Observation of interspecies Feshbach resonances in an ultracold 39K-133Cs mixture and refinement of interaction potentials. [PDF]

, 2016
We observe interspecies Feshbach resonances due to s-wave bound states in ultracold 39K -133Cs scattering for three different spin mixtures. The resonances are observed as joint atom loss and heating of the K sample.

Observation of bound state self-interaction in a nano-eV atom collider

Nature Communications, 2018
Self-interaction of a bound state through its coupling to the continuum is a phenomenon that is very difficult to observe. Here, the authors optically collide atomic clouds of rubidium and potassium to observe the self-interaction energy through precise ...

Feshbach engine in the Thomas-Fermi regime

Physical Review Research, 2020
Bose-Einstein condensates can be used to produce work by tuning the strength of the interparticle interactions with the help of Feshbach resonances. In inhomogeneous potentials, these interaction ramps change the volume of the trapped gas, allowing one ...

Experimental observation of the avoided crossing of two S-matrix resonance poles in an ultracold atom collider

Physical Review Research, 2021
In quantum mechanics, collisions between two particles are captured by a scattering matrix which describes the transfer from an initial entrance state to an outgoing final state.

Ultracold Three-Body Collisions near Overlapping Feshbach Resonances [PDF]

Physical Review Letters, 2009
We present a comprehensive collection of ultracold three-body collisions properties near overlapping Feshbach resonances. Our results incorporate variations of all scattering lengths and demonstrate novel collisional behavior, such as atom-molecule interference effects.

Anisotropy induced Feshbach resonances in mixture of

New Journal of Physics, 2015
We theoretically explore the scattering properties in collisions between ${}^{6}{\rm{Li}}$ in the ground state and fermionic ${}^{171}{\rm{Yb}}$ in the metastable ${}^{3}{{\rm{P}}}_{2}$ state.
