A Numerical Study of Chaotic Dynamics of K-S Equation with FNOs
Surbhi Khetrapal, Jaswin Kasi
Solving non-linear partial differential equations which exhibit chaotic dynamics is an important problem with a wide-range of applications such as predicting weather extremes and f…
Mutual information scrambling in Ising spin chain
Surbhi Khetrapal, Emil Tore Mærsk Pedersen
We consider a chain of spin-half particles of a finite length, evolved with the mixed-field Ising Hamiltonian and impose open boundary condition. We simulate the time evolution of…
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…
Energy level splitting for weakly interacting bosons in a harmonic trap
Ben Craps, Marine De Clerck, Oleg Evnin +1
We consider identical quantum bosons with weak contact interactions in a two-dimensional isotropic harmonic trap. When the interactions are turned off, the energy levels are equidi…
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.…
Boundary Term Contribution to the Volume of a Small Causal Diamond
Surbhi Khetrapal, Sumati Surya
In his calculation of the spacetime volume of a small Alexandrov interval in 4 dimensions Myrheim introduced a term which he referred to as a surface integral [1]. The evaluation o…
