Shockwaves from the Operator Product Expansion
Nima Afkhami-Jeddi, Thomas Hartman, Sandipan Kundu +1
We clarify and further explore the CFT dual of shockwave geometries in Anti-de Sitter. The shockwave is dual to a CFT state produced by a heavy local operator inserted at a complex…
Constraints on Higher Spin CFT
Nima Afkhami-Jeddi, Kale Colville, Thomas Hartman +2
We derive constraints on two-dimensional conformal field theories with higher spin symmetry due to unitarity, modular invariance, and causality. We focus on CFTs with $\mathcal{W}_…
An upper bound on transport
Thomas Hartman, Sean A. Hartnoll, Raghu Mahajan
The linear growth of operators in local quantum systems leads to an effective lightcone even if the system is non-relativistic. We show that consistency of diffusive transport with…
From Conformal Blocks to Path Integrals in the Vaidya Geometry
Tarek Anous, Thomas Hartman, Antonin Rovai +1
Correlators in conformal field theory are naturally organized as a sum over conformal blocks. In holographic theories, this sum must reorganize into a path integral over bulk field…
