A Renormalizable SYK-type Tensor Field Theory

Understand

In this paper we introduce a simple field theoretic version of the Carrozza-Tanasa-Klebanov-Tarnopolsky (CTKT) "uncolored" holographic tensor model.

• It gives a more familiar interpretation to the previously abstract modes of the SYK or CTKT models in terms of momenta.
• We choose for the tensor propagator the usual Fermionic propagator of condensed matter, with a spherical Fermi surface, but keep the CTKT interactions.
• Hence our field theory can also be considered as an ordinary condensed matter model with a non-local and non-rotational invariant interaction.
