A rigorous adiabatic approach to ultracold atom-molecule collisions in a magnetic field
Nathan S. Prins, Timur V. Tscherbul
We extend the rigorous adiabatic coupled-channel formalism to ultracold nonreactive atom-molecule collisions in the presence of an external magnetic field. The wavefunction of the…

Rigorous quantum calculations for atom-molecule chemical reactions in electric fields: from single to multiple partial wave regimes
Timur V. Tscherbul, Roman V. Krems
We present an efficient method for rigorous quantum calculations of cross sections for atom-molecule reactive scattering in the presence of a dc electric field. The wavefunction of…
