Quantum effect triggers unusual material expansion

You know how you leave space in a water bottle before you pop it in the freezer—to accommodate the fact that water expands as it freezes? Most metal parts in airplanes face the more common opposite problem. At high altitudes ...

Novel quantum effect found: Spin-rotation coupling

Imagine a dancer en pointe, spinning on her own axis while dancing on a rotating carousel. She might injure herself when both rotations add up and the angular momentum is transferred. Are similar phenomena also present in ...

Quantum technologies: New insights into superconducting processes

The development of a quantum computer that can solve problems, which classical computers can only solve with great effort or not at all—this is the goal currently being pursued by an ever-growing number of research teams ...

Quantum fluctuations sustain the record superconductor

Calculations performed by an international team of researchers from Spain, Italy, France, Germany, and Japan show that the crystal structure of the record superconducting LaH10 compound is stabilized by atomic quantum fluctuations. ...

Liquid flow is influenced by a quantum effect in water

Researchers at EPFL have discovered that the viscosity of solutions of electrically charged polymers dissolved in water is influenced by a quantum effect. This tiny quantum effect influences the way water molecules interact ...
