Feshbach resonances in ultracold gases [PDF]

, 2014
In this chapter, we describe scattering resonance phenomena in general, and focus on the mechanism of Feshbach resonances, for which a multi-channel treatment is required.

Feshbach resonances in ultracold gases [PDF]

Reviews of Modern Physics, 2008
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.

Dispersive optical detection of magnetic Feshbach resonances in ultracold gases. [PDF]

Phys Rev A (Coll Park), 2017
Magnetically tunable Feshbach resonances in ultracold atomic systems are chiefly identified and characterized through time-consuming atom loss spectroscopy.

Investigation of Feshbach resonances in ultracold ⁴⁰K spin mixtures. [PDF]

Phys Rev A (Coll Park), 2017
Magnetically tunable Feshbach resonances are an indispensable tool for experiments with atomic quantum gases. We report on 37 thus far unpublished Feshbach resonances and four further probable Feshbach resonances in spin mixtures of ultracold fermionic ...

Cyclic Lattice Feshbach Resonances [PDF]

Physical Review B, 2006
In this Letter we illustrate the possible cyclic fermion pairing states across Feshbach resonances in optical lattices. In cyclic fermion pairing, the pairing amplitude exhibits an oscillatory behavior as the detuning varies.

Probing the activated complex of the F + NH3 reaction via a dipole-bound state [PDF]

Nature Communications
Experimental characterization of the transition state poses a significant challenge due to its fleeting nature. Negative ion photodetachment offers a unique tool for probing transition states and their vicinity.

Feshbach resonances and weakly bound molecular states of boson-boson and boson-fermion NaK pairs [PDF]

, 2016
We study theoretically magnetically induced Feshbach resonances and near-threshold bound states in isotopic NaK pairs. Our calculations accurately reproduce Feshbach spectroscopy data on Na$^{40}$K and explain the origin of the observed multiplets in the

Reshaped three-body interactions and the observation of an Efimov state in the continuum [PDF]

Nature Communications
Efimov trimers are exotic three-body quantum states that emerge from the different types of three-body continua in the vicinity of two-atom Feshbach resonances. In particular, as the strength of the interaction is decreased to a critical point, an Efimov

Bosons and Fermions near Feshbach resonances [PDF]

Journal of Physics B: Atomic, Molecular and Optical Physics, 2003
Near Feshbach resonances, $n|a|^3\gg 1$, 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 ...

Characterizing Feshbach resonances in ultracold scattering calculations. [PDF]

Physical Review A, 2017
We describe procedures for converging on and characterizing zero-energy Feshbach resonances that appear in scattering lengths for ultracold atomic and molecular collisions as a function of an external field.
