Critical fluctuations of the quark density in nuclei
We study the static scalar susceptibility of the nuclear medium, i.e., the change of the quark condensate for a small modification of the quark mass.In the linear sigma model it is linked to the in-medium sigma propagator.Near the critical density for the chiral phase transition it becomes large, re...
