Conformal Mapping, Power Corrections, and the QCD Bound State Spectrum
H. F. Jones, A. Ritz, I. L. Solovtsov
We analyze the heavy quark bound state spectrum using an order-dependent conformal mapping to re-sum the perturbative expansion for current correlators. The procedure consists of t…
On the Phase Structure of the 3D SU(2)--Higgs Model and the Electroweak Phase Transition
T. S. Evans, H. F. Jones, A. Ritz
The phase structure of the 3D SU(2)--Higgs model, the dimensionally reduced effective theory for the electroweak model at finite temperature, is analysed on the lattice using a var…
On The Beta-Function in N=2 Supersymmetric Yang-Mills Theory
A. Ritz
The constraints of N=2 supersymmetry, in combination with several other quite general assumptions, have recently been used to show that N=2 supersymmetric Yang-Mills theory has a l…
On the Symmetry of Real-Space Renormalisation
D. C. Brody, A. Ritz
A natural geometry, arising from the embedding into a Hilbert space of the parametrised probability measure for a given lattice model, is used to study the symmetry properties of r…
Restoration of Isotropy for Spin Models
D. C. Brody, A. Ritz
Using real-space renormalisation techniques we analyse the Ising model on a Sierpiński gasket with anisotropic microscopic couplings, and observe a restoration of isotropy on macro…
