Chaos and operator growth in 2d CFT
Surbhi Khetrapal
We study the out-of-time-ordered correlator (OTOC) in a zero temperature two dimensional conformal field theory (CFT) under evolution by a Liouvillian composed of the Virasoro gene…
Chaos in CFT dual to rotating BTZ
Ben Craps, Surbhi Khetrapal, Charles Rabideau
We compute out-of-time-order correlators (OTOCs) in two-dimensional holographic conformal field theories (CFTs) with different left- and right-moving temperatures. Depending on whe…
Chaos bound in Bershadsky-Polyakov theory
Justin R. David, Timothy J. Hollowood, Surbhi Khetrapal +1
We consider two dimensional conformal field theory (CFT) with large central charge c in an excited state obtained by the insertion of an operator Φwith large dimension Δ_Φ~ O(c) at…
Local quenches and quantum chaos from higher spin perturbations
Justin R. David, Surbhi Khetrapal, S. Prem Kumar
We study local quenches in 1+1 dimensional conformal field theories at large-c by operators carrying higher spin charge. Viewing such states as solutions in Chern-Simons theory, re…
Universal corrections to entanglement entropy of local quantum quenches
Justin R. David, Surbhi Khetrapal, S. Prem Kumar
We study the time evolution of single interval Renyi and entanglement entropies following local quantum quenches in two dimensional conformal field theories at finite temperature f…
Thermalization of Green functions and quasinormal modes
Justin R. David, Surbhi Khetrapal
We develop a new method to study the thermalization of time dependent retarded Green function in conformal field theories holographically dual to thin shell AdS Vaidya space times.…
