Thermometry and Refrigeration in a Two-Component Mott Insulator of Ultracold Atoms

In this work [1], we describe and analyze theoretically the two techniques of spin-gradient thermometry and spin gradient demagnetization cooling developed earlier by our group [2, 3].

A Magnetic Gas

For decades, it has been an open question whether it is possible for a gas to show properties similar to a magnet made of iron or nickel.  Iron and nickel are ferromagnetic because they become strongly magnetized below a specific temperature, when unpaired electrons within the material spontaneously align in the same direction.

When one electron is not enough ….

Most research involving ultra-cold matter has been done with atoms with one active electron (i.e. an electron outside a closed shell of electrons).  New theoretical work by CUA researchers has demonstrated that atoms with two active electrons (the so called alkaline-earth atoms)
