Identical-Particle Symmetry-Enabled Complete Coherent Control of Ultracold Atomic and Molecular Collisions
Jing-Chen Zhang, Adrien Devolder, Timur V. Tscherbul +2
We show that exchange symmetry in collisions of identical particles enables symmetry-protected coherent control of the total scattering cross section. For identical fermions, antis…

Rotational decoherence dynamics in ultracold molecules induced by a tunable spin environment: The Central Rotor Model
Timur V. Tscherbul, Lincoln D. Carr
We show that quantum rotational wavepacket dynamics in molecules can be described by a new system-environment model, which consists of a rotational subsystem coupled to a magnetica…

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…
