We demonstrate a near-field Talbot-Lau interferometer for C70 fullerene molecules. Such interferometers are particularly suitable for larger masses. Using three free-standing gold gratings of 1 microm period and a transversally incoherent but velocity-selected molecular beam, we achieve an interference fringe visibility of 40% with high count rate. Both the high visibility and its velocity dependence are in good agreement with a quantum simulation that takes into account the van der Waals…

Concepts for near-field interferometers with large molecules
We study the theory behind a Talbot–Lau interferometer. This consists of three gratings in each other’s Fresnel near field and accepts spatially incoherent illumination. Our formalism gives a clear
Refined model for Talbot–Lau matter-wave optics with pulsed photodepletion gratings
We analyze time-domain Talbot–Lau interferometry of organic cluster beams that are exposed to pulsed photodepletion gratings in the vacuum ultraviolet. We focus particularly on the analysis of the
Decoherence in a Talbot–Lau interferometer: the influence of molecular scattering
This work describes the interference of C70 fullerenes in a Talbot–Lau interferometer with a large separation between the diffraction gratings. This permits the observation of recurrences of the
Optical polarizabilities of large molecules measured in near-field interferometry
We discuss a novel application of matter wave interferometry to characterize the scalar optical polarizability of molecules at 532 nm. The interferometer presented here consists of two material
From classical xenon fringes to hydrogen interferometry
A setup with three equally spaced transmission gratings can be described as a moire deflectometer in the classical regime and as a Talbot–Lau interferometer in the quantum regime. We successfully
New avenues for matter-wave-enhanced spectroscopy
We present matter-wave interferometry as a tool to advance spectroscopy for a wide class of nanoparticles, clusters and molecules. The high sensitivity of de Broglie interference fringes to external
New Prospects for de Broglie Interferometry
We consider various effects that are encountered in matter wave interference experiments with massive nanoparticles. The text-book example of far-field interference at a grating is compared with
A Quantum Ruler for Magnetic Deflectometry
Matter-wave near-field interference can imprint a nano-scale fringe pattern onto a molecular beam, which allows observing its shifts in the presence of even very small external forces. Here we
Talbot-Lau effect beyond the point-particle approximation
Recent progress in matter-wave interferometry aims to directly probe the quantum properties of matter on ever increasing scales. However, in order to perform interferometric experiments with massive
Photofragmentation beam splitters for matter-wave interferometry.
It is proposed that photofragmentation gratings can act on a large set of van der Waals clusters and biomolecules which are thermally unstable and often resilient to single-photon ionization.
