Thermometry and Refrigeration in a Two-Component Mott Insulator of Ultracold Atoms
David M. Weld, Hirokazu Miyake, Patrick Medley +2
Interesting spin Hamiltonians can be realized with ultracold atoms in a two-component Mott insulator (2CMI). It was recently demonstrated that the application of a magnetic field g…
Spin gradient demagnetization cooling of ultracold atoms
Patrick Medley, David M. Weld, Hirokazu Miyake +2
A major goal of ultracold atomic physics is quantum simulation of spin Hamiltonians in optical lattices. Progress towards this goal requires the attainment of extremely low tempera…
Spin gradient thermometry for ultracold atoms in optical lattices
David M. Weld, Patrick Medley, Hirokazu Miyake +3
We demonstrate spin gradient thermometry, a new general method of measuring the temperature of ultracold atoms in optical lattices. We realize a mixture of spins separated by a mag…
Phase diagram for a Bose-Einstein condensate moving in an optical lattice
Jongchul Mun, Patrick Medley, Gretchen K. Campbell +3
The stability of superfluid currents in a system of ultracold bosons was studied using a moving optical lattice. Superfluid currents in a very weak lattice become unstable when the…
Atom trapping with a thin magnetic film
Micah Boyd, Erik W. Streed, Patrick Medley +4
We have created a Rb Bose-Einstein condensate in a magnetic trapping potential produced by a hard disk platter written with a periodic pattern. Cold atoms were loaded from a…
Imaging the Mott Insulator Shells using Atomic Clock Shifts
Gretchen K. Campbell, Jongchul Mun, Micah Boyd +5
Microwave spectroscopy was used to probe the superfluid-Mott Insulator transition of a Bose-Einstein condensate in a 3D optical lattice. Using density dependent transition frequenc…
