QFT on flat, compact, orientable manifolds
Sebestyen Nagy, Daniel Nogradi
Motivated by the recent observation that rotating space-times at finite temperature can be described by particular flat, compact, orientable manifolds, which are different from $\m…
Dilaton in scalar QFT: a no-go theorem in and dimensions
Daniel Nogradi, Balint Ozsvath
Spontaneous scale invariance breaking and the associated Goldstone boson, the dilaton, is investigated in renormalizable, unitary, interacting non-supersymmetric scalar field theor…
Vector fields, RG flows and emergent gauge symmetry
Daniel Nogradi
We consider the most general perturbatively renormalizable theory of vector fields in four dimensions with a global SU(N) symmetry and massless couplings. The Lagrangian contains 1…
On the charge density and asymptotic tail of a monopole
Derek Harland, Daniel Nogradi
We propose a new definition for the abelian magnetic charge density of a non-abelian monopole, based on zero-modes of an associated Dirac operator. Unlike the standard definition o…
Shear viscosity of pure Yang-Mills theory at strong coupling
Antal Jakovac, Daniel Nogradi
We calculate the shear viscosity to entropy density ratio in pure SU(N) Yang-Mills theory below the critical temperature using the strong coupling expansion. The result for the eta…
Multi-calorons and their moduli
Daniel Nogradi
Pure Yang-Mills instantons are considered on S^1 x R^3 -- so-called calorons. The holonomy -- or Polyakov loop around the thermal S^1 at spatial infinity -- is assumed to be a non-…
