A step towards quantum gravity In Einstein's theory of general relativity, gravity arises when a massive object distorts the fabric of spacetime the way a ball sinks into a piece of stretched cloth. Solving Einstein's equ …
China claims new world record for strongest steady magnetic field On August 12, the hybrid magnet of the Steady High Magnetic Field Facility (SHMFF) in Hefei, China, produced a steady field of 45.22 tesla (T), the highest steady magnetic field by a working magnet in …
Ultracold atoms dressed by light simulate gauge theories Our modern understanding of the physical world is based on gauge theories: mathematical models from theoretical physics that describe the interactions between elementary particles (such as electrons o …
Higgs10: Inventing the future of Higgs research In 1975, three CERN theorists, John Ellis, Mary K. Gaillard and Dimitri Nanopoulos, undertook the first comprehensive study of the collider phenomenology of the Higgs boson. Almost 40 years later, it …
Scientists twirl liquid light into time-periodic cluster Researchers from Skoltech, the University of Iceland, and the University of Southampton have demonstrated the formation of an odd never-before-seen entity from the realm of quantum physics: a cluster …
Customized fiber generates Bessel beams An all fiber-based approach to generating special optical beams, called Bessel beams, could open up new applications in imaging, optical trapping and communications.
Perovskite: New LED technology surpasses the lifetime milestone Perovskite LEDs are an emerging technology for next-generation display, lighting and communications. While perovskite LEDs can be produced simply and at low cost, they show clear technological advanta …
Robotic motion in curved space defies standard laws of physics When humans, animals, and machines move throughout the world, they always push against something, whether it's the ground, air, or water. Until recently, physicists believed this to be a constant …
Machine learning reveals hidden components of X-ray pulses Ultrafast pulses from X-ray lasers reveal how atoms move at timescales of a femtosecond. That's a quadrillionth of a second. However, measuring the properties of the pulses themselves is challeng …
Do 'bouncing universes' have a beginning? In trying to understand the nature of the cosmos, some theorists propose that the universe expands and contracts in endless cycles.
Simultaneous multi-gas detection needs only sub-μL analyte Trace gas detection based on laser absorption spectroscopy (LAS) is a powerful technique due to its high sensitivity and selectivity, and it is widely used in many fields. Most of current works are pe …
