  journal={Reviews of Modern Physics},
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 gratings, and at ionizing laser fields are considered. We discuss the theoretical concepts underlying these experiments and the experimental challenges. This includes optimizing interferometer designs as well as understanding the role of decoherence… 

Perspectives for quantum interference with biomolecules and biomolecular clusters

Modern quantum optics encompasses a wide field of phenomena that are either related to the discrete quantum nature of light, the quantum wave nature of matter or light–matter interactions. We here

Multiphoton absorption in optical gratings for matter waves

We present a theory for the diffraction of large molecules or nanoparticles at a standing light wave. Such particles can act as a genuine photon absorbers due to their numerous internal degrees of

Matter-wave physics with nanoparticles and biomolecules

The chapter discusses advances in matter-wave optics with complex molecules, generalizing Young’s double slit to high masses. The quantum wave-particle duality is visualized by monitoring the arrival

Near-Field Interference Techniques with Heavy Molecules and Nanoclusters

We will now devote our attention to one of the boldest enterprises in the field of matter-wave physics: Single-particle interference experiments with large molecules and clusters far beyond a single

A universal matter-wave interferometer with optical ionization gratings in the time-domain

The experimental realization of a universal near-field interferometer built from three short-pulse single-photon ionization gratings, which is sensitive to fringe shifts as small as a few nanometers and yet robust against velocity-dependent phase shifts, since the gratings exist only for nanoseconds and form an interferometers in the time-domain.

Experimental methods of molecular matter-wave optics

We describe the state of the art in preparing, manipulating and detecting coherent molecular matter. We focus on experimental methods for handling the quantum motion of compound systems from diatomic

Erratum: Coherence in the presence of absorption and heating in a molecule interferometer

Evidence that center-of-mass coherence can be maintained even when the internal energy and entropy of the interfering particle are substantially increased by absorption of photons from a standing light wave is provided.

Real-time single-molecule imaging of quantum interference.

This work shows how a combination of nanofabrication and nano-imaging allows us to record the full two-dimensional build-up of quantum interference patterns in real time for phthalocyanine molecules and for derivatives of phthaloprotein molecules, which have masses of 514 AMU and 1,298 AMu respectively.

Interference and Interferometry

The existence of wavy properties associated with material particles is one of the fundamental achievements of quantum mechanics. Thus, the experimental use of single, double, or multiple slits has



A Kapitza–Dirac–Talbot–Lau interferometer for highly polarizable molecules

Research on matter waves is a thriving field of quantum physics and has recently stimulated many investigations with electrons1, neutrons2, atoms3, Bose-condensed ensembles4, cold clusters5 and hot

Quantum interference of large organic molecules

It is shown that even complex systems, with more than 1,000 internal degrees of freedom, can be prepared in quantum states that are sufficiently well isolated from their environment to avoid decoherence and to show almost perfect coherence.

Concept of an ionizing time-domain matter-wave interferometer

We discuss the concept of an all-optical and ionizing matter-wave interferometer in the time domain. The proposed setup aims at testing the wave nature of highly massive clusters and molecules, and

Quantum interference experiments with large molecules

Wave–particle duality is frequently the first topic students encounter in elementary quantum physics. Although this phenomenon has been demonstrated with photons, electrons, neutrons, and atoms, the

Optics and interferometry with Na2 molecules.

An intense, pure beam of sodium molecules (Na2) is produced by using light forces to separate the atomic and molecular species in a seeded supersonic beam using diffraction from a microfabricated grating and a molecule interferometer with fully separated beams and high contrast fringes.

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

Diffraction of complex molecules by structures made of light.

It is demonstrated that structures made of light can be used to coherently control the motion of complex molecules and the principles of this effect can be successfully extended to massive and large molecules which are internally in a thermodynamic mixed state and which do not exhibit narrow optical resonances.

Matter-wave interferometer for large molecules.

A near-field Talbot-Lau interferometer for C70 fullerene molecules using three free-standing gold gratings of 1 microm period and a transversally incoherent but velocity-selected molecular beam achieves an interference fringe visibility of 40% with high count rate.

Influence of molecular temperature on the coherence of fullerenes in a near-field interferometer

We study ${\mathrm{C}}_{70}$ fullerene matter waves in a Talbot-Lau interferometer as a function of their temperature. While the ideal fringe visibility is observed at moderate molecular

Atom interferometry

In this paper, we present a brief overview of atom interferometry. This field of research has developed very rapidly since 1991. Atom and light wave interferometers present some similarities but
