On Nonexistence of Magnetic Charge in Pure Yang-Mills Theories
A. Kovner, M. Lavelle, D. McMullan
We prove that magnetic charge does not exist as a physical observable on the physical Hilbert space of the pure SU(2) gauge theory. The abelian magnetic monopoles seen in lattice s…
Magnetic Z(N) symmetry in 2+1 dimensions
Alex Kovner
This review describes the role of magnetic symmetry in 2+1 dimensional gauge theories. In confining theories without matter fields in fundamental representation the magnetic symmet…
Fundamental Matter and the Deconfining Phase Transition in 2+1 D
Gerald V. Dunne, Alex Kovner, Shinsuke M. Nishigaki
We analyze the effect of heavy fundamentally charged particles on the finite temperature deconfining phase transition in the 2+1 dimensional Georgi-Glashow model. We show that in t…
Taming the BFKL Intercept via Gluon Saturation
Alexander Kovner, Urs Achim Wiedemann
We show that the inclusion of parton density effects in the perturbative small-x evolution reduces the strength of the powerlike growth of total hadronic cross sections.
Variational analysis of the deconfinement phase transition
I. I. Kogan, A. Kovner, J. G. Milhano
We study the deconfining phase transition in 3+1 dimensional pure SU(N) Yang-Mills theory using a gauge invariant variational calculation. We generalize the variational ansatz of P…
Field-dependent surface impedance tensor in amorphous wires with two types of magnetic anisotropy: helical and circumferential
D. P. Makhnovskiy, L. V. Panina, D. J. Mapps
This paper concerns the theoretical and experimental investigation of the magneto-impedance (MI) effect in amorphous wires in terms of the surface impedance tensor. Physical concep…
Effect of transition layers on the electromagnetic properties of composites containing conducting fibres
D. P. Makhnovskiy, L. V. Panina, D. J. Mapps +1
The approach to calculating the effective dielectric and magnetic response in bounded composite materials is developed. The method is essentially based on the renormalisation of th…
Field dependent permittivity of composite materials containing ferromagnetic wires
D. P. Makhnovskiy, L. V. Panina
The effective permittivity of composites containing ferromagnetic microwires has been analysed within a one-particle approximation, by considering a wire piece as an independent sc…
No Froissart Bound from Gluon Saturation
Alexander Kovner, Urs Achim Wiedemann
In the previous work hep-ph/0112140, hep-ph/0204277, we showed that while the nonlinear QCD evolution equation of Balitsky and Kovchegov (BK) leads to saturation of the scattering…
Monopoles, Vortices and Strings: Confinement and Deconfinement in 2+1 Dimensions at Weak Coupling
Ian I. Kogan, Alex Kovner
We consider, from several complementary perspectives, the physics of confinement and deconfinement in the 2+1 dimensional Georgi-Glashow model. Polyakov's monopole plasma and 't Ho…
Optomagnetic composite medium with conducting nanoelements
L. V. Panina, A. N. Grigorenko, D. P. Makhnovskiy
A new type of metal-dielectric composites has been proposed that is characterised by a resonance-like behaviour of the effective permeability in the infrared and visible spectral r…
Perturbative Saturation and the Soft Pomeron
Alex Kovner, Urs Achim Wiedemann
We show that perturbation theory provides two distinct mechanisms for the power like growth of hadronic cross sections at high energy. One, the leading BFKL effect is due to the gr…
