Full-dimensional quantum dynamics of ultracold Li-CaH collisions in a magnetic field

We present a theoretical study of ultracold Li-CaH collisions in a magnetic field using a full-dimensional potential energy surface with an explicit dependence on the CaH vibrational coordinate. Elastic and inelastic cross sections will be presented as a function of magnetic field and implications will be discussed for sympathetic cooling of $^2\Sigma$ molecular radicals with ultracold alkali-metal atoms in a magnetic trap.
