Strengthening constraints on Yukawa-type corrections to Newtonian gravity from measuring the Casimir force between a cylinder and a plate
Newtonian gravity Casimir force cylinder plate
2010/12/20
We discuss possibility to obtain stronger constraints on non-Newtonian gravity from measuring
the gradient of the Casimir force between a cylinder and a plate. Exact analytical expression
for the Yu...

2010/10/20
We show how entanglement may be quantified in spin and cold atom many-body systems using standard experimental techniques only. The scheme requires no assumptions on the state in the laboratory and a ...
A geometric invariant measuring the deviation from Kerr data
geometric invariant Kerr data
2010/3/18
A geometrical invariant for regular asymptotically Euclidean data for the vacuum Einstein field equations is constructed. This invariant vanishes if and only if the data corresponds to a slice of the ...
Measuring the quality of a quantum reference frame: the relative entropy of frameness

In the absence of a reference frame for transformations associated with a group G, any quantum state that is non-invariant under the action of G may serve as a token of the missing reference frame. We...
