Are you familiar with this,?,,

"Writing about the work in the scientific journal Nature, the researchers describe how they discovered that at high magnetic fields (above 23 Tesla) and at temperatures between 1 and 3 degrees Kelvin (or roughly minus 460 degrees Fahrenheit), the magnetic waves in Han purple crystals "exist" in a unique state of matter called a Bose Einstein condensate (BEC). In the BEC state, magnetic waves propagate simultaneously in all of three directions (up-down, forward-backward and left-right). At the quantum critical point, however, the waves stop propagating in the up-down dimension, causing the magnetic ripples to exist in only two dimensions, much the same way as ripples are confined to the surface of a pond".

"The reduced dimensionality really came as a surprise," said Neil Harrison, an experimental physicist at the Los Alamos Pulsed Field Facility, "just when we thought we had reached an understanding of the quantum nature of its magnetic BEC."
