Solving Problems in Atomic Superfluid Rotation Using Cavity Optomechanics
Abstract
This theoretical proposal aims to solve three outstanding problems in atomic superfluid rotation using the versatile tools of cavity optomechanics. Degenerate atomic gases in ring traps are currently under intense focus in the context of fundamental problems such as high temperature superconductivity, superfluid hydrodynamics, and early universe cosmology; and applications such as atomtronics and precision measurements. These systems currently face three outstanding problems- there is no protocol for using them as quantum memories although they can provide much larger storage times than currently available; fundamental effects like superfluid drag have been predicted but never observed; and no amplifier for rotating matter waves is available for detecting weak signals and fragile quantum states. This proposal will adapt existing tools from cavity optomechanics for information storage and retrieval, rotation detection, and coherent amplification to solve the above problems. Cavity optomechanics is a powerful paradigm for the measurement and manipulation of mechanical motion, with the detection of gravitational waves as a famous example. Standard theoretical methods of quantum optics will be used to produce relevant theoretical protocols and models for each problem. The proposal will fundamentally impact superfluid science by showing how to detect the basic effect of drag; quantum information science by designing a substantially improved memory; and quantum metrology by proposing an amplifier for matter waves - a new tool for quantum optics.
