| Unqenched Holographic Magnetic Catalysis |
| Speaker: | Veselin Filev (MPI Munich) |
| Abstract: | We propose a string dual to the SU(N_c) N=4 SYM coupled to massless
fundamental flavors in an external magnetic field. The flavors are
introduced by partially smeared Nf D7 branes and the external magnetic
field via non-trivial Kalb-Rammond B-field. We introduce an additional probe
D-brane which couples to the background B-field and study the influence of
the
backreacted flavors on the effect of mass generation. At sufficiently
strong magnetic fields the meson spectrum signals an instability of the
probe
which we interpret as reflecting an instability of the background.
We report also on a very recent progress with backreacted massive flavor
branes.
