Seiberg--Witten maps for gauge invariance and deformations of gravity
S. Marculescu, F. Ruiz Ruiz
A family of diffeomorphism-invariant Seiberg--Witten deformations of gravity is constructed. In a first step Seiberg--Witten maps for an SO(1,3) gauge symmetry are obtained for con…
Noncommutative Einstein-Maxwell pp-waves
S. Marculescu, F. Ruiz Ruiz
The field equations coupling a Seiberg-Witten electromagnetic field to noncommutative gravity, as described by a formal power series in the noncommutativity parameters , is…
Non-Commutative Extensions of the Standard Model
Sorin Marculescu
Four different extensions of the Standard Model to non-commutative space-time are considered. They all have the structure group U_Y(1) x SU_L(2) x SU_c(3) but differ through the wa…
The short-time critical behaviour of the Ginzburg-Landau model with long-range interaction
Y. Chen, S. H. Guo, Z. B. Li +2
The renormalisation group approach is applied to the study of the short-time critical behaviour of the -dimensional Ginzburg-Landau model with long-range interaction of the form…
Drived diffusion of vector fields
S. Marculescu, F. Ruiz Ruiz
A model for the diffusion of vector fields driven by external forces is proposed. Using the renormalization group and the -expansion, the dynamical critical properties of the mo…
Topological Yang-Mills Theory with Two Fermionic Charges. A Superfield Approach on Kähler Manifolds
H. D. Dahmen, S. Marculescu, T. Portmann
The four-dimensional topological Yang-Mills theory with two anticommuting charges is naturally formulated on Kähler manifolds. By using a superspace approach we clarify the structu…
