Dysprosium Quantum Gases

Dysprosium Quantum Gases

Advances in the quantum manipulation of ultracold atomic gases are opening a new frontier in the quest to better understand strongly correlated matter.  By exploiting the long-range and anisotropic character of the dipole-dipole interaction, we hope to create novel forms of soft quantum matter, phases intermediate between canonical states of order and disorder.  Our group recently created Bose and Fermi degenerate gases of the most magnetic atom, dysprosium, which should allow investigations of quantum liquid crystals, analogs to the electron nematics and smectics thought to exist in, e.g., high-Tc cuprate superconductors.
