Reactive collisions in confined geometries
Zbigniew Idziaszek, Krzysztof Jachymski, Paul S. Julienne
We consider low energy threshold reactive collisions of particles interacting via a van der Waals potential at long range in the presence of external confinement and give analytic…
Observation of orbiting resonances in He(3S1) + NH3 Penning ionization
Justin Jankunas, Krzysztof Jachymski, Michal Hapka +1
Resonances are among the clearest quantum mechanical signatures of scattering processes. Previously, shape resonances and Feshbach resonances have been observed in inelastic and re…
Quantum defect model of a reactive collision at finite temperature
Krzysztof Jachymski, Michał Krych, Paul S. Julienne +1
We consider a general problem of inelastic collision of particles interacting with power-law potentials. Using quantum defect theory we derive an analytical formula for the energy-…
Dynamics of gas phase Ne + NH and Ne + ND Penning ionization at low temperatures
Justin Jankunas, Benjamin Bertsche, Krzysztof Jachymski +2
Two isotopic chemical reactions, + NH, and + ND, have been studied at low collision energies by means of a merged beams technique. Partial c…
Fast quantum gate via Feshbach-Pauli blocking in a nanoplasmonic trap
Krzysztof Jachymski, Zbigniew Idziaszek, Tommaso Calarco
We propose a simple idea for realizing a quantum gate with two identical fermions in a double well trap via external optical pulses without addressing the atoms individually. The k…
