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.…

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…

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 backre…

Worldsheet from worldline

Umut Gursoy, Guim Planella Planas

We take a step toward a "microscopic" derivation of gauge-string duality. In particular, using mathematical techniques of Strebel differentials and discrete exterior calculus, we o…

Holographic entanglement as nonlocal magnetism

Umut Gürsoy, Juan F. Pedraza, Guim Planella Planas

The Ryu-Takayanagi prescription can be cast in terms of a set of microscopic threads that help visualize holographic entanglement in terms of distillation of EPR pairs. While this…
