Experimental Progress in a Cryogenic Cold Atom Quantum Materials Sensor

POSTER

Abstract

Cold atoms are a versatile diagnostic tool for quantum materials due to its high electric and magnetic fields sensitivity. We present updates on our novel sensing platform that leverages these sensing capabilities to characterize quantum materials in a cryogenic environment. The installed system is fitted with MOT making optics internally and externally, including a set of superconducting coils. A 2D MOT is created at one of the chamber arms at 10-7 Torr and is demonstrated to be recoverable after a complete vacuum chamber opening and closing procedure. This is a first step towards generating a 3D MOT in the main chamber.
