Quantum defect theory description of weakly bound levels and Feshbach resonances in LiRb

New Journal of Physics, 2015
The multichannel quantum defect theory (MQDT) in combination with the frame transformation (FT) approach is applied to model the Fano–Feshbach resonances measured for ^7 Li ^87 Rb and ^6 Li ^87 Rb Marzok et al (2009 Phys. Rev. A http://dx.doi.org/10.1103/

Nonlinear Fano-Feshbach resonances

, 2016
We study the wave scattering in an one-dimensional discrete system with two side-coupled defects. Each of the defects exhibits the Fano resonance as a resonant suppression of transmission, i.e., resonant reflection.

40K-87Rb Feshbach resonances: Modeling the interatomic potential [PDF]

, 2007
We have observed 28 heteronuclear Feshbach resonances in ten spin combinations of the hyperfine ground states of a 40K−87Rb mixture. The measurements were performed by observing the loss rates from an atomic mixture at magnetic fields between 0 and 700G.

Theory of dissociative electron attachment: Biomolecules and clusters

EPJ Web of Conferences, 2015
Very broad σ∗ resonances, which are responsible for threshold structures and dissociative attachment in electron collisions with hydrogen halides, are also important in electron-impact bond-breaking in nucleobases and amino acids.

P-wave Feshbach resonances of ultra-cold $^6$Li

, 2004
4 pages, 5 figures, accepted by PRAWe report the observation of three p-wave Feshbach resonances of $^6$Li atoms in the lowest hyperfine state $f=1/2$. The positions of the resonances are in good agreement with theory.

Universal coherent atom-molecule oscillations in the dynamics of the unitary Bose gas near a narrow Feshbach resonance

Physical Review Research
Quench experiments on a unitary Bose gas around a broad Feshbach resonance have led to the discovery of universal dynamics. This universality manifests in the measured atomic momentum distributions, where, asymptotically, a quasiequilibrated metastable ...

Multichannel Quantum Defect Theory with Numerical Reference Functions: Applications to Cold Atomic Collisions

Atoms
We develop a method for calculating multichannel wavefunctions in the spirit of quantum defect theory, based on numerically calculated reference functions. We benchmark the method by calculating cold collisional properties of 85Rb and 6Li in the presence

Observation of high partial-wave Feshbach resonances in 39K Bose–Einstein condensates

New Journal of Physics
We report the new observation of several high partial-wave (HPW) magnetic Feshbach resonances (FRs) in ^39 K atoms of the hyperfine substate $\left|F = 1,m_{F} = -1\right\rangle$ .
