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

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

From Levitated Nanomagnets to Quantum Magnonics (Cosimo Carlo Rusconi)

From Levitated Nanomagnets to Quantum Magnonics (Cosimo Carlo Rusconi)
In this talk, I will present our results concerning how to describe and use the quantum degrees of freedom of a levitated nanomagnet. [mehr]
How does classical chaos affect the generation of quantum entanglement? What signatures of chaos exist at the quantum level and how can they be quantified? [mehr]
In two dimensions, Projected Entangled-Pair States (PEPS) are elegant many-body wavefunctions which capture efficiently the quantum entanglement of ground states of local quantum spin Hamiltonians. [mehr]
We model quantum transport through small interfaces weakly-coupled to two many-body leads under the Born approximation. [mehr]
