New form of matter ‘excitonium’ discovered Los Angeles | Scientists have proven the existence of new form of matter called excitonium – which was first theorised almost 50 years ago. Researchers from University of California Berkeley and University of Illinois at Urbana-Champaign in the US studied non-doped crystals of the transition metal dichalcogenide titanium diselenide (1T-TiSe2). Excitonium is a condensate – it exhibits macroscopic quantum phenomena, like a superconductor. It is made up of excitons, particles that are formed in a very strange quantum mechanical pairing, namely that of an…

Strange X-rays point to possible ‘dark’ matter

Strange X-rays point to possible ‘dark’ matter New observation increases the likelihood that this link to unseen matter is real, scientists say Strange : Artist’s rendering of NASA’s Earth-orbiting Chandra telescope against the backdrop of space. This craft has found an excess of X-rays. This bonus radiation may come from the decaying of particles of dark matter. An orbiting telescope has just spotted a strange X-ray signal. It’s raising hopes that the source may be dark matter. That’s the unknown — and unseen — substance that scientists believe constitutes most of the…
