Hall effects in Carroll dynamics
L. Marsot, P. -M. Zhang, M. Chernodub +1
``Do Carroll particles move?'' The answer depends on the characteristics of the particle such as its mass, spin, electric charge, and magnetic moment. A massive Carroll particle (c…
Axially-symmetric stationary solutions in a pure SU(3) QCD
D. G. Pak, P. M. Zhang
We propose an ansatz for a class of regular axially-symmetric solutions in SU(3) QCD. After averaging over time period the solution can be treated as a non-topological monopole-ant…
Perturbative width of open rigid strings
A. S. Bakry, M. A. Deliyergiyev, A. Galal +1
We present perturbative calculation of the width of the energy profile of rigid strings up to two loops in D dimensions. The perturbative expansion of the extrinsic curvature term…
Duality and helicity: the photon wave function approach
M. Elbistan, P. A. Horvathy, P. -M. Zhang
The photon wave equation proposed in terms of the Riemann-Silberstein vector is derived from a first-order Dirac/Weyl-type action principle. It is symmetric w.r.t. duality transfor…
Gauge invariant gluon spin operator for spinless non-linear wave solutions
Bum-Hoon Lee, Youngman Kim, D. G. Pak +2
We consider non-linear wave type solutions with mass scale parameter and vahished canonical spin density operator in a pure SU(2) quantum chtomodynamics (QCD). A new stationary sol…
Helicity of spin-extended chiral particles
M. Elbistan, C. Duval, P. A. Horvathy +1
The helicity of a free massless relativistic particle, , is generalized, for a particle in an electromagnetic field, to ,…
Wigner-Souriau translations and Lorentz symmetry of chiral fermions
C. Duval, M. Elbistan, P. A. Horvathy +1
Chiral fermions can be embedded into Souriau's massless spinning particle model by "enslaving" the spin, viewed as a gauge constraint. The latter is not invariant under Lorentz boo…
Monopoles without magnetic charges: Finite energy monopole-antimonopole configurations in CP1 model and restricted QCD
L. P. Zou, P. M. Zhang, D. G. Pak
We propose a new type of regular monopole-like field configuration in quantum chromodynamics (QCD) and CP^1 model. The monopole configuration can be treated as a monopole-antimonop…
Knot topology in QCD
L. P. Zou, P. M. Zhang, D. G. Pak
We consider topological structure of classical vacuum solutions in quantum chromodynamics. Topologically non-equivalent vacuum configurations are classified by non-trivial second a…
Newton-Hooke type symmetry of anisotropic oscillators
P. M. Zhang, P. A. Horvathy, K. Andrzejewski +2
The rotation-less Newton--Hooke - type symmetry found recently in the Hill problem and instrumental for explaining the center-of-mass decomposition is generalized to an arbitrary a…
Non-commutative oscillator with Kepler-type dynamical symmetry
P. M. Zhang, P. A. Horvathy, J. -P. Ngome
A 3-dimensional non-commutative oscillator with no mass term but with a certain momentum-dependent potential admits a conserved Runge-Lenz vector, derived from the dual description…
