Origin of the Chemical Elements

- T. Rauscher, A. Patkós
- Physics
- 25 November 2010

This review provides the necessary background from astrophysics, nuclear, and particle physics to understand the cosmic origin of the chemical elements. It reflects the year 2009 state of the art in… Expand

Screened Perturbation Theory

- F. Karsch, A. Patkós, P. Petreczky
- Physics
- 20 February 1997

A new perturbative scheme is proposed for the evaluation of the free energy density of field theories at finite temperature. The screened loop expansion takes into account exactly the phenomenon of… Expand

Conformal structure in the spectrum of an altered quantum Ising chain

The Ising model with an infinite line of defects is mapped onto a strip with two defect lines. The Hamiltonian spectrum is studied at the bulk critical point. Its exact diagonal form is found for an… Expand

Analytic results for the effective theory of thermal Polyakov loops

- P. Damgaard, A. Patkós
- Physics
- 22 May 1986

Abstract Analytic results for deconfinement in the effective theory of Polyakov loops are presented: (i) in the neighborhood of the lower critical dimensionality ( D = 1); (ii) at infinite number of… Expand

The Ising quantum chain with defects (I). The exact solution

- M. Henkel, A. Patkós, M. Schlottmann
- Physics
- 6 March 1989

The Ising quantum chain with n arbitrarily placed defects is solved exactly. At the bulk critical point, the model is conformally invariant if and only if the defects form a commensurate structure.… Expand

High energy neutrinos and photons from curvature pions in magnetars

- T. Herpay, S. Razzaque, A. Patkós, P. Mészáros
- Physics
- 30 July 2008

We discuss the relevance of the curvature radiation of pions in strongly magnetized pulsars or magnetars, and their implications for the production of TeV energy neutrinos detectable by cubic… Expand

Continuous kink condensation in the planar quantum hamiltonian

Abstract The critical behaviour of the 1 d quantum planar hamiltonian is investigated using a mean disorder-field variational method. We show that localised kinks are gradually condensating as a… Expand

Effective dielectric theory from QCD

- H. Nielsen, A. Patkós
- Physics
- 8 February 1982

Abstract New effective fields are defined in QCD by averaging the phase factor P exp∫ x 0 x 0 + ϵ iA μ d x μ in small four-dimensional boxes. Their effective lagrangian is constructed explicitly for… Expand

Series expansion solution of the Wegner-Houghton renormalisation group equation

- A. Margaritis, G. Ódor, A. Patkós
- Physics
- 1 March 1988

The momentum independent projection of the Wegner-Houghton renormalisation group equation is solved with power series expansion. Convergence rate is analyzed for then-vector model. Further evidence… Expand

Non-Gaussian fixed points in fermionic field theories without auxiliary Bose fields

- A. Jakovác, A. Patkós, P. P'osfay
- Physics
- 12 June 2014

The functional equation governing the renormalization flow of fermionic field theories is investigated in $$d$$d dimensions without introducing auxiliary Bose fields on the example of the Gross–Neveu… Expand
