Spatial resolution of spin waves in an ultra-cold gas

TL;DR

This paper reports the first spatially resolved imaging of spin waves in an ultra-cold gas, reconstructing the full spin field over time and space, and analyzing their frequencies and damping rates.

Contribution

It provides the first detailed spatial and temporal imaging of spin waves in an ultra-cold gas, enabling direct comparison with theoretical models.

Findings

Reconstructed the complete spin field in space and time.

Measured frequencies and damping rates of standing-wave modes.

Compared experimental results with theoretical predictions.

Abstract

We present the first spatially resolved images of spin waves in a gas. The complete longitudinal and transverse spin field as a function of time and space is reconstructed. Frequencies and damping rates for a standing-wave mode are extracted and compared with theory.
