Bringing multilevel quantum master equations into Lindblad form for complete positivity tests: Two approaches
Timur V. Tscherbul
While quantum master equations (QMEs) are the primary workhorse in quantum information science, quantum optics, spectroscopy, and quantum thermodynamics, bringing an arbitrary -…
Population Oscillations and Ubiquitous Coherences in multilevel quantum systems driven by incoherent radiation
Amro Dodin, Timur V. Tscherbul, Paul Brumer
We consider incoherent excitation of multilevel quantum systems, e.g. molecules with multiple vibronic states. We show that (1) the geometric constraints of the matter-field coupli…
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…
Sympathetic cooling and slowing of molecules with Rydberg atoms
Chi Zhang, Seth T. Rittenhouse, Timur V. Tscherbul +2
We propose to sympathetically slow and cool polar molecules in a cold, low-density beam using laser-cooled Rydberg atoms. The elastic collision cross sections between molecules and…
Robust Coherent Control of Bimolecular Collisions beyond the Ultracold Regime
Adrien Devolder, Paul Brumer, Timur Tscherbul
Quantum coherent control of bimolecular collisions beyond the ultracold regime can face a major challenge due to the incoherent addition of different partial wave contributions to…
Ultracold molecular collisions in magnetic fields: Efficient incorporation of hyperfine structure in the total rotational angular momentum representation
Timur V. Tscherbul, Jose P. D'Incao
The effects of hyperfine structure on ultracold molecular collisions in external fields are largely unexplored due to major computational challenges associated with rapidly prolife…
