Microscopic magnetic-field imaging

Article Abstract:

One-dimensional Bose-Einstein condensates (BEC) are used in a microscopic field-imaging technique that combines high spatial resolution with high sensitivity. A comparison of different magnetic-field measurement techniques shows that BECs as magnetic sensors could reach unprecedented sensitivity over a large range of spatial resolution.

Berezinskii-Kosterlitz-Thoiless crossover in a trapped atomic gas

Article Abstract:

The observation of a Berezinskii-Kosterlitz-Thoiless (BKT)-type crossover in a trapped quantum degenerate gas of rubidium atoms is reported. The findings provide direct experimental evidence for the microscopic mechanism underlying the BKT theory, and raise new queries regarding coherence and superfluidity in mesoscopic systems.
