Reversible electric control unlocks persistent chiral phonon states
Atoms in a material are rarely still. They jiggle back and forth in collective lattice vibrations known as phonons. Their motion can also carry a rotational element: In 2023, scientists at PSI…
Quantum entanglement breathes new life into decades-old physics test
Physicists at the BESIII Collaboration have breathed new life into a decades-old test of one of the Standard Model’s most important ideas, using a technique that had gone almost untouched by…
Hidden dark plasma zones produce unexpected bursts of reactive oxygen
Scientists from Tokyo Metropolitan University have found a way to make plasma more effective for its wide-ranging uses, from antimicrobial applications to surface conditioning in the semiconductor…
Scientists Close In on First-Ever Glimpse of Quantum Vacuum
Quantum theory says a vacuum isn’t truly empty, but proving it directly has remained out of reach. A new experiment using immensely powerful lasers could finally expose its hidden structure – and…
