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…
