] | With a modified chemical potential dependent effective model for the gluon propagator, we try to locate the critical end point (CEP) of strongly interacting matter in the framework of Dyson-Schwinger equations (DSE). Beyond the chiral limit, we find that Nambu solution and Wigner solution could coexist in some area. Us... |

of external magnetic fields, highlighting the role of spin. We show, contrary
to long-held belief, that the $n$-${\bar n}$ transition rate need not be
suppressed, opening new opportunities for its empirical study.
