19 Sep 2013 | | Abstract: | We study the phase diagram of a holographic model realizing a U(2) global
symmetry on the boundary and show that at low temperature a phase with both
scalar s and vector p condensates exists. This is the s+p-wave phase where the
global U(2) symmetry and also the spatial rotational symmetry are spontaneously
broken. By studying the free energy we show that this phase is preferred when
it exists. We also consider unbalanced configurations where a second chemical
potential is turned on. They present a rich phase diagram characterized by the
competition and coexistence of the s and p order parameters. | | Source: | arXiv, 1309.5086 | | Services: | Forum | Review | PDF | Favorites | |
