Optical polarizabilities of large molecules measured in near-field interferometry
Lucia Hackermueller, Klaus Hornberger, Stefan Gerlich +3
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…
Detecting Dark Domain Walls
Kate Clements, Benjamin Elder, Lucia Hackermueller +2
Light scalar fields, with double well potentials and direct matter couplings, undergo density driven phase transitions, leading to the formation of domain walls. Such theories coul…
Influence of molecular temperature on the coherence of fullerenes in a near-field interferometer
Klaus Hornberger, Lucia Hackermueller, Markus Arndt
We study C70 fullerene matter waves in a Talbot-Lau interferometer as a function of their temperature. While the ideal fringe visibility is observed at moderate molecular temperatu…
Exploiting complex 3D-printed surface structures for portable quantum technologies
Nathan Cooper, David Johnson, Benjamin Hopton +8
Portable quantum technologies require robust, lightweight apparatus with superior performance. For techniques dependent upon high-vacuum environments, such as atom interferometers…
Cold atoms in micromachined waveguides: a new platform for atom-photon interaction
Elisa Da Ros, Nathan Cooper, Jonathan Nute +1
Hybrid quantum devices, incorporating both atoms and photons, can exploit the benefits of both to enable scalable architectures for quantum computing and quantum communication, as…
The wave nature of biomolecules and fluorofullerenes
Lucia Hackermueller, Stefan Uttenthaler, Klaus Hornberger +4
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 observed in matter wave interferometry
Klaus Hornberger, Stefan Uttenthaler, Bjoern Brezger +3
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…
Decoherence of matter waves by thermal emission of radiation
Lucia Hackermueller, Klaus Hornberger, Bjoern Brezger +2
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. On…
Decoherence in a Talbot Lau interferometer: the influence of molecular scattering
Lucia Hackermueller, Klaus Hornberger, Bjoern Brezger +2
We study 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…
Terrestrial Very-Long-Baseline Atom Interferometry: Summary of the Second Workshop
Adam Abdalla, Mahiro Abe, Sven Abend +307
This summary of the second Terrestrial Very-Long-Baseline Atom Interferometry (TVLBAI) Workshop provides a comprehensive overview of our meeting held in London in April 2024, build…
A Kapitza-Dirac-Talbot-Lau interferometer for highly polarizable molecules
Stefan Gerlich, Lucia Hackermueller, Klaus Hornberger +8
Research on matter waves is a thriving field of quantum physics and has recently stimulated many investigations with electrons, neutrons, atoms, Bose-condensed ensembles, cold clus…
