Exploring Quantum Magnetism (3 of 4)

Caption

This is an illustration of ultracold fermionic atoms in an optical lattice potential. Along the strong bonds of the lattice, antiferromagnetic (or anti-aligning) correlations form, detection of which has only now been achieved, allowing for a better understanding of the signature of quantum magnetism. This image relates to a paper that appeared in the May 23, 2013, issue of Science Express, published by AAAS. The paper, by Daniel Greif at ETH Zurich in Zurich, Switzerland, and colleagues, was titled, "Short-Range Quantum Magnetism of Ultracold Fermions in an Optical Lattice."
