Quantum dynamics of systems featuring long sequences of events

Date: Monday, April 23, 2018 16:00 - 17:00
Speaker: Jürg Fröhlich (ETH Zurich)
Location: Raiffeisen Lecture Hall, Central Building
Series: Institute colloquium
Host: Laszlo Erdös
Contact: ZARUBA Katharina
Central building lecture hall

Abstract:

The purpose of this lecture is to explain how, in quantum mechanics, interesting information about a physical system can be reconstructed from long streams of data concerning primitive events featured by the system.

Examples of experiments on concrete systems, such as experiments measuring the number of photons trapped in a cavity, conducted at the Ecole Normale Suprieure in Paris, will be considered. A brief sketch of a new approach to understanding the appearance of particle tracks - "Mott tracks" - in suitably chosen detectors will be presented.

The lecture will end with remarks on the meaning of events and on the time evolution of states, as described by the "ETH approach to Quantum Mechanics".
