We imagine shining light on a lump of cold dense quark matter, in the CFL phase and therefore a transparent insulator. We calculate the angles of reflection and refraction, and the intensity of the reflected and refracted light. Although the only potentially observable context for this phenomenon (reflection of light from and refraction of light through an illuminated quark star) is unlikely to...

We study the effect of SU (3) flavor breaking on high density quark matter. We discuss, in particular, the effect a non-zero electron chemical potential and a finite strange quark mass. We argue that these perturbations trigger pion or kaon condensation. The critical chemical potential behaves as µ e ∼ √ mm s ∆/p F and the critical strange quark mass as m s ∼ m 1/3 ∆ 2/3 , where m is the light ...

The nonlinear mean-eld model of nuclear matter II

The relativistic impulse optical model of nuclei is investigated using derivative coupling potential. We have found the suppression of the negative-energy propagation compared to the usual t potential. However it can be taken into account by the renormalized potential in the Dirac equation. Thus the Dirac phenomenology is still valid. Recent extensive developments of relativistic nuclear models...
