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

Interference with atomic and molecular matter waves is a rich branch of atomic physics and
quantum optics. It started with atom diffraction from crystal surfaces and the separated …

The quantum superposition principle allows massive particles to be delocalized over distant
positions. Though quantum mechanics has proved adept at describing the microscopic …

Deployment of ultracold atom interferometers (AI) into space will capitalize on quantum
advantages and the extended freefall of persistent microgravity to provide high-precision …

Bose-Einstein condensation of cesium atoms is achieved by evaporative cooling using
optical trapping techniques. The ability to tune the interactions between the ultracold atoms …

A trapped-atom interferometer was demonstrated using gaseous Bose-Einstein
condensates coherently split by deforming an optical single-well potential into a double-well …

We have developed a matter wave interferometer based on the diffraction of atoms from
effective absorption gratings of light. In a setup with cold rubidium atoms in an atomic …

Seeing macroscopic quantum states directly remains an elusive goal. Particles with boson
symmetry can condense into quantum fluids, producing rich physical phenomena as well as …

We present up to 24-photon Bragg diffraction as a beam splitter in light-pulse atom
interferometers to achieve the largest splitting in momentum space so far. Relative to the 2 …

We demonstrate a precise magnetic microscope based on direct imaging of the Larmor
precession of a Rb 87 spinor Bose-Einstein condensate. This magnetometer attains a field …
