Achieving Sub-Zeptonewton Force Sensitivity and Spin-Motion Entanglement in Levitated Diamond via Pulsed Backaction Evasion
Gayathrini Premawardhana, Jonathan Beaumariage, M. V. Gurudev Dutt +3
We propose a system to achieve sub-zeptonewton force sensing and robust spin-mechanical entanglement in a levitated diamond system. By coupling a nitrogen-vacancy (NV) center spin…
Nanofabricated torsion pendulums for tabletop gravity experiments
Jack Manley, Charles A. Condos, Zachary Fegley +5
Measurement of mutual gravitation on laboratory scales is an outstanding challenge and a prerequisite to probing theories of quantum gravity. A leading technology in tabletop gravi…
Entanglement witness for combined atom interferometer-mechanical oscillator setup
Gayathrini Premawardhana, Deven P. Bowman, Jacob M. Taylor
We investigate how to entangle an atom interferometer and a macroscopic mechanical oscillator in order to create non-classical states of the oscillator. We propose an entanglement…
Feasibility of a trapped atom interferometer with accelerating optical traps
Gayathrini Premawardhana, Jonathan Kunjummen, Sarthak Subhankar +1
In order to increase the measured phase of an atom interferometer and improve its sensitivity, researchers attempt to increase the enclosed space-time area using two methods: creat…
Energy and RF Cavity Phase Symmetry Enforcement in Multi-turn ERL Models
Rosalyn Koscica, Nilanjan Banerjee, Georg Heinz Hoffstaetter +2
In a multipass energy recovery linac (ERL), each cavity must regain all energy expended from beam acceleration during beam deceleration, and the beam should achieve specific energy…
