Status of a modern Michelson Morley experiment using ultrastable cryogenic cavities and shot noise limited cryogenic detectors — •Erich Günter Leo Pape, Evgeny Kovalchuk, and Achim Peters — Newtonstr. 15, 12489, Berlin, Humboldt Universität zu Berlin, Institut für Physik
We present advancements in cryogenic experiments, showcasing an optical sapphire cavity setup for a Michelson-Morley experiment on Lorentz violations with a target frequency stability of 10−16 Hz/√Hz. Furthermore, we present our cryogenic detectors using a cryogenic MESFET preamplifier for high bandwidth shot noise-limited performance at 10µ W laser power, contributing to enhanced precision in signal detection.
