Development of Superfluid 4He Matter Wave Interferometers
Abstract
Approach:In order to make advances in 4He matter wave interferometry, we will focus on two importantdirections: develop a Josephson junction structure which can work well at 1.2 K (deep into the superfluid phase,) and improve the detection of the superfluid mass current to thermodynamic limits. The goal is to produce a system which can work at the thermodynamic limit for detection (thermal fluctuations of the superfluid) and maximize the sensitivity for detection of the quantum phase.Objective:The development of a system which could be ?fielded on a submarine, and produce a system which could be used as an Earth rotation observatory.Naval Relevance:We expect this work to make significant advances in the area of ultra-sensitive matter-wave interferometry, which will have applications and impact in ultra-sensitive inertial sensing, rotation measurement, navigation, GPS, geodesy, and as a precision tool to explore fundamental physics. We aim to create a system which could be ?fielded on a submarine, and produce a system which could be used as an Earth rotation observatory.
