Electromagnetic Waves in a Model with Chern-Simons Potential
D. Yu. Pis'mak, Yu. M. Pis'mak, F. J. Wegner
We investigate the appearance of Chern-Simons terms in electrodynamics at the surface/interface of materials. The requirement of locality, gauge invariance and renormalizability in…
Light-cone Hamiltonian flow for positronium
Elena L. Gubankova, Hans-Christian Pauli, Franz J. Wegner +1
The technique of Hamiltonian flow equations is applied to the canonical Hamiltonian of quantum electrodynamics in the front form and 3+1 dimensions. The aim is to generate a bound…
GEOMETRICAL STRING and DUAL SPIN SYSTEMS
G. K. Savvidy, K. G. Savvidy, F. J. Wegner
We are able to perform the duality transformation of the spin system which was found before as a lattice realization of the string with linear action. In four and higher dimensions…
The structure of the spectrum of anomalous dimensions in the N-vector model in 4-epsilon dimensions
Stefan K. Kehrein, Franz Wegner
In a recent publication we have investigated the spectrum of anomalous dimensions for arbitrary composite operators in the critical N-vector model in 4-epsilon dimensions. We could…
Geometrical String and Spin Systems
G. K. Savvidy, F. J. Wegner
We formulate a new geometrical string on the euclidean lattice. It is possible to find such spin systems with local interaction which reproduce the same surface dynamics.In the thr…
