SYK collective field theory as complex Liouville gravity
Andreas Blommaert, Damiano Tietto, Herman Verlinde
We establish a precise relationship between the collective field theory of the double scaled SYK model and the worldsheet theory of the complex Liouville string a.k.a. sine di…

The power of Lorentzian wormholes
Andreas Blommaert, Jorrit Kruthoff, Shunyu Yao
As shown by Louko and Sorkin in 1995, topology change in Lorentzian signature involves spacetimes with singular points, which they called crotches. We modify their construction to…
