We present an experimental procedure, based on Meissner effect levitation of neodymium ferromagnets, as a method of measuring the gravitational interactions between mg masses. The scheme consists of two superconducting lead traps, with a magnet levitating in each trap. The levitating magnets behave as harmonic oscillators, and by carefully driving the motion of one magnet on resonance with the other, we find that it should be easily possible to measure the gravitational field produced by a 4 mg…

Acceleration sensing with magnetically levitated oscillators above a superconductor

We experimentally demonstrate the stable trapping of a permanent magnet sphere above a lead superconductor, at vacuum pressures of 4 × 10 − 8 mbar. The levitating magnet behaves as a harmonic…

Measurement of gravitational coupling between millimetre-sized masses.

Gravity coupling between two gold spheres of 1 millimetre radius is shown, thereby entering the regime of sub-100-milligram sources of gravity and opening the way to the unexplored frontier of microscopic source masses, which will enable studies of fundamental interactions and provide a path towards exploring the quantum nature of gravity.

Characterisation of a charged particle levitated nano-oscillator

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 several days allowing us…

Testing the gravitational field generated by a quantum superposition

What gravitational field is generated by a massive quantum system in a spatial superposition? Despite decades of intensive theoretical and experimental research, we still do not know the answer. On…

On the Gravitization of Quantum Mechanics 1: Quantum State Reduction

This paper argues that the case for “gravitizing” quantum theory is at least as strong as that for quantizing gravity. Accordingly, the principles of general relativity must influence, and actually…

Measurement of the Instantaneous Velocity of a Brownian Particle

A single, optically trapped silica bead is used to probe the dynamics of Brownian motion, measuring the predicted instantaneous velocity of the particle and verifying the short-time-scale behavior predicted a century ago, providing direct verification of the energy equipartition theorem for a Brownian particle.

Quantum test of the equivalence principle for atoms in coherent superposition of internal energy states

A novel WEP test for atoms is reported: a Bragg atom interferometer in a gravity gradiometer configuration compares the free fall of rubidium atoms prepared in two hyperfine states and in their coherent superposition, using the use of the superposition state.
