The Chiral Magnetic Effect
Kenji Fukushima, Dmitri E. Kharzeev, Harmen J. Warringa
Topological charge changing transitions can induce chirality in the quark-gluon plasma by the axial anomaly. We study the equilibrium response of the quark-gluon plasma in such a s…
Implications of CP-violating transitions in hot quark matter on heavy ion collisions
Harmen J. Warringa
Quantum Chromodynamics (QCD) predicts that topological charge changing transitions will take place in hot quark matter. Such transitions induce P- and CP-violating effects. We will…
Color superconducting matter in a magnetic field
Kenji Fukushima, Harmen J. Warringa
We investigate the effect of a magnetic field on cold dense three-flavor quark matter using an effective model with four-Fermi interactions with electric and color neutrality taken…
Heating the O(N) nonlinear sigma model
Harmen J. Warringa
The thermodynamics of the O(N) nonlinear sigma model in 1+1 dimensions is studied. We calculate the finite temperature effective potential in leading order in the 1/N expansion and…
