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…
The time of arrival problem in the Page-Wootters formalism
Niyusha Hosseini, Maximilian P. E. Lock
The time-of-arrival problem asks for the probability distribution for when a quantum particle reaches a specified location. It has been the subject of decades of debate, exemplifyi…
Average Equilibration Time for Gaussian Unitary Ensemble Hamiltonians
Emanuel Schwarzhans, Alessandro Candeloro, Felix C. Binder +2
Understanding equilibration times in closed quantum systems is essential for characterising their approach to equilibrium. Chaotic many-body systems are paradigmatic in this contex…
Relational Dynamics with Periodic Clocks
Leonardo Chataignier, Philipp A. Hoehn, Maximilian P. E. Lock +1
We discuss a systematic way in which a relational dynamics can be established relative to periodic clocks both in the classical and quantum theories, emphasising the parallels betw…
Time delocalization and causality across temporal quantum reference frames
Veronika Baumann, Maximilian P. E. Lock
In relational quantum dynamics, evolution emerges via the correlations between some system of interest and a clock system, which plays the role of a temporal reference frame. Their…
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…
