Demonstration of non-Fermi-liquid effects due to dynamical gluon screening
Quantitative evaluation of spin susceptibility in quark matter
Abstract
Magnetic properties of quark matter is discussed by evaluating the spin susceptibility within Fermi-liquid theory. We take into account the dynamical and static screening effects. At finite temperature, an anomalous T^2 ln T term for susceptibity is shown as a non-Fermi-liquid effect due to the dynamical screening of transverse gluons.
