Branching states as the emergent structure of a quantum universe
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 …

Detailed fluctuation theorem from the one-time measurement scheme
We study the quantum fluctuation theorem in the one-time measurement (OTM) scheme,
where the work distribution of the backward process has been lacking and which is …

Exchange fluctuation theorems for strongly interacting quantum pumps
We derive a general quantum exchange fluctuation theorem for multipartite systems with
arbitrary coupling strengths by taking into account the informational contribution of the back …
