In this article, the authors reported experimental observation of this long predicted but experimentally elusive Efimov state by means of Coulomb explosion imaging, confirming the predicted size and a typical structure where two atoms are close to each other while the third is far away.Abstract:
Quantum theory dictates that upon weakening the two-body interaction in a three-body system, an infinite number of three-body bound states of a huge spatial extent emerge just before these three-body states become unbound. Three helium atoms have been predicted to form a molecular system that manifests this peculiarity under natural conditions without artificial tuning of the attraction between particles by an external field. Here we report experimental observation of this long predicted but experimentally elusive Efimov state of $^{4}$He$_{3}$ by means of Coulomb explosion imaging. We show spatial images of an Efimov state, confirming the predicted size and a typical structure where two atoms are close to each other while the third is far away.read more

Efimov Physics: a review
Pascal Naidon,Shimpei Endo +1 more
TL;DR: In this article, the authors review theoretical and experimental advances in Efimov physics, an array of quantum few-body and many-body phenomena arising for particles interacting via short-range resonant interactions, that is based on the appearance of a scale-invariant three-body attraction theoretically discovered by VitalyEfimov in 1970.

Observation of the Efimovian expansion in scale-invariant Fermi gases
TL;DR: The theoretical prediction and experimental observation of a distinct type of expansion dynamics for scale-invariant quantum gases is reported, which shares the same scaling law and mathematical description as the Efimov effect.

TL;DR: Beyond the quantum limit (QL), the log-periodic oscillations involving up to five oscillating cycles on the magnetoresistance of high-quality single-crystal ZrTe5 are observed, virtually showing the clearest feature of discrete scale invariance (DSI).

TL;DR: It is shown that even incomplete fragmentation pathways of individual molecules from a racemic CHBrClF sample can give access to the absolute configuration in CEI, leading to a significant increase of the applicability of the method as compared to the previously reported complete break up into atomic ions.

Four-Body Scale in Universal Few-Boson Systems.

TL;DR: It is found that at next-to-leading order (NLO) a four-body force is needed to obtain renormalized results for binding energies, and with the associated parameter fixed to the binding energy of the four-boson system, this force is shown to renormalize the five- and six-body systems as well.

TL;DR: In this article, the Efimov trimer state was shown to exist in an ultracold gas of caesium atoms and its signature was observed as a giant three-body recombination loss when the strength of the two-body interaction is varied.
