Phase diagram of the D3/D5 system in a magnetic field and a BKT transition

Understand

We study the full temperature and chemical potential dependence of the D3/D5 2+1 dimensional theory in the presence of a magnetic field.

• The theory displays separate transitions associated with chiral symmetry breaking and melting of the bound states.
• We display the phase diagram which has areas with first and second order transitions meeting at two critical points similar to that of the D3/D7 system.
• In addition there is the recently reported BKT transition at zero temperature leading to distinct structure at low temperatures.
