Researchers have observed the ‘fingerprint’ of a mysterious new quantum state of matter in a two-dimensional material, in which electrons break apart.
Researchers have found that quantum effects are the reason that hydrogen sulphide – which has the distinct smell of rotten eggs –behaves as a superconductor at record-breaking temperatures, which may aid in the search for room temperature superconductors.
Professor Gilbert Lonzarich of the Physics department has been selected for the 2015 Kamerlingh Onnes prize, in recognition of his 'visionary experiments concerning the emergence of superconductivity for strongly renormalized quasiparticles at the edge of magnetic order'.
Scientists have successfully demonstrated a new way to control the “spin” of an electron – the natural intrinsic angular momentum of electrons which could underpin faster computing in the future. The technique counterintuitively makes use of the ever-changing magnetic field of the electron’s environment - one of the main obstacles to traditional methods of spin control.
Breakthrough guarantees “unconditional” security of information by harnessing quantum theory and relativity, and has been successfully demonstrated on a global scale for the first time.
“Niels Bohr once said that those who are not shocked when they first come across quantum theory cannot possibly have understood it,” Professor Mark Warner tells his audience of A-Level physicists on the final day of the 2013 Senior Physics Challenge.
The realisation of quantum networks is one of the major challenges of modern physics. Now, new research shows how high-quality photons can be generated from ‘solid-state’ chips, bringing us closer to the quantum ‘Internet’.
