The theory of atomic collisions
TLDR
The perturbation theory has been applied to many-body problems and applications, such as electron collisions with atoms, collisions between atomic systems, nuclear collisions, and certain aspects of two-body systems under relativistic collisions.Abstract:
Volume II of this work covers many-body problems and applications of the theory to electron collisions with atoms, collisions between atomic systems, nuclear collisions, certain aspects of two-body systems under relativistic collisions, and the use of time-dependent perturbation theory. Despite the amount of work carried out since this book was first published, the underlying theory presented here remains both sound and of practical value to all theoretical physicists.read more

Unified theory of nuclear reactions
TL;DR: In this article, a new formulation of the theory of nuclear reactions based on the properties of a generalized "optical" potential is presented, where the real and imaginary part of this potential satisfy a dispersion type relation while its poles give rise to resonances in nuclear reactions.
Feshbach Resonances in Ultracold Gases
TL;DR: Feshbach resonances are the essential tool to control the interaction between atoms in ultracold quantum gases and have found numerous experimental applications, opening up the way to important breakthroughs as mentioned in this paper.

Ultralight scalars as cosmological dark matter
TL;DR: Fuzzy dark matter (FDM) as discussed by the authorsDM is an alternative to CDM, which is an extremely light boson having a de Broglie wavelength inside the galaxy.
