Towards holographic flat bands

A bstract Motivated by the phenomenology in condensed-matter flat-band Dirac systems, we here construct a holographic model that imprints symmetry breaking pattern of rather simple fermion at zero chemical potential. In bulk explicitly include backreaction to corresponding Lifshitz geometry and compute dynamical critical exponent. Most importantly, find such is unstable towards nematic phase, exhibiting an anomalous Hall effect featuring Drude-like shift its spectral weight. Our findings should motivate further studies quantum phases emerging from models.
