A bstractHomogeneous, zero temperature scaling solutions with Bianchi VII spatial geometry are constructed in Einstein-Maxwell-Dilaton theory. They correspond to quantum critical saddle points with helical symmetry at finite density. Assuming AdS5 UV asymptotics, the small frequency/(temperature) dependence of the AC/(DC) electric conductivity along the director of the helix are computed. A large class of insulating and conducting anisotropic phases is found, as well as isotropic, metallic phases. Conduction can be dominated by dissipation due to weak breaking of translation symmetry or by a quantum critical current.

Dissecting holographic conductivities (2015, background): “In theories where there is a neutral scalar which can run logarithmically in the interior of the geometry [16, 17, 19], we would expect that the temperature scalings of the coherent and incoherent contributions to the conductivities can be different from one another.”
