Feshbach共振磁场

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. WebFirst described by Herman Feshbach in a 1958 paper, Feshbach resonances describe resonant scattering between two particles when their incoming energies are very close to those of a two-particle bound state. Feshbach resonances were rst applied to tune the interactions between ultracold Fermi gases in the late 1990’s.

In physics, a Feshbach resonance can occur upon collision of two slow atoms, when they temporarily stick together forming an unstable compound with short lifetime (so-called resonance). It is a feature of many-body systems in which a bound state is achieved if the coupling(s) between at least one internal degree of freedom and the reaction coordinates, which lead to dissociation, vanish. The opposite situation, when a bound state is not formed, is a shape resonance. It is na… WebThe Feshbach coils provide up to 1000G magnetic offset field, while the fast coil generates an extra 36G for a arXiv:2103.05273v1 [cond-mat.quant-gas] 9 Mar 2024 fried pork chops and gravy recipes skillet https://elyondigital.com

WebThe Fano resonance and the Feshbach resonance are the same thing, when it comes to their mathematical essence. Both of them describe the resonances with the asymmetric shapes and were derived during some research of the coupling between the bound states and continuum.
