HEAs […]

A high order for a low dimension

IMAGE: Subtle changes in the arrangement of component materials can have a stronger knock-on effect to the bulk material than was previously thought. view more  Credit: © 2020 Kondo et al Spintronics refers to a suite of physical systems which may one day replace many electronic systems. To realize this generational leap, material components that confine […]

Stretching diamond for next-generation microelectronics

This work may lead to carbon-based electronic devices that require fewer toxic materials or harsh […]

Quantum wave in helium dimer filmed for the first time

Anyone entering the world of quantum physics must prepare themself for quite a few things unknown in the everyday world: Noble gases form compounds, atoms behave like particles and waves at the same time and events that in the macroscopic world exclude each other occur simultaneously. In the world of quantum physics, Reinhard Dörner and […]

Atomic-scale nanowires can now be produced at scale

Surrey helps to produce the world’s first neutron-rich, radioactive tantalum ions

An international team of scientists have unveiled the world’s first production of a purified beam of neutron-rich, radioactive tantalum ions. This development could now allow for lab-based experiments on exploding stars helping scientists to answer long-held questions such as “where does gold come from?” In a paper published in Physical Review Letters, the University of […]

Timekeeping theory combines quantum clocks and Einstein’s relativity

IMAGE: Quantum mechanics allows for a clock to move as if it were simultaneously traveling at two different speeds. New research finds that this leads to a correction in atomic clocks… view more  Credit: Petra Korlevic HANOVER, N.H. – October 23, 2020 – A phenomenon of quantum mechanics known as superposition can impact timekeeping in high-precision […]
