Understanding gravity in the framework of quantum mechanics is one of the great challenges in modern physics. Along this line, a prime question is to find whether gravity is a quantum entity subject to the rules of quantum mechanics. It is fair to say that there are no feasible ideas yet to test the quantum coherent behaviour of gravity directly in a laboratory experiment. In a recent paper, Gavin Morley and colleagues introduce an idea for such a test based on the principle that two objects cannot be entangled without a quantum mediator.
Dan Bayliss, lead author of the research, commented: "The discovery of NGTS-1b was a complete surprise to us - such massive planets were not thought to exist around such small stars. This is the first exoplanet we have found with our new NGTS facility and we are already challenging the received wisdom of how planets form."
Peter Wheatley added, “Having worked for almost a decade to develop NGTS, it is thrilling to see it picking out new and unexpected types of planets."
Gold’s origin in the Universe has finally been confirmed, after a gravitational wave source was seen and heard for the first time ever by an international collaboration of researchers, with astronomers at the University of Warwick playing a leading role.
Direct bandgap photoluminescence in the 3–5 um wavelength window is demonstrated from GeSn microdisks, suggesting that GeSn alloys are well suited for mid-infrared integrated gas sensors on Si chips.
