WebDec 15, 2024 · Resolving Feshbach resonances down to a full-width at half-maximum (FWHM) of 0.4(1) G, we can estimate an upper bound for the collision energy E col in the two-body centre-of-mass frame. WebDec 6, 2024 · Download PDF Abstract: Feshbach resonances are fundamental to interparticle interactions and become particularly important in cold collisions with atoms, ions, and molecules. Here we present the detection of Feshbach resonances in a benchmark system for strongly interacting and highly anisotropic collisions -- molecular …
Feshbach Resonances in Ultracold Gases - Göteborgs …
Web1 day ago · The presence of Feshbach resonances has been shown to have marked consequences in the determination of photoionization phases in the context of RABBIT and streaking experiments performed in the N 2 and H 2 molecules (22, 34, 35), where not only the energy (and eventually the ejection direction) of the electron must be measured (as … WebExperimental determination of Feshbach resonances in the 1,1 state of 39K: (a) remaining atom number; (b) sample temperature. The hold time for the low field (high field) resonance was 480ms (36ms). The curves are phenomenological fits with Gaussian distributions. where a bg is the background scattering length, is the resonance width, … hudsonnews st1181

WebFeshbach resonance at a finite energy by Genkina et al. by splitting a trapped cloud of 40K into two momentum components28. In this study, we report on the use of an optical collider29, 30 based on steerable optical tweezers to explore the E and B-dependent scattering of 87Rb atoms for a Feshbach resonance. WebFeshbach Resonance In Action by Martin Zwierlein (PhD ’06) Feshbach resonances are a unique tool for the study of ultracold atoms. By the simple change of a magnetic field, the … WebFeshbach resonance is a resonance for two-atom scattering with two or more channels, in which a bound state is achieved in one channel. We show that this resonance … hudsonnews st708
