct in a natural way ”quasicomplex” potentials which we define...
متن کاملSkyrmions with massive pions
In the Skyrme model with massless pions, the minimal energy multi-Skyrmions are shell-like, with the baryon density localized on the edges of a polyhedron that is approximately spherical and generically of the fullerene-type. In this paper we show that in the Skyrme model with massive pions these configurations are unstable for sufficiently large baryon number. Using numerical simulations of th...
متن کاملMulti-Skyrmions with Vector Mesons
It is known that including vector mesons stabilizes the size of a Skyrmion without the need for a Skyrme term. This paper provides the first results for static multiSkyrmions in such a theory. The rational map ansatz is used to investigate multiSkyrmions in a theory which includes the ω vector meson and has no Skyrme term. Bound states with baryon numbers two, three and four are found, which ha...
متن کاملLight Nuclei as Quantized Skyrmions: Energy Spectra and Form Factors
We review the SU(2) Skyrme model and describe its topological soliton solutions, which are called Skyrmions. Skyrmions provide a model of nuclei in which the conserved topological charge is identified with the baryon number of a nucleus. The semiclassical quantum theory of Skyrmions, in which they are treated as rigid bodies spinning in space and isospace, is described. We derive the energy spe...
متن کاملLow-Energy Limit of Yang–Mills with Massless Adjoint Quarks: Chiral Lagrangian and Skyrmions
If the fundamental quarks of QCD are replaced by massless adjoint quarks the pattern of the chiral symmetry breaking drastically changes compared to the standard one. It becomes SU(Nf ) →SO(Nf ). While for Nf = 2 the chiral Lagrangian describing the “pion” dynamics is well-known, this is not the case at Nf > 2. We outline a general strategy for deriving chiral Lagrangians for the coset spaces M...
