SUMMARY:Decoherence, friction, and thermalization of quantum rigid rotors
DESCRIPTION:A nanoscale quantum rigid rotor moving and revolving in a thin gas
experiences random collisions with the surrounding gas atoms, which lead
to decoherence and eventually to thermalization of the body. Depending
on how its rotation rate compares to the mean duration of the scattering
processes, the collisions might either decohere superpositions of rigid
body orientations or of angular momentum states. I will present the
general Markovian theory of classical and quantum rotational friction,
diffusion, thermalization, and decoherence of arbitrarily shaped rigid
bodies [1,2] and compare the resulting decoherence rates to recent
experiments with nitrogen superrotors [3,4].
