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…
Characterisation of a charged particle levitated nano-oscillator
N. P. Bullier, A. Pontin, P. F. Barker
We describe the construction and characterisation of a nano-oscillator formed by a Paul trap. The frequency and temperature stability of the nano-oscillator was measured over sever…
Super-resolution imaging of a low frequency levitated oscillator
N. P. Bullier, A. Pontin, P. F. Barker
We describe the measurement of the secular motion of a levitated nanoparticle in a Paul trap with a CMOS camera. This simple method enables us to reach signal-to-noise ratios as go…
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…
