Property of the low-lying states at the critical point of the phase transition in U(4) vibron model
Ze-bo Li, Xia-ping Tang, Yu Zhang +3
We study the properties of the low-lying states at the critical point of the phase transition from U(3) to O(4) symmetry in the U(4) vibron model in detail. By analyzing the genera…
Chemical potential and the gap equation
Huan Chen, Wei Yuan, Lei Chang +3
In general the kernel of QCD's gap equation possesses a domain of analyticity upon which the equation's solution at nonzero chemical potential is simply obtained from the in-vacuum…
Rotation-driven prolate-to-oblate shape phase transition in 190W: A projected shell model study
Yang Sun, Philip M. Walker, Fu-Rong Xu +1
A shape phase transition is demonstrated to occur in 190W by applying the Projected Shell Model, which goes beyond the usual mean-field approximation. Rotation alignment of neutron…
Flavour symmetry breaking and meson masses
Mandar S. Bhagwat, Lei Chang, Yu-Xin Liu +2
The axial-vector Ward-Takahashi identity is used to derive mass formulae for neutral pseudoscalar mesons. Flavour symmetry breaking entails non-ideal flavour content for these stat…
Collective Shape-Phases of Interacting Fermion Systems
Yu-xin Liu, Zhan-feng Hou, Yu Zhang +1
A microscopic theory is presented for identifying shape-phase structures and transitions in interacting fermion systems. The method provides a microscopic description for collectiv…
Dynamical chiral symmetry breaking and a critical mass
Lei Chang, Yu-Xin Liu, Mandar S. Bhagwat +2
On a bounded, measurable domain of non-negative current-quark mass, realistic models of QCD's gap equation can simultaneously admit two inequivalent dynamical chiral symmetry break…
