Stabilization of three-body resonances to bound states in a continuum Open
Three-body resonances are ubiquitous in few-body physics and are characterized by a finite lifetime before decaying into continuum states of their composing subsystems. In this work we present a theoretical study on the possibility to stab…

Closed-channel parameters of Feshbach resonances Open
This work investigates how the closed channel of a Feshbach resonance is characterised by experimental observables. Surprisingly, it is found that the two-body observables associated with the Feshbach resonance can be insensitive to the pr…

Universality of Efimov states in highly mass-imbalanced cold-atom mixtures with van der Waals and dipole interactions Open
We study three-body systems in a mass-imbalanced, two-component, cold-atom mixture, and we investigate the three-body parameter of their Efimov states for both bosonic and fermionic systems, with a major focus on the Er-Er-Li Efimov states…

Inequivalence of stochastic and Bohmian arrival times in time-of-flight experiments Open
Motivated by a recent prediction [Com. Phys., 6, 195 (2023)] that time-of-flight experiments with ultracold atoms could test different interpretations of quantum mechanics, this work investigates the arrival times predicted by the stochast…

Mass Ratio Dependence of Three-Body Resonance Lifetimes in 1D and 3D Open
We present a theoretical study of resonance lifetimes in a two-component three-body system, specifically examining the decay of three-body resonances into a deep dimer and an unbound particle. Utilising the Gaussian expansion method togeth…

Mixed Bubbles in Bose-Bose Mixtures Open
Repulsive Bose-Bose mixtures are known to either mix or phase separate into pure components. Here we predict a mixed-bubble regime in which bubbles of the mixed phase coexist with a pure phase of one of the components. This is a beyond-mea…

Polaron bubble stabilised by medium-induced three-body interactions Open
Mixing two kinds of particles that repel each other usually results in either a homogeneous mixture when the repulsion is weak, or a complete phase separation of the two kinds when their repulsion is too strong. It is shown however that th…
