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…
Magnetically tunable electric dipolar interactions of ultracold polar molecules in the quantum ergodic regime
Rebekah Hermsmeier, Ana Maria Rey, Timur V. Tscherbul
By leveraging the hyperfine interaction between the rotational and nuclear spin degrees of freedom, we demonstrate extensive magnetic control over the electric dipole moments, elec…
Nuclear spin relaxation in cold atom-molecule collisions
Rebekah Hermsmeier, Xiaodong Xing, Timur V. Tscherbul
We explore the quantum dynamics of nuclear spin relaxation in cold collisions of molecules with structureless atoms in an external magnetic field. To this end, we develop a…
Total angular momentum representation for state-to-state quantum scattering of cold molecules in a magnetic field
Suyesh Koyu, Rebekah Hermsmeier, Timur V. Tscherbul
We show that the integral cross sections for state-to-state quantum scattering of cold molecules in a magnetic field can be efficiently computed using the total angular momentum re…
Near-threshold scaling of resonant inelastic collisions at ultralow temperatures
Rebekah Hermsmeier, Adrien Devolder, Paul Brumer +1
We show that the cross sections for a broad range of resonant {\it inelastic} processes accompanied by excitation exchange (such as spin-exchange, Förster resonant, or angular mome…
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…
Ion Modes in Dense Ionized Plasmas through Non-Adiabatic Molecular Dynamics
Ryan A. Davis, W. A. Angermeier, R. Hermsmeier +1
We perform nonadiabatic simulations of warm dense aluminum based on the electron-force field (EFF) variant of wave-packet molecular dynamics. Comparison of the static ion-ion struc…
