چکیده

We discuss the stability of homonuclear and heteronuclear mixtures of 3He and 4He atoms in the metastable 2 S1 state (He∗) and predict positions and widths of Feshbach resonances by using the asymptotic-bound-state model. All calculations are performed without fit parameters, using ab initio calculations of molecular potentials. One promising very broad Feshbach resonance ( B = 72.9+18.3 −19.3 mT) is found that allows for tuning of the interisotope scattering length.

Bosons and Fermions near Feshbach resonances

Near Feshbach resonances, n|a|3 ≫ 1, systems of Bose and Fermi particles become strongly interacting/dense. In this unitary limit both bosons and fermions have very different properties than in a dilute gas, e.g., the energy per particle approach a value h̄n2/3/m times an universal many-body constant. Calculations based upon an approximate Jastrow wave function can quantitatively describe recent...

Photoassociation as a probe of Feshbach resonances in cold-atom scattering

We investigate theoretically the influence of magnetically tunable Feshbach collision resonances on the photoassociation spectra of ultracold atoms. As an example we consider recently predicted resonances for Rb atoms. For excitation to the Rb2 0g (S1/21P1/2) electronic state, we predict that the photoassociation rate is resonantly enhanced by at least two orders of magnitude. We find that phot...

Feshbach Resonances in Ultracold Gases

Feshbach resonances are the essential tool to control the interaction between atoms in ultracold quantum gases. They have found numerous experimental applications, opening up the way to important breakthroughs. This Review broadly covers the phenomenon of Feshbach resonances in ultracold gases and their main applications. This includes the theoretical background and models for the description o...

Controlling magnetic Feshbach resonances in polar open-shell molecules with nonresonant light.

Magnetically tunable Feshbach resonances for polar paramagnetic ground-state diatomics are too narrow to allow for magnetoassociation starting from trapped, ultracold atoms. We show that nonresonant light can be used to engineer the Feshbach resonances in their position and width. For nonresonant field intensities of the order of 10(9) W/cm(2), we find the width to be increased by 3 orders of m...

Feshbach spectroscopy and analysis of the interaction potentials of ultracold sodium

We have studied magnetic Feshbach resonances in an ultracold sample of Na prepared in the absolute hyperfine ground state. We report on the observation of three s-, eight d-, and three g-wave Feshbach resonances, including a more precise determination of two known s-wave resonances, and one s-wave resonance at a magnetic field exceeding 200 mT. Using a coupled-channels calculation we have impro...
