A simple model for Hawking radiation

Abstract We consider n free Majorana fermions probing a SYK system comprising of N Majorana fermions. We solve the full system in deep infrared and in large N (as well as large n) limit. The essential physics of the SYK system is not affected by the probe Majoranas, except addition of another tower...

description Abstract We consider n free Majorana fermions probing a SYK system comprising of N Majorana fermions. We solve the full system in deep infrared and in large N (as well as large n) limit. The essential physics of the SYK system is not affected by the probe Majoranas, except addition of another tower of primaries. The SYK system is seen to induce maximal chaos as well as the whole spectrum of primaries, on to the probe system. The renormalization of soft mode action is computed. We comment on features in common with Hawking radiation.
