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…
A kinetic theory for quantum information transport
F. Anza
In this work we build a theoretical framework for the transport of information in quantum systems. This is a framework aimed at describing how out of equilibrium open quantum syste…
Quantifying the difference between many-body quantum states
Davide Girolami, Fabio Anzà
The quantum state overlap is the textbook measure of the difference between two quantum states. Yet, it is inadequate to compare the complex configurations of many-body systems. Th…
Logarithmic growth of local entropy and total correlations in many-body localized dynamics
Fabio Anza, Francesca Pietracaprina, John Goold
The characterizing feature of a many-body localized phase is the existence of an extensive set of quasi-local conserved quantities with an exponentially localized support. This str…
New equilibrium ensembles for isolated quantum systems
Fabio Anza
The unitary dynamics of isolated quantum systems does not allow a pure state to thermalize. Because of that, if an isolated quantum system equilibrates, it will do so to the predic…
