State Diagnostics of Complexity in Open Quantum Systems
Komal Sah, Fabio Anza, Alexandra M. Jurgens +1
We study the emergence of complexity in finite-size quantum systems as their dynamics transition from closed and coherent evolution to interacting and effectively open behavior. Us…

Observable Statistical Mechanics
Lodovico Scarpa, Abdulla Alhajri, Vlatko Vedral +1
Predicting the stationary behavior of observables in isolated many-body quantum systems is a central challenge in quantum statistical mechanics. While one can often use the Gibbs e…

Branching States as The Emergent Structure of a Quantum Universe
Akram Touil, Fabio Anza, Sebastian Deffner +1
Quantum Darwinism builds on decoherence theory to explain the emergence of classical behavior in a fundamentally quantum universe. Within this framework we prove two crucial insigh…
