The Speed of Quantum Information Spreading in Chaotic Systems
Josiah Couch, Stefan Eccles, Phuc Nguyen +2
We present a general theory of quantum information propagation in chaotic quantum many-body systems. The generic expectation in such systems is that quantum information does not pr…

Holographic Purification Complexity
Elena Cáceres, Josiah Couch, Stefan Eccles +1
We study holographic subregion complexity, and its possible connection to purification complexity suggested recently by Agón et al. In particular, we study the conjecture that subr…

Holographic Complexity and Volume
Josiah Couch, Stefan Eccles, Ted Jacobson +1
The previously proposed "Complexity=Volume" or CV-duality is probed and developed in several directions. We show that the apparent lack of universality for large and small black ho…
