2-D topological physics from shaking a 1-D wire
(PHYSorg.com Physics)

Limiting quantum particles to move in one, two, or three dimensions has led to the observation of many striking phenomena. A prime example is the quantization of the Hall conductance measured in 2-D materials in a strong magnetic field. Nowadays, gases of ultracold atoms provide a powerful platform for easily controlling the dimensionality of quantum systems. However, it is challenging in these setups to measure conductance properties, and a `cold-atomic quantum Hall effect` is yet to be observed.
