High-resolution spectroscopy of a single nitrogen-vacancy defect at zero magnetic field
Shashank Kumar, Pralekh Dubey, Sudhan Bhadade +3
We report a study of high-resolution microwave spectroscopy of nitrogen-vacancy centers in diamond crystals at and around zero magnetic field. We observe characteristic splitting a…
Scalable fabrication of single silicon vacancy defect arrays in silicon carbide using focused ion beam
Junfeng Wang, Xiaoming Zhang, Yu Zhou +8
In this work, we present a method for targeted, maskless, and scalable fabrication of single silicon vacancy (VSi) defect arrays in silicon carbide (SiC) using focused ion beam. Th…
Nanomechanical sensing using spins in diamond
Michael S. J. Barson, Phani Peddibhotla, Preeti Ovartchaiyapong +15
Nanomechanical sensors and quantum nanosensors are two rapidly developing technologies that have diverse interdisciplinary applications in biological and chemical analysis and micr…
Boundary between the thermal and statistical polarization regimes in a nuclear spin ensemble
B. E. Herzog, D. Cadeddu, F. Xue +2
As the number of spins in an ensemble is reduced, the statistical uctuations in its polarization eventually exceed the mean thermal polarization. This transition has now been surpa…
Harnessing nuclear spin polarization fluctuations in a semiconductor nanowire
P. Peddibhotla, F. Xue, H. I. T. Hauge +3
Soon after the first measurements of nuclear magnetic resonance (NMR) in a condensed matter system, Bloch predicted the presence of statistical fluctuations proportional to $1/\sqr…
Feedback cooling of cantilever motion using a quantum point contact transducer
M. Montinaro, A. Mehlin, H. S. Solanki +4
We use a quantum point contact (QPC) as a displacement transducer to measure and control the low-temperature thermal motion of a nearby micromechanical cantilever. The QPC is inclu…
A geometry for optimizing nanoscale magnetic resonance force microscopy
Fei Xue, P. Peddibhotla, M. Montinaro +2
We implement magnetic resonance force microscopy (MRFM) in an experimental geometry, where the long axis of the cantilever is normal to both the external magnetic field and the RF…
