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…
Toy Model Challenging Prevailing Definitions of Classicality
Irene Valladares Duque, Philipp Strasberg
We analyze a toy model that obeys environmentally induced decoherence and quantum Darwinism and satisfies the decoherent histories criterion and Leggett-Garg inequalities with resp…
Decoherence of Histories: Chaotic Versus Integrable Systems
Jiaozi Wang, Philipp Strasberg
We study the emergence of decoherent histories in isolated systems based on exact numerical integration of the Schrödinger equation for a Heisenberg chain. We reveal that the natu…
Typical Positivity of Nonequilibrium Entropy Production for Pure States
Philipp Strasberg, Joseph Schindler
We establish that the nonequilibrium dynamics of most pure states gives rise to the same entropy production as that of the corresponding ensemble, provided the effective dimension…
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…
