Electric-field-controlled cold dipolar collisions between trapped CHF molecules
M. Koller, F. Jung, J. Phrompao +3
Reaching high densities is a key step towards cold-collision experiments with polyatomic molecules. We use a cryofuge to load up to 2 CHF molecules into a box-like…
Buffer-gas cooling of molecules in the low-density regime: Comparison between simulation and experiment
Thomas Gantner, Manuel Koller, Xing Wu +2
Cryogenic buffer gas cells have been a workhorse for the cooling of molecules in the last decades. The straightforward sympathetic cooling principle makes them applicable to a huge…
A cryofuge for cold-collision experiments with slow polar molecules
Xing Wu, Thomas Gantner, Manuel Koller +3
Ultracold molecules represent a fascinating research frontier in physics and chemistry, but it has proven challenging to prepare dense samples at low velocities. Here we present a…
Non-linear two-photon resonance fluorescence on a single artificial atom
P. -L. Ardelt, M. Koller, T. Simmet +7
We report two-photon resonance fluorescence of an individual semiconductor artificial atom. By non-linearly driving a single quantum dot via a two-photon transition, we probe the l…
Dissipative preparation of the exciton and biexciton in a self-assembled quantum dot on picosecond timescales
Per-Lennart Ardelt, Lukas Hanschke, Kevin A. Fischer +9
Pulsed resonant fluorescence is used to probe ultrafast phonon-assisted exciton and biexciton preparation in individual self-assembled InGaAs quantum dots. By driving the system us…
