Multichannel quantum defect theory with a frame transformation for ultracold atom-molecule collisions in magnetic fields
Masato Morita, Paul Brumer, Timur V. Tscherbul
We extend the powerful formalism of multichannel quantum defect theory combined with a frame transformation to ultracold atom-molecule collisions in magnetic fields. By solving the…
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…
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…
Coherent control of reactive scattering at low temperatures: Signatures of quantum interference in the differential cross sections for F + H2 and F + HD
Adrien Devolder, Timur Tscherbul, Paul Brumer
Fundamental entanglement related challenges have prevented quantum interference-based control (i.e. coherent control) of collisional cross sections from being implemented in the la…
Magnetic tuning of ultracold barrierless chemical reactions
Timur V. Tscherbul, Jacek Kłos
While attaining external field control of bimolecular chemical reactions has long been a coveted goal of physics and chemistry, the role of hyperfine interactions and dc magnetic f…
