Modelling quantum measurement dynamics: from decoherence to redundancy with site-hopping indistinguishable particles
Katja Schneeweiss, Tom Rivlin, Maximilian P. E. Lock +2
In recent years, new theoretical insights into decoherence and quantum measurements have emerged through the study of many-body dynamics in isolated quantum systems. It is now unde…
Emergence of Classicality in Wigner's Friend Scenarios
Tom Rivlin, Sophie Engineer, Veronika Baumann
The Wigner's Friend (WF) thought experiment concerns quantum measurements by a 'superobserver' of an observer measuring a quantum system. Variations on the setup and its extended v…
Emergence of a second law of thermodynamics in isolated quantum systems
Florian Meier, Tom Rivlin, Tiago Debarba +3
The second law of thermodynamics states that the entropy of an isolated system can only increase over time. This appears to conflict with the reversible evolution of isolated quant…
Equilibration of objective observables in a dynamical model of quantum measurements
Sophie Engineer, Tom Rivlin, Sabine Wollmann +2
The challenge of understanding quantum measurement persists as a fundamental issue in modern physics. Particularly, the abrupt and energy-non-conserving collapse of the wave functi…
