Nanomechanical Detection of Itinerant Electron Spin Flip
Guiti Zolfagharkhani, Alexei Gaidarzhy, Pascal Degiovanni +3
Spin is an intrinsically quantum property, characterized by angular momentum. A change in the spin state is equivalent to a change in the angular momentum or mechanical torque. Thi…
Model of response spectrum and modal interaction in coupled nanomechanical resonators
J. Dorignac, A. Gaidarzhy, P. Mohanty
We develop a simple continuum model to analyze the vibrational modes of a nanomechanical multi-element structure. In this model, arrays of sub-micron cantilevers located symmetrica…
High quality factor gigahertz frequencies in nanomechanical diamond resonators
Alexei Gaidarzhy, Matthias Imboden, Pritiraj Mohanty +2
We report actuation and detection of gigahertz-range resonance frequencies in nano-crystalline diamond mechanical resonators. High order transverse vibration modes are measured in…
Scaling of dissipation in megahertz-range micromechanical diamond oscillators
Matthias Imboden, Pritiraj Mohanty, Alexei Gaidarzhy +2
We report frequency and dissipation scaling laws for doubly-clamped diamond resonators. The device lengths range from 10 microns to 19 microns corresponding to frequency and qualit…
Quantum Friction in Nanomechanical Oscillators at Millikelvin Temperatures
Guiti Zolfagharkhani, Alexei Gaidarzhy, Seung-Bo Shim +2
We report low-temperature measurements of dissipation in megahertz-range, suspended, single-crystal nanomechanical oscillators. At millikelvin temperatures, both dissipation (inver…
Signal Processing and Control in Nonlinear Nanomechanical Systems
R. L. Badzey, G. Zolfagharkhani, S. -B. Shim +2
Bestriding the realms of classical and quantum mechanics, nanomechanical structures offer great promise for a huge variety of applications, from computer memory elements \cite{badz…
