Atomic diffraction by patterned holes in hexagonal boron nitride: a comparison between semi-classical and quantum computational models
Eivind Kristen Osestad, Ekaterina Zossimova, Michael Walter +1
The diffraction of atoms and molecules through tiny, sub-nanometre holes in atomically thin membranes is a promising approach for advancing atom interferometry sensing and atomic h…
Quantum Reflection Effects in the Diffraction of Matter Waves
Johannes Fiedler, Eivind K. Osestad, Fabian Spallek +3
Among the fundamental quantum effects, quantum reflection (QR) is one of the most notable phenomena. Approximating arbitrary potentials in the Schrödinger equation as multistep po…
Atomic diffraction by nanoholes in hexagonal boron nitride
Eivind Kristen Osestad, Ekaterina Zossimova, Michael Walter +2
Fabricating patterned nanostructures with matter waves can help to realise new nanophotonic devices. However, due to dispersion effects, designing patterns with nanoscale features…
A novel gas sensing principle based on quantum fluctuations
Eivind Kristen Osestad, Pekka Parviainen, Johannes Fiedler
We present a model of a novel measurement scheme to detect small amounts of a gas species via the ground-state fluctuations of the electromagnetic field (dispersion forces) dependi…
