Challenges for the Periodic Systems of Elements: Chemical, Historical and Mathematical Perspectives.
It is shown that ordered hypergraphs may solve current issues such as order reversals in super-heavy elements and lack of system predictive power, and proposes bringing back chemistry to the systems by exploring similarity and order relationships of elements using the current information of the chemical space.
And there was light
I discuss the use of light as a collection of real and virtual photons to study lingering questions in particle and nuclear physics.
Precision experiments with antihydrogen: an outlook
After a first generation of experiments has demonstrated the feasibility of forming - in a controlled manner - low-energy antihydrogen atoms via several different techniques, a second generation of


A possible new scheme to synthesize antihydrogen and to prepare a polarised antihydrogen beam
A new scheme is proposed for synthesizing antihydrogen by trapping positrons at the centre of a field consisting of a magnetic quadrupole and an electric octupole. It is expected that the total
Background-free observation of cold antihydrogen with field-ionization analysis of its states.
A background-free observation of cold antihydrogen atoms is made using field ionization followed by antiproton storage, a detection method that provides the first experimental information aboutAntihydrogen atomic states, suggesting that the antiHydrogen is formed via three-body recombination.
Production and detection of cold antihydrogen atoms
This work demonstrates the production of antihydrogen atoms at very low energy by mixing trapped antiprotons and positrons in a cryogenic environment and detects the neutral anti-atoms directly when they escape the trap and annihilate, producing a characteristic signature in an imaging particle detector.
