Date Time New technology to improve worlds most sensitive scientific instruments A new technology that can improve gravitational-wave detectors, one of the most sensitive instruments used by scientific researchers, has been pioneered by physicists at The University of Western Australia in collaboration with an international team of researchers. The new technology allows the world’s existing gravitational wave detectors to achieve a sensitivity that was previously thought only to be achievable by building much bigger detectors. The paper, published in Communications Physics, was led by the A...

Simulation of non-Hermitian quantum mechanics using a quantum computer goes beyond centuries old conventions

In 2017, astronomers witnessed the birth of a black hole for the first time. Gravitational wave detectors picked up the ripples in spacetime caused by two neutron stars colliding to form the black hole, and other telescopes then observed the resulting explosion. But the real nitty-gritty of how the black hole formed, the movements of matter in the instants before it was sealed away inside the black hole’s event horizon, went unobserved. That’s because the gravitational waves thrown off in these final moments had such a high frequency that our current detectors can’t pick them up. If you...

Credit: Osaka University Osaka, Japan -- Though it sounds like something straight out of science fiction, controlling the speed of light has in fact been a long-standing challenge for physicists. In a study recently published in Communications Physics, researchers from Osaka University generated light bullets with highly controllable velocities. According to Albert Einstein's principle of relativity, the speed of light is constant and cannot be exceeded; however, it is possible to control the group velocity of optical pulses. Currently, the spatiotemporal coupling of optical pulses provides...
