Landau gauge Yang-Mills correlation functions
Anton K. Cyrol, Leonard Fister, Mario Mitter +2
We investigate Landau gauge Yang-Mills theory in a systematic vertex expansion scheme for the effective action with the functional renormalisation group. Particular focus i…
Functional renormalisation group in a finite volume
Leonard Fister, Jan Martin Pawlowski
We study a -theory at finite temperature in a finite volume. Quantum, thermal and volume fluctuations are treated with the functional renormalisation group. Specifically, we f…
From Quarks and Gluons to Hadrons: Chiral Symmetry Breaking in Dynamical QCD
Jens Braun, Leonard Fister, Jan M. Pawlowski +1
We present an analysis of the dynamics of two-flavour QCD in the vacuum. Special attention is payed to the transition from the high energy quark-gluon regime to the low energy regi…
Angular distribution of medium-induced QCD cascades
Jean-Paul Blaizot, Leonard Fister, Yacine Mehtar-Tani
We provide a complete description of the angular distribution of gluons in a medium-induced QCD cascade. We identify two components in the distribution, a soft component dominated…
Medium-induced jet evolution: wave turbulence and energy loss
Leonard Fister, Edmond Iancu
We study the gluon cascade generated via successive medium-induced branchings by an energetic parton propagating through a dense QCD medium. We focus on the high-energy regime wher…
Exploratory study of the temperature dependence of magnetic vertices in SU(2) Landau gauge Yang--Mills theory
Leonard Fister, Axel Maas
Vertices describe the interactions between the fundamental degrees of freedom, and are therefore of vital importance in many ab-initio descriptions of field theory, especially usin…
Phase transitions in dense 2-colour QCD
Tamer Boz, Seamus Cotter, Leonard Fister +1
We investigate 2-colour QCD with 2 flavours of Wilson fermion at nonzero temperature T and quark chemical potential mu, with a pion mass of 700 MeV (m_pi/m_rho=0.8). From temperatu…
Gluon spectral functions and transport coefficients in Yang--Mills theory
Michael Haas, Leonard Fister, Jan M. Pawlowski
We compute non-perturbative gluon spectral functions at finite temperature in quenched QCD with the maximum entropy method. We also provide a closed loop equation for the spectral…
Critical Point and Deconfinement from Dyson-Schwinger Equations
Jan Luecker, Christian S. Fischer, Leonard Fister +1
We employ the Dyson-Schwinger equations for quark and gluon propagators in order to study QCD with 2+1 flavours at finite temperature and density. In a suitable truncation for thes…
Polyakov loop potential at finite density
Christian S. Fischer, Leonard Fister, Jan Luecker +1
The Polyakov loop potential serves to distinguish between the confined hadronic and the deconfined quark-gluon plasma phases of QCD. For Nf=2+1 quark flavors with physical masses w…
Phase transitions and gluodynamics in 2-colour matter at high density
Tamer Boz, Seamus Cotter, Leonard Fister +2
We investigate 2-colour QCD with 2 flavours of Wilson fermion at nonzero temperature T and quark chemical potential mu, with a pion mass of 700 MeV (m_pi/m_rho=0.8). From temperatu…
Quark Confinement from Correlation Functions
Leonard Fister, Jan M. Pawlowski
We study quark confinement by computing the Polyakov loop potential in Yang--Mills theory within different non-perturbative functional continuum approaches [1]. We extend previous…
Confinement from Correlation Functions
Leonard Fister, Jan M. Pawlowski
We compute the Polyakov loop potential in Yang--Mills theory from the fully dressed primitively divergent correlation functions only. This is done in a variety of functional approa…
Yang-Mills correlation functions at finite temperature
Leonard Fister, Jan M. Pawlowski
We put forward a continuum approach for computing finite temperature correlation functions in Yang-Mills theory. This is done in a functional renormalisation group setting which al…
Yang-Mills theory at non-vanishing temperature
Leonard Fister, Jan M. Pawlowski
We compute ghost and gluon propagators of Yang-Mills theory in the Landau gauge at non-vanishing temperature within a functional renormalisation group setting. We construct purely…
On the Infrared Behaviour of Landau Gauge Yang-Mills Theory with Differently Charged Scalar Fields
Reinhard Alkofer, Leonard Fister, Axel Maas +1
Recently it has been argued that infrared singularities of the quark-gluon vertex of Landau gauge QCD can confine static quarks via a linear potential. It is demonstrated that the…
On the Infrared Behavior of Landau Gauge Yang-Mills Theory with a Fundamentally Charged Scalar Field
Leonard Fister, Reinhard Alkofer, Kai Schwenzer
Recently it has been shown that infrared singularities of Landau gauge QCD can confine static quarks via a linearly rising potential. We show that the same mechanism can also provi…
Infrared Behaviour of Landau Gauge Yang-Mills Theory with a Fundamentally Charged Scalar Field
Leonard Fister
The infrared behaviour of the n-point functions of a Yang-Mills theory with a charged scalar field in the fundamental representation of SU(N) is studied in the formalism of Dyson-S…
