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…
General framework for quantifying entanglement production in ultracold molecular collisions and chemical reactions
Adrien Devolder, Paul Brumer, Timur Tscherbul
Entanglement, a defining feature of quantum mechanics, arises naturally from interactions between molecular systems. Yet the precise nature and quantification of entanglement in th…
Leveraging Reactant Entanglement in the Coherent Control of Ultracold Bimolecular Chemical Reactions
Adrien Devolder, Timur Tscherbul, Paul Brumer
Entanglement is a crucial resource for achieving quantum advantages in quantum computation, quantum sensing, and quantum communication. As shown in this Letter, entanglement is als…
Time-Reversal Symmetry-Protected Coherent Control of Ultracold Molecular Collisions
Adrien Devolder, Timur V. Tscherbul, Paul Brumer
Coherent control of atomic and molecular scattering relies on the preparation of colliding particles in superpositions of internal states, establishing interfering pathways that ca…
Magnetic Feshbach resonances in ultracold atom-molecule collisions
Masato Morita, Maciej B. Kosicki, Piotr S. Zuchowski +2
We report numerically exact quantum scattering calculations on magnetic Feshbach resonances in ultracold, strongly anisotropic atom-molecule [Rb(S) + SrF()] collisions b…
Interference is in the eye of the beholder: application to the coherent control of collisional processes
Adrien Devolder, Timur V. Tscherbul, Paul Brumer
Interference is widely regarded as a foundational attribute of quantum mechanics. However, for a given experimental arrangement, interference can either contribute or not contribut…
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…
Coherent Control of ultracold molecular collisions: The role of resonances
Adrien Devolder, Timur V. Tscherbul, Paul Brumer
We consider the coherent control of ultracold molecule-molecule scattering, impacted by a dense set of rovibrational resonances. To characterize the resonance spectrum, a rudimenta…
Signatures of Non-universal Quantum Dynamics of Ultracold Chemical Reactions of Polar Alkali-dimer Molecules with Alkali-metal Atoms: Li(S) +NaLi() Na(S) + Li()
Masato Morita, Brian K. Kendrick, Jacek Kłos +3
Ultracold chemical reactions of weakly bound triplet-state alkali-metal dimer molecules have recently attracted much experimental interest. We perform rigorous quantum scattering c…
Near-threshold scaling of resonant inelastic collisions at ultralow temperatures
Rebekah Hermsmeier, Adrien Devolder, Paul Brumer +1
We show that the cross sections for a broad range of resonant {\it inelastic} processes accompanied by excitation exchange (such as spin-exchange, Förster resonant, or angular mome…
Complete quantum coherent control of ultracold molecular collisions
Adrien Devolder, Paul Brumer, Timur V. Tscherbul
We show that quantum interference-based coherent control is a highly efficient tool for tuning ultracold molecular collision dynamics, and is free from the limitations of commonly…
Spin-orbit interactions and quantum spin dynamics in cold ion-atom collisions
Timur V. Tscherbul, Paul Brumer, Alexei A. Buchachenko
We present accurate ab initio and quantum scattering calculations on a prototypical hybrid ion-atom system Yb-Rb, recently suggested as a promising candidate for the experiment…
Coherent dynamics of Rydberg atoms in cosmic microwave background radiation
Timur V. Tscherbul, Paul Brumer
Rydberg atoms excited by cold blackbody radiation are shown to display long-lived quantum coherences on timescales of tens of picoseconds. By solving non-Markovian equations of mot…
