Emergent Lorentz invariance with chiral fermions

We study the renormalization group flow in strongly interacting field theories in the fermion sector corresponding to the transition from theories without a Lorentz invariance at high energies to theories with an approximate Lorentz invariance in the infrared limit. We use the holographic description of the strong coupling. We give special attention to the emergence of chiral fermions in the low-energy limit.
