Extracting information about dynamic processes in the picosecond (ps) requires extensive modification and optimal control of the operation conditions. This research, published in Ultramicroscopy surpasses these shortcomings by combining a delay line detector with continuous illumination in a transmission electron microscope.

Emory studying mind-body interventions for trauma-related dissociation Emory University is part of a $3.8 million grant from the NIH’s National Center for Complementary and Integrative Health awarded to both Emory and University of Pittsburgh. The funding will support a clinical trial to test the mechanisms of new mind-body interventions for trauma-related dissociation. Dissociation is a disconnection between a person’s thoughts, memories, feelings, actions or sense of who he or she is.  E...

Credit: Osaka University Osaka, Japan --Straight-line constant-speed propagation in free space is a basic characteristic of light. In a recent study published in Communications Physics, researchers from Osaka University discovered the phenomenon of reciprocating propagation of laser pulse intensity in free space. Spatiotemporal couplings have been recently used to produce light with tunable group-velocity, direction, and trajectory in free space. For example, the flying focus (a moving laser p...

Share Aalto researchers have used an IBM quantum computer to explore an overlooked area of physics, and have challenged 100 year old cherished notions about information at the quantum level. The rules of quantum physics – which govern how very small things behave – use mathematical operators called Hermitian Hamiltonians. Hermitian operators have underpinned quantum physics for nearly 100 years but recently, theorists have realized that it is possible to extend its fundamental equations to ...

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...

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 t...

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 Einsteins principle of relativity, the speed of light is constant and cannot be exceeded; however, it is possible to control the g...
