Alkaline-earth atoms have metastable 'clock'states with minute-long optical lifetimes, high-
spin nuclei and SU (N)-symmetric interactions, making them powerful platforms for atomic …

We present a method for solving few-body problems for trapped particles and apply it to
three equal-mass particles in a one-dimensional harmonic trap, interacting via a contact …

I consider nonrelativistic bosons interacting via pairwise potentials with infinite scattering
length and supporting no two-body bound states. To lowest order in effective field theory …

We provide accurate expressions for the s-wave scattering length for a Gaussian potential
well in one, two, and three spatial dimensions. The Gaussian potential is widely used as a …

This review article presents historical developments and recent advances in our
understanding on the three-body forces and Efimov physics, from an interdisciplinary …

The transition from “few to many” has recently been probed experimentally in an ultracold
harmonically confined one-dimensional lithium gas, in which a single impurity atom interacts …

When describing the low-energy physics of bosons in a double-well potential with a high
barrier between the wells and sufficiently weak atom-atom interactions, one can, to a good …

The coupling between the spin degrees of freedom and the orbital angular momentum has a
profound effect on the properties of nuclei, atoms, and condensed-matter systems. Recently …

We develop the perturbation theory for bosons interacting via a weak two-body potential V,
attractive and repulsive parts of which cancel each other. We find that the leading …

We study the dynamics of interacting superfluid bosons in a one-dimensional vertical optical
lattice after a sudden increase of the lattice potential depth. We show that this system can be …
