Robinjeet Singh (Assoc)

Robinjeet Singh is a Research Associate through PREP program between NIST and the University of Colorado, Boulder. He is associated with the Quantum Sensor Group of the Physical Measurement Laboratory at NIST. His current research interests include design and microfabrication of Superconducting Quantum Interface Devices (SQUIDs) and other novel superconducting sensors for observational cosmology and astronomy applications.

Before joining NIST Boulder, he was a postdoctoral associate in the Quantum Optics Group at NIST, Gaithersburg. As a postdoctoral associate, he advanced experimental and microfabrication efforts to develop optomechanical systems for temperature metrology and quantum information transduction applications.

For his PhD research at the Louisiana State University, as a part of LIGO Science Collaboration, he developed table-top test experiments to measure quantum effects in a microresonator based cavity optomechanical systems. His research work was in part an effort to understand and test quantum noise evasion for the next generation upgrades to the US based gravitational wave detectors (advanced LIGO).

Optomechanical Pressure Measurement System And Method Using The Vibrational Modes Of A Membrane

NIST Inventors
Stephen Eckel , James A. Fedchak , Thomas Purdy and Robinjeet Singh
An optomechanical pressure-measurement system measures pressure in the range of 10.sup.−6 Pa-10.sup.−2 Pa by measuring various properties of a vibrational mode of an ultra-thin membrane member. With independent measurements of the thickness and density of the membrane, in addition to the measured
