Ultra-stable cryogenic optical resonators for tests of fundamental physics
M. Nagel, K. Möhle, K. Döringshoff +3
We present the design and first measurement results for an ultra-stable cryogenically cooled optical sapphire resonator system with a potential relative frequency stability better…
Electromagnetic cavity tests of Lorentz invariance on Earth and in space
M. Nagel, K. Möhle, K. Döringshoff +2
We present a Michelson-Morley type experiment for testing the isotropy of the speed of light in vacuum and matter. The experiment compares the resonance frequency of an actively ro…
Towards an ultra-stable optical sapphire cavity system for testing Lorentz invariance
M. Nagel, A. Peters
We present a design for an ultra-stable cryogenically cooled sapphire optical cavity system, with fractional frequency stability better than 1 x 10^-16 at one second integration ti…
Testing Lorentz Invariance by Comparing Light Propagation in Vacuum and Matter
M. Nagel, K. Möhle, K. Döringshoff +4
We present a Michelson-Morley type experiment for testing the isotropy of the speed of light in vacuum and matter. The experiment compares the resonance frequency of a monolithic o…
Rotating optical cavity experiment testing Lorentz invariance at the 10^{-17} level
S. Herrmann, A. Senger, K. Möhle +3
We present an improved laboratory test of Lorentz invariance in electrodynamics by testing the isotropy of the speed of light. Our measurement compares the resonance frequencies of…
