Quantum Field Theory on Noncommutative Space-Times and the Persistence of Ultraviolet Divergences
M. Chaichian, A. Demichev, P. Presnajder
We study properties of a scalar quantum field theory on two-dimensional noncommutative space-times. Contrary to the common belief that noncommutativity of space-time would be a key…
Faddeev-Hopf knots: Dynamics of linked un-knots
Jarmo Hietarinta, Petri Salo
We have studied numerically Faddeev-Hopf knots, which are defined as those unit-vector fields in that have a nontrivial Hopf charge and minimize Faddeev's Lagrangian. A given…
Infrared Behaviour of Softly Broken SQCD and Its Dual
Andreas Karch, Tatsuo Kobayashi, Jisuke Kubo +1
Applying the recently obtained results on the renormalization of soft supersymmetry-breaking parameters, we investigate the infrared behaviour of the softly broken supersymmetric Q…
Vacuum Structure of Softly Broken N=1 Supersymmetric QCD
Masud Chaichian, Tatsuo Kobayashi
We study softly broken N=1 supersymmetric QCD with the gauge group and flavors of quark pairs. We investigate vacuum structure of the theory with generic soft super…
Partially Dual variables in SU(2) Yang-Mills Theory
Ludvig Faddeev, Antti J. Niemi
We propose a reformulation of SU(2) Yang-Mills theory in terms of new variables. These variables are appropriate for describing the theory in its infrared limit, and indicate that…
(Meta)stable closed vortices in 3+1 dimensional gauge theories with an extended Higgs sector
Antti J. Niemi, Kaupo Palo, Sami Virtanen
In gauge theories with an extended Higgs sector the classical equations of motion can have solutions that describe stable, closed finite energy vortices. Such vortices separate two…
