Feshbach resonances are the essential tool to control the interaction between atoms in
ultracold quantum gases. They have found numerous experimental applications, opening up …

In this review, we discuss the properties of a few impurity atoms immersed in a gas of
ultracold fermions—the so-called Fermi polaron problem. On one hand, this many-body …

After a recent series of rapid and exciting developments, the long search for the Majorana
fermion—the elusive quantum entity at the border between particles and antiparticles—has …

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 …

This article reviews theoretical and experimental developments for one-dimensional Fermi
gases. Specifically, the experimentally realized two-component delta-function interacting …

The control of physical systems and their dynamics on the level of individual quanta
underpins both fundamental science and quantum technologies. Trapped atomic and …

We report on the observation of controllable phase separation in a dual-species Bose-
Einstein condensate with Rb 85 and Rb 87. Interatomic interactions between the different …

We present a theory of a degenerate atomic Fermi gas, interacting through a narrow
Feshbach resonance, whose position and therefore strength can be tuned experimentally …

This book covers the fundamentals of and new developments in gaseous Bosendash;
Einstein condensation. It begins with a review of fundamental concepts and theorems, and …

We propose to use the recently predicted two-dimensional “weak-pairing” px+ ipy superfluid
state of fermionic cold atoms as a platform for topological quantum computation. In the core …
