Universality and threshold laws for collision lifetimes at ultralow temperatures
Rebekah Hermsmeier, Timur V. Tscherbul
While collision lifetimes are a fundamental property of few-body scattering events, their behavior at ultralow temperatures is not completely understood. We derive a general expres…

Highly spin-polarized molecules via collisional microwave pumping
Rebekah Hermsmeier, Timur V. Tscherbul
We propose a general technique to produce cold spin-polarized molecules, in which rotationally excited states are first populated by coherent microwave excitation, and then allowed…

Quantum spin state selectivity and magnetic tuning of ultracold chemical reactions of triplet alkali-metal dimers with alkali-metal atoms
Rebekah Hermsmeier, Jacek Klos, Svetlana Kotochigova +1
We demonstrate that it is possible to efficiently control ultracold chemical reactions of alkali-metal atoms colliding with open-shell alkali-metal dimers in their metastable tripl…
