Limit on Lorentz and CPT Violation of the Proton Using a Hydrogen Maser
D. F. Phillips, M. A. Humphrey, E. M. Mattison +3
We present a new measurement constraining Lorentz and CPT violation of the proton using a hydrogen maser double resonance technique. A search for hydrogen Zeeman frequency variatio…
Measurement of the 21Ne Zeeman frequency shift due to Rb-21Ne collisions
R. E. Stoner, R. L. Walsworth
We compared the frequency shift of the 21Ne Zeeman resonance induced by polarized Rb vapor to the shift induced in the 3He Zeeman resonance. The 3He/Rb shift has recently been meas…
New Clock Comparison Searches for Lorentz and CPT Violation
Ronald L. Walsworth, David Bear, Marc Humphrey +4
We present two new measurements constraining Lorentz and CPT violation using the Xe-129 / He-3 Zeeman maser and atomic hydrogen masers. Experimental investigations of Lorentz and C…
