Caustics bounding entanglement wedges
Marine De Clerck, Charles Rabideau, Niklas Tanger
We study the caustics on the boundaries of entanglement wedges in the context of holography in asymptotically AdS spacetimes. These entanglement wedges play an important role i…

Superluminal chaos after a quantum quench
Vijay Balasubramanian, Ben Craps, Marine De Clerck +1
Thermal states holographically dual to black holes in Einstein gravity display maximal Lyapunov growth as well as "butterfly effect cones". We study these effects in highly non-equ…

Lyapunov growth in quantum spin chains
Ben Craps, Marine De Clerck, Djunes Janssens +2
The Ising spin chain with longitudinal and transverse magnetic fields is often used in studies of quantum chaos, displaying both chaotic and integrable regions in its parameter spa…
