Quark mass dependence of a QCD critical point and structure of the Columbia plot
Julian Bernhardt, Christian S. Fischer
We study the quark-mass dependence of the QCD critical point at varying bare up/down quark masses with fixed strange quark mass. We explore the corresponding second-order critical…
New Tool to Detect Inhomogeneous Chiral Symmetry Breaking
Theo F. Motta, Julian Bernhardt, Michael Buballa +1
In this letter, we discuss a novel method to search for inhomogeneous chiral symmetry breaking in theories with fermions. The prime application we have in mind is QCD, but the meth…
Inhomogenuous instabilities at large chemical potential in a rainbow-ladder QCD model
Theo F. Motta, Julian Bernhardt, Michael Buballa +1
In this work we continue our efforts to study the existence of a phase with an inhomogeneous, i.e., spatially varying, chiral condensate in QCD. To this end we employ a previously…
QCD phase transitions in the light quark chiral limit
Julian Bernhardt, Christian S. Fischer
We investigate the order of the QCD chiral transition in the limit of vanishing bare up/down quark masses and variations of the bare strange-quark mass $0 \le m_{\mathrm{s}} \le \i…
Towards a Stability Analysis of Inhomogeneous Phases in QCD
Theo F. Motta, Julian Bernhardt, Michael Buballa +1
The possible occurrence of crystalline or inhomogeneous phases in the QCD phase diagram at large chemical potential has been under investigation for over thirty years. Such phases…
From imaginary to real chemical potential QCD with functional methods
Julian Bernhardt, Christian S. Fischer
We investigate the quality of the extrapolation procedure employed in Ref. [1] to extract the crossover line at real chemical potential from lattice data at imaginary potential. To…
Critical Endpoint of QCD and Baryon Number Fluctuations in a Finite Volume
Julian Bernhardt, Christian S. Fischer, Philipp Isserstedt
We summarize recent results on the volume dependence of the location of the critical endpoint in the QCD phase diagram. To this end, we employ a sophisticated combination of Lattic…
Finite-volume effects in baryon number fluctuations around the QCD critical endpoint
Julian Bernhardt, Christian S. Fischer, Philipp Isserstedt
We present results for the volume dependence of baryon number fluctuations in the vicinity of the (conjectured) critical endpoint of QCD. They are extracted from the nonperturbativ…
Critical endpoint of QCD in a finite volume
Julian Bernhardt, Christian S. Fischer, Philipp Isserstedt +1
We investigate the impact of finite volume and the corresponding restrictions on long-range correlations on the location of the critical endpoint in the QCD phase diagram. To this…
