The QCD equation of state with dynamical quarks

- S. Borsányi, G. Endrodi, +5 authors K. Szabó
- Physics
- 15 July 2010

The present paper concludes our investigation on the QCD equation of state with 2 + 1 staggered flavors and one-link stout improvement. We extend our previous study [JHEP01 (2006) 089] by choosing… Expand

- Physical review letters
- 21 May 2004

We show that the well-known linear Langevin equation, modeling the Brownian motion and leading to a Gaussian stationary distribution of the corresponding Fokker-Planck equation, is changed by the… Expand

Quarkonium correlators and spectral functions at zero and finite temperature

- A. Jakovác, P. Petreczky, K. Petrov, A. Velytsky
- Physics
- 13 November 2006

We study quarkonium correlators and spectral functions at zero and finite temperature using the anisotropic Fermilab lattice formulation with anisotropy {xi}=2 and 4. To control cut-off effects we… Expand

Representation of spectral functions and thermodynamics

- A. Jakovác
- Physics
- 5 June 2012

In this paper we study the question of effective field assignment to measured or nonperturbatively calculated spectral functions. The straightforward procedure is to approximate it by a sum of… Expand

Classical statistical mechanics and Landau damping

- W. Buchmuller, A. Jakovác
- Physics
- 28 May 1997

Abstract We study the retarded response function in scalar φ4-theory at finite temperature. We find that in the high-temperature limit the imaginary part of the self-energy is given by the classical… 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

Fluctuation, Dissipation, and Non-Boltzmann Energy Distributions

- T. Biró, A. Jakovác
- Physics
- 2019

After reviewing the field theoretical description of the conventional thermal equilibrium and studying the linear relaxation to this equilibrium, it is interesting to consider problems arising in… Expand

Interacting two-particle states in the symmetric phase of the chiral Nambu--Jona-Lasinio model

- A. Jakovác, A. Patkós
- Physics
- 18 February 2019

The renormalisation group flow of the chiral Nambu--Jona-Lasinio (NJL) model with one fermion flavor is mapped out in the symmetric phase with the help of the Functional Renormalisation Group (FRG)… Expand

Role of surface anisotropy for magnetic impurities in electron dephasing and energy relaxation and their size effect.

- O. Ujs'aghy, A. Jakovác, A. Zawadowski
- Materials Science, Medicine
- Physical review letters
- 11 June 2004

Recently the electron dephasing and energy relaxation due to different magnetic impurities have been extensively investigated experimentally in thin wires, and in this Letter these quantities are… Expand

Local potential approximation for the renormalization group flow of fermionic field theories

- A. Jakovác, A. Patkós
- Physics
- 11 June 2013

The second functional derivative of the effective potential of pure fermionic field theories is rewritten in a factorized form which facilitates the evaluation of the renormalisation flow rate of the… Expand
