[phys4phys] Balkan String Webinar – March 6 13:30 CET – David Vegh

[Mihailo Čubrović]

Dear colleagues,

Next Friday, March 6,
at 13:30 CET (NOTICE THE TIME!),
David Vegh (Queen Mary University of London, UK) will give an online 
talk within the Balkan String Webinar series.

Title: A "folded string" dual for the Sachdev–Ye–Kitaev model

Abstract: We propose a "folded string" moving in rigid AdS2 with 
imaginary radius squared as a dual of the Sachdev–Ye–Kitaev (SYK) model 
at its conformal fixed point. In standard AdS2, the string is 
represented by two massless particles connected by straight string 
segments. The particles move at the speed of light, abruptly reversing 
direction at turning points. We describe the system using the lightcone 
coordinates of these points, with the Poisson structure obtained from 
the Peierls bracket. In AdS2 with imaginary radius squared, quantization 
of the string’s mass-squared in momentum-fraction space yields a 
Pöschl–Teller equation, reproducing the SYK operator spectrum.
