Towards the phase diagram of cold and dense heavy QCD
Amine Chabane, Owe Philipsen
The thermodynamics of QCD with sufficiently heavy dynamical quarks can be described by a three-dimensional Polyakov loop effective theory, obtained after a truncated character and…

The light Roberge-Weiss tricritical endpoint at imaginary isospin and baryon chemical potential
Bastian B. Brandt, Amine Chabane, Volodymyr Chelnokov +3
Imaginary chemical potentials serve as a useful tool to constrain the QCD phase diagram and to gain insight into the thermodynamics of strongly interacting matter. In this study, w…

Roberge-Weiss transitions at imaginary isospin chemical potential
Amine Chabane, Gergely Endrödi
At finite imaginary values of the chemical potential, QCD is free of the sign problem. Moreover, at high temperatures the partition function exhibits a new symmetry (the Roberge-We…
