Boundary Condition dependent Universality Classes on a Hyperbolic Lattice
Pallabi Dey, Debasish Banerjee, Arnab Kundu +1
We study the ferromagnetic Ising model on finite hyperbolic tessellations of Euclidean AdS with open and wired boundary conditions. Because a finite fraction of spins remains a…
What is the Simplest Linear Ramp?
Suman Das, Sumit K. Garg, Chethan Krishnan +1
We discuss conditions under which a deterministic sequence of real numbers, interpreted as the set of eigenvalues of a Hamiltonian, can exhibit features usually associated to rando…
State Dependence of Krylov Complexity in CFTs
Arnab Kundu, Vinay Malvimat, Ritam Sinha
We compute the Krylov Complexity of a light operator in an eigenstate of a CFT at large central charge . The eigenstate corresponds to a primary operator $\…
Fuzzballs and Random Matrices
Suman Das, Sumit K. Garg, Chethan Krishnan +1
Black holes are believed to have the fast scrambling properties of random matrices. If the fuzzball proposal is to be a viable model for quantum black holes, it should reproduce th…
Brane Detectors of a Dynamical Phase Transition in a Driven CFT
Suchetan Das, Bobby Ezhuthachan, Arnab Kundu +3
We show that a dynamical transition from a non-heating to a heating phase of a periodic driven two-dimensional conformal field theory (CFT) with a large central…
Synthetic Fuzzballs: A Linear Ramp from Black Hole Normal Modes
Suman Das, Chethan Krishnan, A. Preetham Kumar +1
We consider a black hole with a stretched horizon as a toy model for a fuzzball microstate. The stretched horizon provides a cut-off, and therefore one can determine the normal (as…
