Unveiling the Energy Threshold for Exotic Quark-Gluon Plasma Formation

Physicists have discovered that the creation of quark-gluon plasma (QGP), an exotic state of matter, ceases at the lowest collision energy of 3 GeV. By colliding gold nuclei at varying energies, scientists have mapped out the boundaries between QGP and the hadronic phase, providing insights into the conditions for QGP existence and its transition from ordinary matter. The findings will aid in understanding the phases of nuclear matter and the temperature and density conditions under which QGP can exist.

Unveiling the Properties of Hydrogen at Extreme Pressures.

Researchers have created a highly accurate phase diagram of high-pressure hydrogen using advanced computational tools, which could inform ongoing efforts aimed at creating atomic metallic hydrogen. The study suggests that hydrogen starts acquiring metallic properties progressively as the pressure rises and shows why previous experiments may have been unsuccessful in attaining atomic metallic hydrogen. The researchers also presented a complete and exhaustive spectroscopic characterization of hydrogen, which could inform future research efforts aimed at observing hydrogen in its atomic metallic phase.
