Magnon lifetime extended 100x paves the way for mini quantum computers
Magnons are tiny waves in magnetization that travel through solid magnetic materials, much like the ripples that spread across a pond when a stone is thrown into it. Unlike photons, which travel through empty space or optical ...

Symmetry says these crystal vibrations can never mix, but an exotic quantum phase rewrites the rules
Symmetry is one of the most fundamental principles in nature. It describes the rules that make an object look unchanged after a rotation, reflection, or other transformations. In materials, symmetry governs how atoms and ...

Physicists have measured 'negative time' in the lab
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 the nymph Calypso on her island. We can imagine that his wife, Penelope, would ...

Frozen-in gravity: A new way to understand the evolution of spacetime dynamics
The concept of spacetime, first described in Einstein's theory of general relativity, has since been widely studied by many physicists worldwide. Spacetime is described mathematically as a four-dimensional (4D) continuum ...
Sudden quantum jolts may not break adiabatic behavior after all
In thermodynamics, an "adiabatic process" is a system change that transfers no heat in or out of the system. Any and all energy change in that system are therefore accomplished by doing work on the system, work being action ...
Room-temperature multiferroic could pave way to low-energy computing
A team of researchers at Rice University has engineered a new version of a well-known multiferroic that exhibits orders of magnitude higher performance at room temperature than its parent material. The study, published in ...

A longstanding quantum roadblock just fell, opening existing fiber networks to ultra-secure light signals
Researchers at the Niels Bohr Institute have broken a longstanding barrier by managing to send single photons—that can't be copied or split and thus are secure—in the network of optical fibers we already have. This opens ...
