Magnetic field dependent interactions in an ultracold Li–Yb(3P2) mixture
New Journal of Physics, 2015 Magnetic Feshbach resonances have allowed great success in the production of ultracold diatomic molecules from bi-alkali mixtures, but have so far eluded observation in mixtures of alkali and alkaline-earth-like atoms. Inelastic collisional properties of

An efficient nonlinear Feshbach engine
New Journal of Physics, 2018 We investigate a thermodynamic cycle using a Bose–Einstein condensate (BEC) with nonlinear interactions as the working medium. Exploiting Feshbach resonances to change the interaction strength of the BEC allows us to produce work by expanding and ...

Feshbach resonances in ultracold atom-diatom scattering
, 2019 Quantum-mechanical scattering calculations of Feshbach resonances arising from van der Waals molecule formation are used to determine vibrational and rotational predissociation lifetimes.

Physics Letters B, 2016 We propose a new interpretation of the neutral and charged X,Z exotic hadron resonances. Hybridized-tetraquarks are neither purely compact tetraquark states nor bound or loosely bound molecules but rather a manifestation of the interplay between the two.

Feshbach spectroscopy of an ultracold Rb-Cs mixture [PDF]
, 2012 This thesis reports the observation of interspecies Feshbach resonances in an ultracold mixture of Rb and Cs atoms. A versatile combined magnetic and optical potential has been designed and constructed which is capable of bringing both $^{87}\rm{Rb}$ and

Magnetic control of ultra-cold 6Li and 174Yb(3P2) atom mixtures with Feshbach resonances
New Journal of Physics, 2015 We theoretically evaluate the feasibility to form magnetically-tunable Feshbach molecules in collisions between fermionic ^6 Li atoms and bosonic metastable ^174 Yb( ^3 P _2 ) atoms.

Political Psychology, Volume 47, Issue 2, April 2026.Abstract Whilst survey research on national attachments has used various measures, the question of how respondents understand these measures, and especially the highly ambiguous concepts they entail, has remained understudied. Moreover, scholars have used samples consisting of “citizens”, thereby not distinguishing between citizens with and citizens ...

Realisation of a cold mixture of rubidium and caesium [PDF]
, 2008 This thesis describes a new apparatus designed to study cold, ultracold, and quantum degenerate mixtures of rubidium and caesium atoms. The Rb- Cs mixture is prepared using a double magneto-optical trap (MOT) system in which a two-species pyramid MOT ...
