Observation of quantum Hall interferometer phase jumps due to changing quasiparticle number
Marc P. Röösli, Lars Brem, Benedikt Kratochwil +10
We measure the magneto-conductance through a micron-sized quantum dot hosting about 500 electrons in the quantum Hall regime. In the Coulomb blockade, when the island is weakly cou…

Quantum dot thermometry at ultra-low temperature in a dilution refrigerator with a He immersion cell
Giorgio Nicolí, Peter Märki, Beat A. Bräm +7
Experiments performed at a temperature of a few millikelvin require effective thermalization schemes, low-pass filtering of the measurement lines and low-noise electronics. Here, w…

Temperature-stabilized differential amplifer for low-noise DC measurements
P. Märki, B. A. Braem, T. Ihn
A tabletop low-noise differential amplifer with a bandwidth of 100 kHz is presented. Low voltage drifts of the order of 100 nV/day are reached by thermally stabilizing relevant amp…
