Cold Atom Based Gravity Sensor

Lead Research Organisation: University of Birmingham
Department Name: School of Physics and Astronomy

Abstract

The student will study atom interferometry with cold atoms. He will learn how to operate an exisiting instrument and design additions to the detection system. In particular he will learn about non-destructive detection techniques and install a system, which can read out the output states of the atom interferometer in a quantum non-demolition way. He will implement and characterise the detection system and analyse the improvements in sesitivity this system allows to achieve.

Description We have discovered new ways of using optical cavities to improve the performance of atom interferometers. We are investigating further and the work is still on going.
Exploitation Route These ideas may have applications in field based cold atom sensors, such as the gravity pioneer project. This has applications in civil engineering, and a broader range disucssed on the quantum sensing hub website. The wider field are working on navigation systems using atom interferometry, which may have wide ranging applications. There are some fundamental physics experiments that may take these techniques forward.
