A review is given on the foundations and applications of non-Hermitian classical and
quantum physics. First, key theorems and central concepts in non-Hermitian linear algebra …

A recent rejuvenation of experimental and theoretical interest in the physics of few-body
systems has provided deep, fundamental insights into a broad range of problems. Few-body …

Understanding strongly correlated phases of matter, such as the quark–gluon plasma and
neutron stars, and in particular the dynamics of such systems, for example, following a …

The notion of non-Hermitian optics and photonics rooted in quantum mechanics and
photonic systems has recently attracted considerable attention ushering in tremendous …

In many-body systems governed by pairwise contact interactions, a wide range of
observables is linked by a single parameter, the two-body contact, which quantifies two …

Chemical reactions in the quantum degenerate regime are described by the mixing of matter-
wave fields. In many-body reactions involving bosonic reactants and products, such as …

Using a combination of bound-state spectroscopy and loss spectroscopy, we pinpoint eight
intrastate Feshbach resonances in K 39, as well as six previously unexplored interstate …

Since the Efimov effect was introduced, a detailed theoretical understanding of Efimov
physics has been developed in the few-body context. However, it has proven challenging to …

We provide a general discussion on the importance of three-body Efimov physics for
strongly interacting ultracold quantum gases. Using the adiabatic hyperspherical …

We report on the observation of heteronuclear magnetic Feshbach resonances in several
isotope mixtures of the highly magnetic elements erbium and dysprosium. Among many …
