Tunable state-dependent interactions in collisionally stable mixtures of polar molecules
Hubert J. Jóźwiak, Hanwei Yang, Eugen Dizer +2
We propose encoding a pseudo-spin- system in the ground () and first excited () vibrational states of polar molecules. Double microwave shielding simultaneously shie…
Ro-vibrational van der Waals interaction between ultracold polar molecules
Kang Feng, Hanwei Yang, Hubert J. Jóźwiak +1
We describe the ro-vibrational van der Waals interaction between ultracold polar molecules. This interaction is strong, leading to fast elastic collisions and orders of magnitude s…
A quadratic-scaling algorithm with guaranteed convergence for quantum coupled-channel calculations
Hubert J. Jóźwiak, Md Muktadir Rahman, Timur V. Tscherbul
Rigorous quantum dynamics calculations provide essential insights into complex scattering phenomena across atomic and molecular physics, chemical reaction dynamics, and astrochemis…
Mapping the parameter space of double microwave shielding
Hubert J. Jóźwiak, Hubert J. Jóźwiak, Ian Stevenson +2
Double microwave shielding employs - and -polarized microwave fields, tuned close to the lowest rotational transition, to engineer a long-range repulsive barrier between…
Full-dimensional quantum scattering calculations of rovibrationally excited HD+HD collisions
Bikramaditya Mandal, Hubert Jóźwiak, Piotr WcisÅo +1
Full-dimensional quantum scattering calculations are reported for ro-vibrational transitions in HD+HD collisions using a highly accurate interaction potential for the H-H s…
