Quantum leap for speed limit bounds

Nature's speed limits aren't posted on road signs, but Rice University physicists have discovered a new way to deduce them that is better—infinitely better, in some cases—than previous methods.

Unlocking deep carbon's fate

CO2 in the deep Earth may be more active than previously thought and may have played a bigger role in climate change than scientists knew before, according to a study by the Hong Kong University of Science and Technology ...

Greater insight into the pinning effects of skyrmions

When researchers use an optical Kerr microscope to zoom in on thin films of magnetic material, given the right conditions, they observe a sort of micro-scale magnetic hurricane. Physicists call these whirlwind-like magnetic ...

Three-channel Kondo effect discovered in cubic holmium compound

A scientist from Tokyo Metropolitan University has applied numerical methods to capture the hallmarks of a quantum phenomenon known as the three-channel Kondo effect in an f-electron system for the first time. Professor Takashi ...

Oscillating quasiparticles: the cycle of decay and rebirth

Decay is relentless in the macroscopic world: Broken objects do not fit themselves back together again. However, other laws are valid in the quantum world: New research shows that so-called quasiparticles can decay and reorganize ...
