Free Nano-Object Ramsey Interferometry for Large Quantum Superpositions
C. Wan, M. Scala, G. W. Morley +6
We propose an interferometric scheme based on an untrapped nano-object subjected to gravity. The motion of the center of mass (c.m.) of the free object is coupled to its internal s…
Burning and graphitization of optically levitated nanodiamonds in vacuum
A. T. M. A. Rahman, A. Frangeskou, M. S. Kim +3
A nitrogen-vacancy (NV) center in a nanodiamond, levitated in high vacuum, has recently been proposed as a probe for demonstrating mesoscopic center-of-mass superpositions \cit…
Tolerance in the Ramsey interference of a trapped nanodiamond
C. Wan, M. Scala, S. Bose +5
The scheme recently proposed in [M. Scala et al., Phys Rev Lett 111, 180403 (2013)], where a gravity-dependent phase shift is induced on the spin of a nitrogen-vacancy (NV) center…
Simultaneous cooling of coupled mechanical oscillators using whispering gallery mode resonances
Ying Lia Li, James Millen, P. F. Barker
We demonstrate simultaneous center-of-mass cooling of two coupled oscillators, consisting of a microsphere-cantilever and a tapered optical fiber. Excitation of a whispering galler…
Testing Wavefunction Collapse Models using Parametric Heating of a Trapped Nanosphere
Daniel Goldwater, Mauro Paternostro, P. F. Barker
We propose a mechanism for testing the theory of collapse models such as continuous spontaneous localization (CSL) by examining the parametric heating rate of a trapped nanosphere.…
Macroscopic quantum resonators (MAQRO): 2015 Update
Rainer Kaltenbaek, Markus Arndt, Markus Aspelmeyer +49
Do the laws of quantum physics still hold for macroscopic objects - this is at the heart of Schrödinger's cat paradox - or do gravitation or yet unknown effects set a limit for mas…
