Precise estimation of the coupling strength between two nanomechanical modes from four Ramsey fringes
Anh Tuan Le, Avishek Chowdhury, Hugo Ribeiro +1
We experimentally determine the coupling strength between two strongly coupled nanomechanical modes using a Ramsey-inspired technique optimized for signals as short as four fringes…
Fundamental and second-subharmonic Autler-Townes splitting in classical systems
Ahmed A. Barakat, Avishek Chowdhury, Anh Tuan Le +1
The dynamic Stark effect and the Autler-Townes splitting (ATS) are hallmarks of driven two-level systems. We establish a direct correspondence between these quantum phenomena and t…
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…
Room temperature cavity electromechanics in the sideband-resolved regime
Anh Tuan Le, Alexandre Brieusssel, Eva Maria Weig
We demonstrate a sideband-resolved cavity electromechanical system operating at room temperature. The mechanical resonator, a strongly pre-stressed silicon nitride string, is diele…
