Reactions: Nobel Prize in Physics to Agostini, Krausz and L'Huillier for developing light pulses to study the motion of electrons in matter

The Royal Swedish Academy of Sciences has awarded the 2023 Nobel Prize in Physics to Pierre Agostini, Ferenc Krausz and Anne L'Huillier for developing "experimental methods generating attosecond light pulses". These advances made it possible to observe the motion of particles in atoms on the shortest time scale captured by humans. An attosecond is a unit of time equivalent to one trillionth of a second, roughly the time it takes light to travel the diameter of an atom.

Reactions: A study still pending review announces the first superconductor at room temperature and pressure

A team of South Korean researchers claims to have achieved a superconductor at room temperature and pressure for the first time in history. If true, it would mean a revolution in physics with implications for the whole of society. The material, called LK-99, is based on a copper-doped lead apatite framework. The article is a preprint and can be read in the ArXiv repository, where the research community shares their work before it is reviewed for publication in a scientific journal.

Reactions to experiment using neutrinos to understand quantum gravity

The IceCube collaboration, with its detector located under the Antarctic ice sheet, has used astrophysical neutrinos to search for changes in the structure of space-time. In the research, published in Nature Physics, the team analysed more than seven years of data and found no signs of a modified structure of space-time imprinted in the characteristics of these particles, a further step towards understanding quantum gravity.

The discovery of the Higgs boson turns 10 with an eye on what the future will bring

This week we celebrate not only the tenth anniversary of the discovery of the Higgs, but also Run 3: the Large Hadron Collider is back on line to collect a huge amount of data that opens the door to the discovery of new phenomena that could solve unsolved mysteries, such as understanding what makes up the dark matter that makes up 25% of the universe.

Ten years since the discovery of the Higgs boson: how it changed the history of physics

On 4 July 2012, physicists from all over the world celebrated the milestone achieved by CERN's Large Hadron Collider (LHC) in Geneva: they had found the elusive Higgs boson, described theoretically in 1964 and a key part of the standard model. Among the dozens of scientists who participated in that discovery, with the ATLAS and CMS experiments, there were many Spanish physicists, who ten years later appreciate what it meant.

 

Europe moves step by step towards fusion as an energy source

The Joint European Torus (JET) has achieved a relevant scientific milestone related to energy production from nuclear fusion reactions. The results confirm some of the technological options selected for the large international ITER experiment. Spain has proposed to build a scientific facility in Granada to develop materials with which to build future reactors.
