Performance and limits of feedback cooling methods for levitated oscillators: a direct comparison
T. W. Penny, A. Pontin, P. F. Barker
Cooling the centre-of-mass motion is an important tool for levitated optomechanical systems, but it is often not clear which method can practically reach lower temperatures for a p…
An ultra-narrow line width levitated nano-oscillator for testing dissipative wavefunction collapse
A. Pontin, N. P. Bullier, M. Toroš +1
Levitated nano-oscillators are seen as promising platforms for testing fundamental physics and testing quantum mechanics in a new high mass regime. Levitation allows extreme isolat…
Testing collapse models with levitated nanoparticles: the detection challenge
A. Vinante, A. Pontin, M. Rashid +3
We consider a nanoparticle levitated in a Paul trap in ultrahigh cryogenic vacuum, and look for the conditions which allow for a stringent noninterferometric test of spontaneous co…
Imaging correlations in heterodyne-detected spectra for quantum sensing
A. Pontin, J. E. Lang, A. Chowdhury +6
The extraordinary sensitivity of the output field of an optical cavity to small quantum-scale displacements has led to breakthroughs such as the first detection of gravitational wa…
