Dynamics of Non-supersymmetric Flavours

Understand

We investigate the effect of the back-reaction by non-supersymmetric probes in the Kuperstein-Sonnenschein model.

• In the limit where the back-reaction is small, we discuss physical properties of the back-reacted geometry.
• We further introduce additional probe flavours in this back-reacted geometry and study in detail the phase structure of this sector when a constant electromagnetic field or a chemical potential are present.
• We find that the Landau pole, which serves as the UV cut-off of the background geometry, also serves as an important scale in the corresponding thermodynamics of the additional flavour sector.
