First Images Of Landau Levels

Ok, I didn't realize that we haven't had a measurement of such landau levels till now. It appears that this has finally been imaged.

Using scanning tunnelling spectroscopy - a spatially resolved probe that interacts directly with the electrons - scientists at institutions including the University of Warwick and Tohoku University have revealed the internal ring-like structure of these Landau Levels at the surface of a semiconductor.

What is also interesting that this could tie in to the standard definition of a kilogram.
