At very low energies, a light neutral particle above a horizontal surface can experience quantum reflection. The quantum reflection holds the particle against gravity and leads to gravitational quantum states (gqs). So far, gqs were only observed with neutrons as pioneered by Nesvizhevsky and his collaborators at ill.

Synopsis of recent research by authors named "Katharina Schreiner"

  • - Katharina Schreiner's recent research focuses on the groundbreaking exploration of gravitational quantum states (GQS) of atoms, specifically utilizing cold hydrogen and deuterium beams to demonstrate and characterize these states, which were previously only observed with neutrons.
  • - In her article from March 2023, Schreiner discusses the phenomenon of quantum reflection at low energies, explaining how it enables light neutral particles to resist gravitational pull and enter gravitational quantum states, paving the way for future experimental validations.
  • - Her upcoming publication in October 2024 aims to further substantiate the existence of GQS in atoms by detailing the shaping and characterization of cold hydrogen and deuterium beams, thus advancing the field of quantum mechanics and the understanding of atomic behavior in gravitational fields.
