QCD axions and domain walls in dense matter under compact stellar conditions
Zhen-Yan Lu, Shu-Peng Wang, Qi Lu +2
In compact stellar environments, the stability of dense QCD matter requires the simultaneous fulfillment of charge neutrality and beta equilibrium. In this work, we study how tempe…

Assessing the Reconstruction of the Critical Line in the QCD Phase Diagram from Imaginary to Real Chemical Potential
Fabrizio Murgana, Marco Ruggieri
We test a technique adopted in the lattice simulations framework, to reconstruct the chiral-phase boundary at real chemical potential, , via extrapolation from imaginary .…

Topological Susceptibility in the Superconductive Phases of Quantum Chromodynamics: a Dyson-Schwinger Perspective
Fabrizio Murgana, Giorgio Comitini, Marco Ruggieri
We test non-perturbative gluon propagators recently studied in the literature, by computing the topological susceptibility, , of the superconductive phases of Quantum Chromodyn…
