Sensing the internal dynamics of delocalized molecules

Delocalization of massive objects is a fundamentally non-classical and non-intuitive phenomenon, which is clearly revealed in matter wave interferometry. It is often essential for  ...

A Kapitza-Dirac-Talbot-Lau Interferometer

We have developed and implemented a novel high-performance matter wave interferometer for massive molecules. The interferometer is based on the

Thermal Decoherence

Emergent quantum technologies have led to increasing interest in decoherence—the processes that limit the appearance of quantum effects and turn them into classical phenomena. One  ...

Wave nature of biomolecules and fluorinated fullerenes

We demonstrate quantum interference for tetraphenylporphyrin, the first biomolecule exhibiting wave nature, and for the fluorofullerene C60F48 using a near-field Talbot-Lau interfe ...

Collisional decoherence

One of the corner stones of quantum mechanics is the wave-particle duality of massive objects.According to quantum theory even complex particles, such as the C70 fullerene buckybal ...

An interferometer for large molecules

We demonstrate a near-field Talbot-Lau interferometer for C-70 fullerene molecules. Such interferometers are particularly suitable for larger masses. Using three free-standing gold ...

Molecule diffraction at light waves

We study the loss of spatial coherence in the extended wave function of fullerenes due to collisions with background gases. From the gradual suppression of quantum interference wit ...

Wave-particle duality of C60

Quantum superposition lies at the heart of quantum mechanics and gives rise to many of its paradoxes. Superposition of de Broglie matter waves1 has been observed for massive partic ...
