Information

Ziele, Inhalte und Methode der Lehrveranstaltung

The goal of this lecture is to provide a comprehensive overview of tests of quantum physics on the macroscopic scale - i.e., tests of quantum physics with macroscopic masses and/or over macroscopic distances. The lecture will provide a rview of historical developments, the motivation behind experimental tests of quantum physics, and a discussion of the limitations of state-of-the-art tests and venues to overcome these limitations in proposed future experiments.

* Quantum measurement problem, possible limitations of quantum physics
* Environmental decoherence & isolation from the environment
* Possible deviations from quantum physics (Collapse models, Macrorealism, Deviations due to gravity or new physics)
* heating of center-of-mass motion
* matter-wave interference
* quantum optomechanics and its use for fundamental tests
* gravitational decoherence of massive superpositions
* gravitational decoherence of entanglement
* Rotational revival and rotational alignment decay
* experimental limitations
- imperfect isolation (blackbody radiation, scattering of particles)
- vibrations
- limited statistics
- limited free-fall time
* proposals for future experiments

Art der Leistungskontrolle und erlaubte Hilfsmittel

Participation during the course and a final oral exam. Possible times and the place for the exam will be put online soon. Lecture materials will be made available online via moodle.

Mindestanforderungen und Beurteilungsmaßstab

Students should have completed the following courses:
Introduction to Physics I-IV
Theoretical Physics I-II

Prüfungsstoff

During the oral exam, I will ask questions about the whole content of the lecture, but I will focus on getting a grasp on whether the student has understood the underlying concepts. I will not ask for ad-hoc derivations or calculations.
