Information

Aims, contents and method of the course

Goal of this lecture is to provide a comprehensive review 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 an overview historical developments, the motivation behind experimental tests of quantum physics and a discussion of the limitations of such 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)
* 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, gas collisions)
- vibrations
- limited statistics
- limited free-fall time
* proposals for future experiments
