In 2009, Markus Greiner demonstrated a quantum gas microscope, where each site of the optical lattice can be resolved. For the first time, researchers could directly image the physical patterns that emerge in the atom arrangement as they interact within the lattice. Currently, there are nearly a dozen such quantum gas microscopes studying Rubidium, Lithium, Potassium, and Ytterbium.
“The behavior of ultracold atoms in optical lattices is similar to that of electrons in solids. Because of that, ultracold atoms can provide clean realizations of models from condensed matter which can be studied in a highly controlled environment.”

Susannah Dickerson of Greiner Lab, Harvard University said, “The goal of the new apparatus is to extend this previous work to the element Erbium, which is highly magnetic and quite sensitive to magnetic fields. So our vacuum chamber is to be produced from extremely low permeability 316LN stainless steel. With such low permeability, the material will experience very little hysteresis, leading to a stable magnetic field.”
Applied Vacuum is producing the critical vacuum system components using 316LN ESR material for all flanges and housings, and 316L for port tubes. The welded assemblies will be vacuum heat-treated to remove magnetism which results from machining and welding. The goal being to have the lowest possible magnetic permeability for the completed vacuum chamber.
Applied Vacuum Technology offers more than 25 years of experience fabricating custom chambers and related products for high and ultra-high vacuum applications. We provide a wide range of products, from large chambers and baseplates to small flanges and precise components. We also provide Engineering consultation for design and manufacturability. Our design and manufacturing resources will help take your requirements from initial concepts, to fully engineered designs, to completed and tested products ready for use.
