Atom Interferometry for Detection of Gravitational Waves

Dephasing dynamics of Rydberg atom spin waves

A theory of Rydberg atom interactions is used to derive analytical forms for the spin-wave pair correlation function in laser-excited cold-atom vapors. This function controls the quantum statistics of light emission from dense, inhomogeneous clouds of cold atoms of various spatial dimensionalities. The results yield distinctive scaling behaviors on the microsecond time scale, including generali...

Shock Waves in an Augmented One-Dimensional Atom Chain

We derive here a simplified discrete one-dimensional (1D) model describing the main features of shock waves. In order to avoid expensive multidimensional simulations, 1D models are commonly used, but the existing ones often exhibit some spurious physically irrelevant behavior. Here we build a 1D model with perturbations arising from mean higher-dimensional behavior. The coupling of the system w...

Nonlinear Atom Optics: Multi-wave mixing with matter waves

Fourier-expansion solution of atom distributions in a crystal using X-ray standing waves.

Term-by-term Fourier-expansion series, each made up of components having element-specific phases and amplitudes acquired with x-ray standing wave measurements on successive orders of Bragg reflections, are used to reconstruct impurity atom distributions in muscovite mica with respect to the (001) lattice without a priori assumptions on their structures.
