Static properties of a Fermi gas of cooled atoms near a wide Feshbach resonance
, 2011 We introduce the Global Spin Model (GSM) to study the static properties of the ultracold fermionic gas near the broad Feshbach resonance. We solve the model and find the densities of the BE and BCS condensates as well as their correlation in the vicinity

An analytic approach to probability tables for the unresolved resonance region
EPJ Web of Conferences, 2017 The Unresolved Resonance Region (URR) connects the fast neutron region with the Resolved Resonance Region (RRR). The URR is problematic since resonances are not resolvable experimentally yet the fluctuations in the neutron cross sections play a ...

Many Bosons in a Narrow Magnetic Feshbach Resonance [PDF]
Physical Review Letters, 2013 The many-boson problem in presence of an asymptotically narrow Feshbach resonance is considered. The low energy properties are investigated using a two-channel Hamiltonian. The energy spectrum of this model is shown to be bounded from below in the limit of zero range interaction.

Three-body Universality Controlled by a Feshbach Resonance
, 2023 The quantum Efimov effect manifests itself in the limit of resonant two-body interactions, where the scattering length diverges. In this scenario, an infinite number of shallow bound trimer states are formed with binding energies that obey a discrete ...

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

Universal Quantum Dynamics of Bose Polarons
Physical Review XPredicting the emergent properties of impurities immersed in a quantum bath is a fundamental challenge that can defy quasiparticle treatments. Here, we measure the spectral properties and real-time dynamics of mobile impurities injected into a weakly ...

Induced two-body scattering resonances from a square-well potential with oscillating depth
EPJ Web of Conferences, 2016 In systems of ultracold atoms, pairwise interactions can be resonantly enhanced by a new mechanism which does not rely upon a magnetic Feshbach resonance.

Nonequilibrium dynamics and atom-pair coherence in strongly interacting Bose-Fermi mixtures
Physical Review ResearchTheoretical treatments of nonequilibrium dynamics in strongly interacting Bose-Fermi mixtures are complicated by the inherent non-Gaussian nature of the vacuum two-body physics, invalidating the typical Hartree-Fock-Bogoliubov approximation.
