Measurement of the motional heating of a levitated nanoparticle by thermal light
A. T. M. Anishur Rahman, P. F. Barker
We report on measurements of photon induced heating of silica nanospheres levitated in vacuum by a thermal light source formed by a superluminescent diode. Heating of the nanospher…
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…
A Spin Entanglement Witness for Quantum Gravity
Sougato Bose, Anupam Mazumdar, Gavin W. Morley +7
Understanding gravity in the framework of quantum mechanics is one of the great challenges in modern physics. Along this line, a prime question is to find whether gravity is a quan…
