Title CFT1, Generalized SYK Models and Holographic Boundary Condition Changing Operators
Abstract Because there is no rotational symmetry in one dimension, two-point functions in CFT1 can be governed by two *distinct* critical exponents when t goes to plus or minus infinity. I will explain how this behaviour is found in natural generalizations of the standard complex SYK model and I will compute the associated critical exponents in this context. I will then introduce a new class of operators in holography, whose effect is to change the boundary conditions of bulk fields at the boundary of AdS, switching between so-called “standard” and “alternate” quantization schemes. In the case of AdS2/CFT1, these operators are local. I will explain how to compute their critical dimensions and argue that their two-point functions are governed in general by two distinct exponents.
