Determination of the intrinsic mechanical quality factor in high-stress silicon nitride resonators
Geena Benga, Vincent Dumont, Wei Wang +6
Recent advances in silicon nitride nanomechanical resonators have pushed mechanical quality factors to ultra-high values by combining stress-induced dissipation dilution with mode-…
Near-resonant nuclear spin detection with megahertz mechanical resonators
Diego A. Visani, Letizia Catalini, Christian L. Degen +2
Mechanical resonators operating in the megahertz range have become a versatile platform for fundamental and applied quantum research. Their exceptional properties, such as low mass…
From Cantilevers to Membranes: Advanced Scanning Protocols for Magnetic Resonance Force Microscopy
Nils Prumbaum, Christian L. Degen, Alexander Eichler
Magnetic Resonance Force Microscopy (MRFM) enables three-dimensional imaging of nuclear spin densities in nanoscale objects. Based on numerical simulations, we evaluate the perform…
On-Chip Frequency Noise Cancellation in Nanomechanical Resonators using Cavity Optomechanics
Bhavesh Kharbanda, Amirali Arabmoheghi, Letizia Catalini +7
Understanding and minimizing the sources of frequency noise in nanomechanical resonators is crucial for many sensing applications. In this work, we report an ultracoherent perimete…
Differential Magnetic Force Microscopy with a Switchable Tip
Shobhna Misra, Reshma Peremadathil Pradeep, Yaoxuan Feng +5
The separation of physical forces acting on the tip of a magnetic force microscope (MFM) is essential for correct magnetic imaging. Electrostatic forces can be modulated by varying…
