Emergent Strings from Quantum Field Theory
Guim Planella Planas
We develop a procedure that reorganizes the perturbative expansion in a class of quantum field theories into a stringy amplitude expressed as a sum over two-dimensional geometries.…
Mutual information from modular flow in CFTs
Cesar A. Agon, Horacio Casini, Umut Gürsoy +1
The operator product expansion (OPE) of twist operators in the replica trick framework enables a long-distance expansion of the mutual information (MI) in conformal field theories…
Perturbing a quantum black hole
Casey Cartwright, Umut Gürsoy, Juan F. Pedraza +1
We analyze the analytic structure of correlators in the field theory dual to the quantum Bañados-Teitelboim-Zanelli (qBTZ) black hole, a braneworld model incorporating exact backr…
Aspects of Entanglement Entropy in SCFTs
Pedro Vicente Marto, Umut Gürsoy, Guim Planella Planas
We investigate entanglement entropy in superconformal field theories from two different perspectives. We first confirm that the dependence of supersymmetric en…
