Arrival time distributions and spin in quantum mechanics-A Bohmian perspective (Siddhant Das)

Datum: 07.11.2018
Uhrzeit: 10:30
Vortragende(r): Siddhant Das
Ludwig-Maximilians-Universität (LMU) München
Ort: Max-Planck-Institut für Quantenoptik
Raum: New Lecture Hall, Room B 0.32
Gastgeber: MPQ, Theory Division

The arrival time statistics of spin-1/2 particles governed by Pauli's equation, and defined by their Bohmian trajectories, show unexpected and very well articulated features. Comparison with other proposed statistics of arrival times that arise from either the usual (convective) quantum flux or from semiclassical considerations suggests testing the notable deviations in an arrival time experiment, thereby probing the predictive power of Bohmian trajectories. The suggested experiment, including the preparation of the wave functions, could be done with present-day experimental technology. [mehr]
