Group seminar at MPQ & via Zoom: Smart microscopy: automated control of cellular activity in space and time

Cellular activity can be controlled with light-induced stimulation of molecular processes through engineered photoreceptor proteins. While these optogenetic tools have been used mainly ‘ad hoc’, we aimed to integrate them into a feedback system that uses live microscopy images more

Group Seminar at MPQ and via Zoom: Pyramid MOT: A Compact High Flux Cold Atom Source

The discovery of Magneto Optical Trapping has had a profound impact on experimental physics, and is one of the key discoveries driving the current second quantum revolution. In this talk I will discuss the implementation of a Pyramid MOT as a cold atom more

Group Seminar at MPQ & via Zoom: Fault-Tolerant Quantum Error Correction: From Concepts to Experiments

To date, the construction of a scalable fault-tolerant quantum computer remains a fundamental scientific and technological challenge, due to the influence of unavoidable noise. In the seminar, I will introduce basic concepts of quantum error correction more

Group Seminar at LMU & via Zoom: Towards spin squeezing in real clocks

I will start by presenting recent results of a collaboration between my group at Laboratoire Kastler Brossel and SYRTE (the French time and frequency metrology lab), where we have produced spin squeezed states of ultracold Rb atoms

Group Seminar at MPQ & via Zoom: Probing optical signatures of quasiparticles in two-dimensional semiconductors

Transition metal dichalcogenide (TMD) monolayers are a widely investigated two-dimensional semiconductor. Their band structures have a direct band gap, which favors optical transitions. Furthermore, the electronic properties more

Group Seminar via Zoom: Many-body dynamics of ultracold polar molecules in an optical lattice

Following recent advances in the manipulation of atomic, molecular and optical systems, quantum simulators of strongly-correlated many-body lattice models have been realized on a number of experimental platforms, including ultracold gases of neutral atoms and polar molecules, as well as Rydberg atom arrays and trapped ions. In particular, ultracold polar molecules confined in optical lattices provide more

Group Seminar at LMU & Zoom: Ultralong-range Rydberg molecules

Long-range Rydberg molecules are molecules in highly-excited electronic states where the binding results from the scattering of an almost free electron from neutral atoms within its orbit. The existence of such bound states was first predicted by Greene and coworkers in 2000 more
