We plan to return partly to in-person talks. These talks will be held in the interim lecture hall B 0.32 at MPQ and can additionally be attended online. Some talks remain online only.

2G regulations apply to in-person talks, i.e. every time you wish to participate in person, you will have to prove, e.g. with the CovPass-App, that you are vaccinated or recovered.Whether facemasks have to be worn inside the lecture hall will be communicated in the the e-mail announcement for each talk separately. In any case, you will need a medical facemask in the hallway. Audience not affiliated with MPQ are welcome to join in person as long as they meet 2G criteria.

Details on how to participate online are distributed via the mailing lists [wiss-mpq] and [Mpq-colloquium-stream]. To receive this information, please register using the adjacent link.

Scientific organization of the talks:  Dr. Stephan Dürr and Dr. Thomas Udem

Room: B 0.32

Topological plasmonics: Ultrafast vector movies on the nanoscale (Prof. Harald Gießen)

We present an ultrafast vector microscope with 10 nm spatial and subfemtosecond temporal resolution which is capable of mapping all three vector components of the electric field as well as the magnetic field of light on nanophotonic structures. [more]

Quantum Photonics – from quantum computing to quantum foundations exploring the quantum-gravity interface (Prof. Philip Walther)

The precise quantum control of single photons, together with the intrinsic advantage of being mobile make optical quantum system ideally suited for various applications, reaching from quantum computing to precision measurements. [more]

Field-resolved microscopy: true time-domain views of light-matter interaction (Dr. Nick Karpowicz)

When charged particles move, they inscribe a history of their motion into an electromagnetic field, which carries it away from the origin. Recording various aspects of this light has been one of our main ways of investigating the fundamentals of nature for centuries, but directly observing the waveform has only become possible thanks to recent advances in ultrafast technology.

Electrons in 2D moiré superlattices (MCQST-Colloquium) (Prof. Jie Shan)

  • (in-person)
  • Date: Oct 26, 2021
  • Time: 14:30
  • Speaker: Prof. Jie Shan
  • Cornell University School of Applied and Engineering Physics, Ithaca/New York, USA
  • Room: B 0.32
When two van der Waals materials of slightly different orientations or lattice constants are overlaid, a moiré pattern emerges. The moiré pattern introduces a new length scale, many times the lattice constant of the original materials, for Bragg scattering of the Bloch electrons in each layer. This gives rise to moiré minibands and rich emergent quantum phenomena. [more]

+++ONLINE KOLLOQUIUM+++ Surprises from Time Crystals (Prof. Vedika Khemani)

Recent years have witnessed a remarkable confluence of diverse areas of physics coming together to inform fundamental questions about many-body quantum matter. A unifying theme in this enterprise has been the study of many-body quantum dynamics in systems ranging from electrons in solids to cold atomic gases to black holes. [more]
