Shearing Off the Tree: Emerging Branch Structure and Born's Rule in an Equilibrated Multiverse
Philipp Strasberg, Joseph Schindler
Within the many worlds interpretation (MWI) it is believed that, as time passes on, the linearity of the Schrödinger equation together with decoherence generate an exponentially g…

Approximate Decoherence, Recoherence and Records in Isolated Quantum Systems
Philipp Strasberg, Joseph Schindler, Jiaozi Wang +1
Using the framework of decoherent histories, we study which past events leave detectable records in isolated quantum systems under the realistic assumption that decoherence is appr…

Unification of observational entropy with maximum entropy principles
Joseph Schindler, Philipp Strasberg, Niklas Galke +2
We introduce a definition of coarse-grained entropy that unifies measurement-based (observational entropy) and max-entropy-based (Jaynes) approaches to coarse-graining, by identify…
