Holographic Models for Theories with Hyperscaling Violation

Understand

We study in detail a variety of gravitational toy models for hyperscaling-violating Lifshitz (hvLif) space-times.

• These space-times have been recently explored as holographic dual models for condensed matter systems.
• We start by considering a model of gravity coupled to a massive vector field and a dilaton with a potential.
• This model supports the full class of hvLif space-times and special attention is given to the particular values of the scaling exponents appearing in certain non-Fermi liquids.
