Analysis of membrane phononic crystals with wide bandgaps and low-mass defects
Chris Reetz, Ran Fischer, Gabriel G. T. Assumpcao +4
We present techniques to model and design membrane phononic crystals with low-mass defects, optimized for force sensing. Further, we identify the importance of the phononic crystal…
Spin detection with a micromechanical trampoline: Towards magnetic resonance microscopy harnessing cavity optomechanics
Ran Fischer, Dylan P. McNally, Chris Reetz +4
We explore the prospects and benefits of combining the techniques of cavity optomechanics with efforts to image spins using magnetic resonance force microscopy (MRFM). In particula…
Optical probing of mechanical loss of a Si_{3}N_{4} membrane below 100 mK
R. Fischer, N. S. Kampel, G. G. T. Assumpção +5
We report on low mechanical loss in a high-stress silicon nitride (Si_{3}N_{4}) membrane at temperatures below 100 mK. We isolate a membrane via a phononic shield formed within a s…
Improving broadband displacement detection with quantum correlations
N. S. Kampel, R. W. Peterson, R. Fischer +5
Interferometers enable ultrasensitive measurement in a wide array of applications from gravitational wave searches to force microscopes. The role of quantum mechanics in the metrol…
Local probing of nuclear bath polarization with a single electronic spin
Paz London, Ran Fischer, Ignacio Alvizu +2
We demonstrate experimentally that a polarized nuclear spin modifies the dynamic behavior of a neighboring electronic spin. Specifically, an out-of-phase component appears in the e…
Optically Detected Magnetic Resonance Imaging
Aharon Blank, Guy Shapiro, Ran Fischer +2
Optically detected magnetic resonance (ODMR) provides ultrasensitive means to detect and image a small number of electron and nuclear spins, down to the single spin level with nano…
Local and bulk 13C hyperpolarization in NV-centered diamonds at variable fields and orientations
Gonzalo A. Alvarez, Christian O. Bretschneider, Ran Fischer +6
Polarizing nuclear spins is of fundamental importance in biology, chemistry and physics. Methods for hyperpolarizing 13C nuclei from free electrons in bulk, usually demand operatio…
Time-Optimal Universal Control of Two-Level Systems under Strong Driving
Chen Avinadav, Ran Fischer, Paz London +1
We experimentally study the time-optimal construction of arbitrary single-qubit rotations under a single strong driving field of finite amplitude. Using radiation-dressed states of…
Detecting and polarizing nuclear spins with double resonance on a single electron spin
P. London, J. Scheuer, J. -M. Cai +11
We report the detection and polarization of nuclear spins in diamond at room temperature by using a single nitrogen-vacancy (NV) center. We use Hartmann-Hahn double resonance to co…
The Infrared Absorption Band and Vibronic Structure of the Nitrogen-Vacancy Center in Diamond
P. Kehayias, M. W. Doherty, D. English +7
Negatively-charged nitrogen-vacancy (NV) color centers in diamond have generated much interest for use in quantum technology. Despite the progress made in developing their appl…
Bulk Nuclear Polarization Enhanced at Room-Temperature by Optical Pumping
Ran Fischer, Christian O. Bretschneider, Paz London +3
Bulk 13C polarization can be strongly enhanced in diamond at room-temperature based on the optical pumping of nitrogen-vacancy color centers. This effect was confirmed by irradiati…
Gyroscopes based on nitrogen-vacancy centers in diamond
Micah Ledbetter, Kasper Jensen, Ran Fischer +2
We propose solid-state gyroscopes based on ensembles of negatively charged nitrogen-vacancy () centers in diamond. In one scheme, rotation of the nitrogen-vacancy symme…
Optical polarization of nuclear ensembles in diamond
Ran Fischer, Andrey Jarmola, Pauli Kehayias +1
We report polarization of a dense nuclear-spin ensemble in diamond and its dependence on magnetic field and temperature. The polarization method is based on the transfer of electro…
