Demonstration of the minimal coupling of horizontal accelerations to rotations in a torsion balance suspended from three wires
Amit Singh Ubhi, Clive C. Speake, Emilia Chick +1
The Cavendish torsion balance is the instrument of choice for measuring weak forces, such as gravity. Although torsion balances have extremely high sensitivity for measuring forces…
Design of electrostatic feedback for an experiment to measure
Stephan Schlamminger, Leon Chao, Vincent Lee +2
The torsion pendulum at the heart of the apparatus to measure the gravitational constant, at the Bureau International des Poids et Mesures (BIPM) is used to measure the gravita…
Galactic Dynamics in General Relativity: the Role of Gravitomagnetism
Matteo Luca Ruggiero, Antonello Ortolan, Clive C. Speake
It is a well known fact that, in the absence of Dark Matter, the observation of the rotation curves of galaxies cannot be explained in terms of Newtonian gravity. Rotation curves b…
A proposal for detection of absolute rotation using superconductors and large voltages
E. M. Forgan, C. M. Muirhead, A. I. M. Rae +1
We describe designs for practical detectors of absolute rotation, which rely on the creation of magnetic fields by charged objects that are rotating with respect to an inertial fra…
Search of spin-dependent fifth forces with precision magnetometry
N. Crescini, G. Carugno, P. Falferi +3
Spin-dependent fifth-forces are associated with particles beyond the standard model. In particular, light pseudo-scalar bosons mediate long-range forces, allowing mass to interact…
An Air Suspension to Demonstrate the Properties of Torsion Balances with Fibres of Zero Length
C. Gettings, C. C. Speake
We report on the design and characterisation of an air-bearing suspension that has been constructed to highlight the properties of torsion balances with fibres of zero length. A fl…
