Abstract |
|
|
| We look at two well known examples of interacting systems relating to condensed
matter in which we put the strong interacting parameters. At high quark chemical
potentials and low temperatures we study the entropy arising from the excitation in the
BCS model of superconductivity and the Bose-Einstein condensation (BEC) of colored
quark pairs. We compare it with the ground state entropy for a system consisting of
two colored quarks. In the BCS model we found that the entropy strongly depends
on the energy gap. Both for the very small values of the momenta as well as those
much greater than the characterizing Fermi momentum pf , the ground state entropy is
dominant. For the BEC case we suggest a phenomenological model to build up colored
bosonic quark pairs. Here the entropy entirely depends upon the short ranged repulsive
interactions between the quark pairs and vanishes for large momenta. |
