Physicists at the University of Vienna have discovered magnons with lifespans that are one hundred times longer. Magnons are tiny waves of magnetization that move through solid magnetic materials, similar to ripples spreading across water after a stone falls in. Unlike photons, which can move through empty space or optical fibers, magnons travel inside magnetic [...]

Quantum physicists have uncovered a bizarre phenomenon in which photons appear to spend a “negative” amount of time interacting with atoms before emerging from a cloud of matter. As Homer tells us, Odysseus made an epic journey, against the odds, from Troy to his home in Ithaca. He visited many lands but mostly dwelt with [...]

A new experiment confirms that photons passing through a cloud of atoms can spend a negative amount of time there, and the atoms themselves are the ones saying so.

Researchers discovered that atomic rotations inside a crystal can unexpectedly flip direction while still obeying the laws of angular momentum conservation. An international team of researchers, including scientists from the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) and the Fritz Haber Institute of the Max Planck Society, has directly observed for the first time how angular momentum moves and…

Cutting-edge atomic clocks may soon reveal a strange possibility: time itself behaving like a quantum object, existing in multiple states at once. Few ideas in physics feel as intuitive, yet remain as puzzling, as time. In Einstein’s theory of relativity, time is not fixed. It changes depending on motion and gravity. When this concept is [...]

A new study links the universe’s expansion to quantum topology, suggesting that hidden mathematical structures may stabilize the cosmological constant in ways previously unrecognized. The cosmological constant is a term physicists use to describe the energy pushing the universe to expand faster over time. Despite its simple definition, it represents one of the deepest unsolved [...]

A subtle mechanical adjustment reveals a powerful way to control the quantum behavior of embedded defects. Researchers have identified a new method to control the quantum behavior of tiny imperfections in diamond by gently stretching or compressing the crystal.

A newly uncovered property of light suggests it may be far more self-sufficient than previously believed. Researchers at the University of East Anglia have identified a previously unknown property of light that allows it to twist, spin, and behave in unusual ways – without the need for mirrors, materials, or specialized lenses. In a finding [...]
