JT gravity on the worldline
Ben Freivogel, Alessandro Fumagalli, Diego M. Hofman
Motivated by the problem of understanding the experience of an observer in dynamical quantum gravity, we study the effects of coupling a one-dimensional quantum mechanical system l…
The Phases of Chaos
Tarek Anous, Diego M. Hofman
We develop a novel physical picture to understand certain universal properties of the GUE matrix model which are typically ascribed to quantum chaos, i.e. the ramp and the plateau.…
Generalised symmetries and state-operator correspondence for nonlocal operators
Diego M. Hofman, Stathis Vitouladitis
We provide a one-to-one correspondence between line operators and states in four-dimensional CFTs with continuous 1-form symmetries. In analogy with 0-form symmetries in two dimens…
Gravity as a gapless phase and biform symmetries
Kurt Hinterbichler, Diego M. Hofman, Austin Joyce +1
We study effective field theories (EFTs) enjoying (maximal) biform symmetries. These are defined by the presence of a conserved (electric) current that has the symmetries of a Youn…
One-dimensional Quantum Gravity and the Schwarzian theory
Dionysios Anninos, Diego M. Hofman, Stathis Vitouladitis
We develop a model of one-dimensional (Conformal) Quantum Gravity. By discussing the connection between Goldstone and Gauge theories, we establish that this model effectively compu…
On the Stress Tensor Light-ray Operator Algebra
Alexandre Belin, Diego M. Hofman, Grégoire Mathys +1
We study correlation functions involving generalized ANEC operators of the form in four dimensions. We compute two, three, and fo…
