DOI: 10.1016/j.actaastro.2017.03.012
Abstract: Abstract The prime candidate for fueling relativistic starships is antimatter and reaching the stars will require antimatter storage on board of a spacecraft in a compact form, most likely liquid or solid antihydrogen. The problem… read more here.

DOI: 10.1038/s41586-018-0017-2
Abstract: In 1928, Dirac published an equation1 that combined quantum mechanics and special relativity. Negative-energy solutions to this equation, rather than being unphysical as initially thought, represented a class of hitherto unobserved and unimagined particles—antimatter. The… read more here.

DOI: 10.1088/1367-2630/aabc71
Abstract: The formation of antihydrogen atoms from antiprotons injected into a positron plasma is simulated, focussing on the fraction that fulfil the conditions necessary for confinement of anti-atoms in a magneticminimum trap. Trapping fractions of around… read more here.

DOI: 10.1088/1367-2630/ab2bdc
Abstract: The formation of a beam of antihydrogen atoms when antiprotons pass through cold, dense positron plasmas is simulated for various plasma properties and antiproton injection energies. There are marked dependences of the fraction of injected… read more here.

DOI: 10.1088/1748-0221/14/05/p05009
Abstract: A low energy antiproton transport from the ASACUSA antiproton accumulation trap (MUSASHI trap) to the antihydrogen production trap (double cusp trap) is developed. The longitudinal antiproton energy spread after the transport line is 0.23 +-… read more here.

DOI: 10.1098/rsta.2017.0268
Abstract: Both the 1S–2S transition and the ground state hyperfine spectrum have been observed in trapped antihydrogen. The former constitutes the first observation of resonant interaction of light with an anti-atom, and the latter is the… read more here.

DOI: 10.1103/physrevd.98.035020
Abstract: Surveys of diffuse $\gamma$-ray in the interstellar medium (ISM) can be used to probe hydrogen-antihydrogen oscillations, by detecting the $\gamma$-ray emission from antihydrogen annihilation. A bound on the oscillation parameter $\delta$ was originally derived by… read more here.

DOI: 10.1103/physrevlett.120.133205
Abstract: Experiments with antihydrogen (H[over ¯]) for a study of matter-antimatter symmetry and antimatter gravity require ultracold H[over ¯] to reach ultimate precision. A promising path towards antiatoms much colder than a few kelvin involves the… read more here.
