In this talk I will discuss new properties of the complex SYK model in comparison with the Majorana one. I’ll mostly focus on spectrum of operators and the effective low energy action of the complex SYK model. In this case the conserved U(1) charge contributes a compact scalar field to the effective action in addition to the Schwarzian term. Part of the Black Hole Information Paradox Journal Club.
