Scrutinizing the pion condensed phase
Stefano Carignano, Luca Lepori, Andrea Mammarella +2
When the isospin chemical potential exceeds the pion mass, charged pions condense in the zero-momentum state forming a superfluid. Chiral perturbation theory provides a very powerf…
Consistent parameter fixing in the quark-meson model with vacuum fluctuations
Stefano Carignano, Michael Buballa, Wael Elkamhawy
We revisit the renormalization prescription for the quark-meson model in an extended mean-field approximation, where vacuum quark fluctuations are included. At a given cutoff scale…
Inhomogeneous chiral condensates
Michael Buballa, Stefano Carignano
The chiral condensate, which is constant in vacuum, may become spatially modulated at moderately high densities where in the traditional picture of the QCD phase diagram a first-or…
Inhomogeneous phases in the quark-meson model with vacuum fluctuations
Stefano Carignano, Michael Buballa, Bernd-Jochen Schaefer
Inhomogeneous chiral-symmetry breaking phases at non-vanishing chemical potential and temperature are studied within a two-flavor quark-meson model in the chiral limit. The analysi…
