Physicists from the STAR Collaboration at the Relativistic Heavy Ion Collider, an atom smasher at Brookhaven National Laboratory, have tracked pairs of positively and negatively charged kaons — the decay products of phi mesons, made of two quarks held together by the exchange of gluons — and found that these mesons have a preference for one among three possible spin states. The phi meson is made of a strange quark and strange antiquark...

Kapil et al. describe the phase behavior of monolayer-confined water by calculating its pressure-temperature phase diagram: (a-g) the pressure-temperature phase diagram of monolayer water was calculated using an machine learning potential that delivers first-principles accuracy; the solid and dashed lines indicate first-order and continuous phase transitions, respectively; the gray regions indicate the statistical uncertainty for solid-solid phase transitions and, for the other transitions, the uncertainties arising from studying a finite number of thermodynamic states; the diagonally hatched area indicates the region in which square and flat-rhombic phases are near degenerate; diagrams of the hexagonal (a), pentagonal (b), square (c), flat-rhombic (d), hexatic (e), superionic (f) and liquid (g) phases are shown with oxygen atoms in red, hydrogen atoms in gray and hydrogen bonds shown by blue lines.
