Test of the equivalence principle using a rotating torsion balance.
We used a continuously rotating torsion balance instrument to measure the acceleration difference of beryllium and titanium test bodies towards sources at a variety of distances. Our result Deltaa(N),(Be-Ti)=(0.6+/-3.1)x10(-15) m/s2 improves limits on equivalence-principle violations with ranges from 1 m to infinity by an order of magnitude. The Eötvös parameter is eta(Earth,Be-Ti)=(0.3+/-1.8)x...
متن کاملMetric fluctuations and the Weak Equivalence Principle
We describe space–time fluctuations by means of small fluctuations of the metric on a given background metric. From a minimally coupled Klein–Gordon equation we obtain within a weakfield approximation up to second order and an averaging procedure over a finite space–time scale given by the quantum particle in the non–relativistic limit a modified Schrödinger equation. The dominant modification ...
متن کاملEquivalence Principle parity violation tests
Gravitation is parity symmetric or antisymmetric. Mass distribution parity divergence varies from χ = 0 (achiral) to χ = 1 (perfect). A parity Eötvös experiment contrasts chemically and macroscopically identical enantiomorphic space groups P3121 and P3221 α-quartz single crystal test masses. A parity calorimetry experiment contrasts P3121 and P3221 benzil single crystals enthalpies of fusion. ...

15 صفحه اولProspects for terrestrial equivalence principle tests with a cryogenic torsion pendulum
A torsion pendulum may be used to measure effective differential accelerations of test masses in the field of sources on distance scales below those accessible in a space experiment such as STEP. Operation of a torsion pendulum at low temperature (2 K) offers many benefits, notably: low thermal noise, high fibre stability, highly effective superconducting magnetic shielding and excellent temper...
