Determining Young's modulus via the eigenmode spectrum of a nanomechanical string resonator
Yannick S. Klaß, Juliane Doster, Maximilian Bückle +2
We present a method for the in-situ determination of Young's modulus of a nanomechanical string resonator subjected to tensile stress. It relies on measuring a large number of harm…

Iterative Adaptive Spectroscopy of Short Signals
Avishek Chowdhury, Anh Tuan Le, Eva M. Weig +1
We develop an iterative, adaptive frequency sensing protocol based on Ramsey interferometry of a two-level system. Our scheme allows one to estimate unknown frequencies with a high…
