Physics Group Meeting

In the presence of strong magnetic fields, the QCD vacuum may become unstable towards condensation of charged rho mesons, forming a superconducting state. I will talk about our investigation of this possible instability in a well-known holographic QCD model called the Sakai-Sugimoto model. Rho meson condensation occurs in this model at very high values of the magnetic field, possibly present during the cosmological electroweak phase transition or in heavy ion collisions at the LHC.
