TL;DR: The GBAR project at CERN as mentioned in this paper measured the free fall acceleration of ultracold neutral anti hydrogen atoms in the terrestrial gravitational field, which consists preparing anti hydrogen ions (one antiproton and two positrons) and sympathetically cooling them with Be (+) ions.

TL;DR: The GBAR project as mentioned in this paper proposes to measure the free fall acceleration of neutral antihydrogen atoms in the terrestrial gravitational field by photoionizing them with Be+ ions to a few 10 μ K.
Journal ArticleDOI
Quantum reflection of antihydrogen from the Casimir potential above matter slabs
Gabriel Dufour,Antoine Gérardin,Romain Guérout,Astrid Lambrecht,Valery Nesvizhevsky,Serge Reynaud,A. Yu. Voronin +6 more
TL;DR: In this article, the van der Waals-Casimir-Polder potential of antihydrogen atoms from matter slabs was studied and the effect of reflection amplitude on the potential was analyzed.
Journal ArticleDOI
Totally Destructive Many-Particle Interference.
Christoph Dittel,Christoph Dittel,Gabriel Dufour,Mattia Walschaers,Gregor Weihs,Andreas Buchleitner,Robert Keil +6 more
TL;DR: In a general, multimode scattering setup, it is shown how the permutation symmetry of a many-particle input state determines those scattering unitaries that exhibit strictly suppressed many- particle transition events.
Journal ArticleDOI
Totally destructive interference for permutation-symmetric many-particle states
Christoph Dittel,Christoph Dittel,Gabriel Dufour,Mattia Walschaers,Gregor Weihs,Andreas Buchleitner,Robert Keil +6 more
TL;DR: In this article, Dittel et al. provide a detailed theoretical analysis that substantially expands on all aspects of this generalization: they prove the suppression laws put forward in their other paper, establish how they interrelate with forbidden single-particle transitions, show how all suppression laws hitherto known can be retrieved from their general formalism, and discuss striking differences between bosons and fermions.
