Researchers at the Paul Scherrer Institute examined around 25 billion ultracold neutrons and found no evidence of oscillation into mirror neutrons. The high-precision experiment largely rules out the hypothesis that neutrons disappear into a mirror world, a theoretical candidate for dark matter. The results set a new standard for such searches.

An international research team has observed Jahn-Teller polarons, unique quasiparticles, in cobalt oxide (Co₃O₄) crystals triggered by precisely tailored laser pulses. These polarons emerge through ultrafast electron transfer and local lattice distortions, dramatically influencing the material’s structural, electronic, and magnetic properties. Using advanced pump probe spectroscopy and theoretical modeling led by physicists at the Institute of Nuclear Physics of the Polish Ac

Researchers from Tsinghua University and Nanyang Technological University have achieved a major breakthrough in optical skyrmions — tiny topological “knots” of light that are highly promising for future high-capacity and secure data transmission.

By adapting an algorithm from the 1980s to mathematical objects called tensor networks, researchers at the Flatiron Institute show that classical computers can tackle a class of problems previously claimed to be solvable only by quantum computers

A team of researchers from the Max Born Institute, the Ferdinand Braun Institute, the University of Augsburg, and the Helmholtz-Zentrum Berlin has succeeded in directly imaging the effect of short current pulses on a skyrmion.

Theorists at the University of Illinois Urbana-Champaign address an experimental paradox by developing a general theory uniting a kind of order known as electronic nematicity with a crystal’s elasticity.
