Microscopic magnetometry with degenerate 1D Bose gases
Abstract/Contents
- Abstract
- This thesis presents a novel scanning probe magnetometer suitable for cryogenic studies, in which the probe is a degenerate 1D Bose gas of 87-Rb. The system is designed for rapid sample changes and operation between 35 K (with possible extension to 5 K) and room temperature while remaining compatible with the UHV requirements of ultracold atom experiments. Using a sample with microscopic fabricated current paths, we demonstrate a spatial resolution (2 [sigma]) of 2.2 ± 0.2 [mu] m and a repeatability of 1.9 ± 1.0 nT, with uncertainties as low as 100 pT attainable with repeated measurements. By separately investigating various noise sources, we show that the system is operating close to the fundamental measurement limits set by photon shot noise and atom shot noise. This scanning quantum cryogenic atom microscope is suitable for fundamental studies of transport and magnetism in condensed matter systems such as high-temperature superconductors and topological insulators.
