Abstract

An increase in the size of coherent domains in the one component Φ4 field theory under the influence of a uniformly changing external magnetic field near the critical end point TΦ=Tc,hΦ=0 was proposed recently as an estimate also for the variation of the chiral correlation length of QCD near its respective hypothetical end point in the TQCDQCD plane. The present detailed numerical investigation of the effective model suggests that passing by the critical QCD end point with a realistic rate of temperature change will trigger large amplitude oscillations in the temporal variation of the chiral correlation length. A simple mechanism for producing this phenomenon is suggested.
