QCD topology with electromagnetic fields and the axion-photon coupling
Bastian Brandt, Francesca Cuteri, Gergely Endrődi +2
The introduction of non-orthogonal electric and magnetic fields in the QCD vacuum enhances the weight of topological sectors with a nonzero topological charge. For weak fields, the…
Anomalous transport phenomena on the lattice
Bastian B. Brandt, Francesca Cuteri, Gergely Endrődi +2
The interrelation between quantum anomalies and electromagnetic fields leads to a series of non-dissipative transport effects in QCD. In this work we study anomalous transport phen…
Role of inhomogeneities in the flattening of the quantum effective potential
Gergely Endrődi, Tamás G. Kovács, Gergely Markó
We investigate the role of inhomogeneous field configurations in systems with a spontaneously broken continuous global symmetry. Spontaneous breaking is usually defined as a specif…
Apparent convergence of Padé approximants for the crossover line in finite density QCD
Attila Pásztor, Zsolt Szép, Gergely Markó
We propose a novel Bayesian method to analytically continue observables to real baryochemical potential in finite density QCD. Taylor coefficients at and data at imag…
The model as an effective light meson theory: A lattice-continuum comparison
Gergely Markó, Zsolt Szép
We investigate the possibility of using the 4 dimensional symmetric model as an effective theory for the sigma-pion system. We carry out lattice Monte Carlo simulation…
Padé approximants and analytic continuation of Euclidean Phi-derivable approximations
Gergely Markó, Urko Reinosa, Zsolt Szép
We investigate the Padé approximation method for the analytic continuation of numerical data and its ability to access, from the Euclidean propagator, both the spectral function an…
Loss of solution in the symmetry improved Phi-derivable expansion scheme
Gergely Markó, Urko Reinosa, Zsolt Szép
We consider the two-loop Phi-derivable approximation for the O(2)-symmetric scalar model, augmented by the symmetry improvement introduced in [A. Pilaftsis and D. Teresi, Nucl. Phy…
The O(N)-model within the Phi-derivable expansion to order lambda^2: on the existence, UV and IR sensitivity of the solutions to self-consistent equations
Gergely Markó, Urko Reinosa, Zsolt Szép
We discuss various aspects of the O(N)-model in the vacuum and at finite temperature within the Phi-derivable expansion scheme to order lambda^2. In continuation to an earlier work…
Bose-Einstein condensation and Silver Blaze property from the two-loop -derivable approximation
Gergely Markó, Urko Reinosa, Zsolt Szép
We extend our previous investigation of the two-loop -derivable approximation to finite chemical potential and discuss Bose-Einstein condensation (BEC) in the case of a char…
Thermodynamics and phase transition of the O(N) model from the two-loop Phi-derivable approximation
Gergely Markó, Urko Reinosa, Zsolt Szép
We discuss the thermodynamics of the O(N) model across the corresponding phase transition using the two-loop Phi-derivable approximation of the effective potential and compare our…
Broken phase effective potential in the two-loop Phi-derivable approximation and nature of the phase transition in a scalar theory
Gergely Markó, Urko Reinosa, Zsolt Szép
We study the phase transition of a real scalar phi^4 theory in the two-loop Phi-derivable approximation using the imaginary time formalism, extending our previous (analytical) disc…
Influence of the Polyakov loop on the chiral phase transition in the two flavor chiral quark model
G. Marko, Zs. Szep
The SU(2)_L x SU(2)_R chiral quark model consisting of the (sigma,pi) meson multiplet and the constituent quarks propagating on the homogeneous background of a temporal gauge field…
