Hamburg Photon Science Colloquium | Cavities to strengthen the fractional quantum hall effect

by Jérôme Faist (ETH Zurich, Switzerland)

Friday 17 May 2024, 14:00 → 15:30 Europe/Berlin

SemR I-III (CFEL, Bldg. 99)

We have investigated a new experimental geometry where a hovering resonator is positioned with nanoactuators above the Hall bar, providing a way to continuously vary the light-matter coupling while the sample is maintained at millikelvin temperatures. Using this approach, we observe the effect of light-matter coupling on the effective electron g-factor as well as its effect on the gap of the Laughlin states.

Coffee, tea and cake will be served at 1:45 pm.
