Critical correlations in an ultracold Bose gas revealed by means of a temporal Talbot-Lau interferometer

, 2013
We study experimentally the critical correlation in an ultra-cold Bose gas with a temporal Talbot-Lau (TL) interferometer. Near the critical temperature, we observe a bi-modal density distribution in an ultra-cold Bose gas after the application of the TL

Deformable image registration of dark‐field chest radiographs for functional lung assessment

Medical Physics, Volume 52, Issue 8, August 2025.
Abstract Background Dark‐field radiography of the human chest has been demonstrated to have promising potential for the analysis of the lung microstructure and the diagnosis of respiratory diseases. However, most previous studies of dark‐field chest radiographs evaluated the lung signal only in the inspiratory breathing state.

Isotope-selective high-order interferometry with large organic molecules in free fall

New Journal of Physics, 2018
Interferometry in the time domain has proven valuable for matter-wave based measurements. This concept has recently been generalized to cold molecular clusters using short-pulse standing light waves which realized photo-depletion gratings, arranged in a ...

Testing spontaneous localization theories with matter-wave interferometry

, 2011
We propose to test the theory of continuous spontaneous localization (CSL) in an all-optical time-domain Talbot-Lau interferometer for clusters with masses exceeding 1000000 amu.

Atom Interferometers [PDF]

, 2007
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 oscillatory fields technique used in atomic clocks. Atom interferometry is

A charged particle Talbot-Lau interferometer and magnetic field sensing

, 2013
We present the first demonstration of a three grating Talbot-Lau interferometer for electrons. As a proof of principle, the interferometer is used to measure magnetic fields. The device is similar to the classical Moire deflectometer. The possibility to extend this work to build a scaled-up charged particle deflectometer or interferometer for sensitive

The wave nature of biomolecules and fluorofullerenes

, 2003
We demonstrate quantum interference for tetraphenylporphyrin, the first biomolecule exhibiting wave nature, and for the fluorofullerene C60F48 using a near-field Talbot-Lau interferometer. For the porphyrins, which are distinguished by their low symmetry

Nanoparticle Interferometer by Throw and Catch

Atoms
Matter wave interferometry with increasingly larger masses could pave the way to understanding the nature of wavefunction collapse, the quantum to classical transition, or even how an object in a spatial superposition interacts with its gravitational ...

Colloquium: Quantum interference of clusters and molecules

, 2012
We review recent progress and future prospects of matter wave interferometry with complex organic molecules and inorganic clusters. Three variants of a near-field interference effect, based on diffraction by material nanostructures, at optical phase ...
