Magnetic knots of deconfined CP-odd matter in heavy-ion collisions

Maxim Chernodub 1, 2

(25/01/2011)

We point out that metastable knots of deconfined hot quark matter may exist in the quark-gluon plasma due to local parity violating effects. These knots are stabilized by strong magnetic fields which induce electric currents via the chiral magnetic effect. The magnetic field in the knot resembles the spheromak plasma state which appears in the nuclear fusion devices. The size of the knot is inversely proportional to the chiral conductivity of the plasma, and the parity and charge-parity symmetries are broken inside the knot. We argue that these knots may be created in noncentral heavy-ion collisions.
