High-energy ion collisions at the Large Hadron Collider are capable of producing a quark-gluon plasma. But are heavy atomic nuclei really necessary for its formation? And above all: how are secondary particles later born from this plasma? Further clues in the search for answers to these questions are provided by the latest analysis of collisions between protons and protons or ions, observed in the LHCb experiment.
The counterintuitive effect, in which the brighter the laser light beam, the weaker the diffraction image has been explained by physicists from Japanese, Polish and German scientific institutions. Understanding this phenomenon gives hope for the production of laser pulses that have significantly shorter pulse duration than those currently available, reports the Institute of Nuclear Physics of the Polish Academy of Sciences, involved in the research project.
A scientist from the Warsaw University of Technology used the capabilities of the LUMI supercomputer to conduct research on fermions, giving hope for a deeper understanding of the processes taking place inside neutron stars, and research on quantum turbulence occurring in superfluid systems.
Polish researchers have developed luminescent nanomaterials that change the colour of emitted light with local pressure. Thanks to this, it will be possible to remotely and continuously monitor the distribution of stresses in structures and diagnose whether anything in them is starting to fail.
