ALBUQUERQUE, N.M. — Sandia’s Z machine has produced plasmas that exceed temperatures of 2 billion degrees Kelvin — hotter than the interiors of stars. The unexpectedly hot output, if its cause were ...

Q: Just as I understand the concept of color temperature (Kelvin), now CRI is being bandied about as LEDs come into the market. What is it exactly? A: I am right there with you. From the beginning of ...

David Reilly and his University of Sidney team developed a silicon chip that can control spin qubits at milli-kelvin temperatures. That’s just slightly above absolute zero (-273.15 degrees Celsius), ...

Warm and hot conditions are believed to destroy quantum effects. However, for the first time, a team of researchers has shown that quantum states can exist even at high temperatures. They created and ...

Cool stuff Interior view of the Pony cryostat installed at Argonne National Laboratory in February. The Pony provides scientific users with continuous sub-Kelvin cooling and a large experimental space ...

Can a solid — a material with a rigid, spatially ordered structure — also be a superfluid that flows with zero viscosity? Theoretical physicist Anthony Leggett posed this question in 1970 1. An ...
