Principles and Design of a Zeeman–Sisyphus Decelerator for Molecular Beams [PDF]
ChemPhysChem, 2016 Escher meets Sisyphus: A deceleration technique for molecular beams is explored that relies on repeated optical pumping in a static, spatially varying, magnetic field. Molecules are pumped between weak‐ and strong‐field seeking states so that they are always climbing potential hills (see picture).

Ultrafast control of moiré pseudo‐electromagnetic field in homobilayer semiconductors
Natural Sciences, Volume 2, Issue 2, April 2022., 2022 Spatial‐temporal modulation of layer pseudospin in moiré of homobilayer semiconductors with bias pulse or terahertz irradiation generates ultrafast pseudo‐electromagnetic responses for valley‐spintronic applications. Abstract In long‐wavelength moiré patterns of homobilayer semiconductors, the layer pseudospin of electrons is subject to a sizable ...

Expanding Nuclear Physics Horizons with the Gamma Factory
Annalen der Physik, Volume 534, Issue 3, March 2022., 2022 The Gamma Factory is an ambitious proposal for a source of photons with energies up to hundreds of MeV and photon fluxes exceeding those of the currently available gamma sources by orders of magnitude. The paper surveys the new opportunities in nuclear physics and related fields that may be afforded by the this facility. Abstract The Gamma Factory (GF)

A Multi‐Purpose Heliophysics L4 Mission
Space Weather, Volume 19, Issue 9, September 2021., 2021 Abstract The Earth‐Sun Lagrangian point 4 is a meta‐stable location at 1 AU from the Sun, 60° ahead of Earth's orbit. It has an uninterrupted view of the solar photosphere centered on W60, the Earth's nominal magnetic field connection to the Sun. Such a mission on its own would serve as a solar remote sensing observatory that would oversee the entire ...

Advanced Quantum Technologies, Volume 3, Issue 11, November 2020., 2020 The properties of an optical dipole trap for single atoms when focusing the trapping beam from full solid angle with a deep parabolic mirror are described. The calculations yield favorable trap characteristics, which could prove to be beneficial for light–matter‐interaction experiments with neutral atoms and applications in quantum technology ...
