Scientists from the Theory Department of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science (CFEL) in Hamburg, Germany have shown through theoretical calculations and computer simulations that the force between electrons and lattice distortions in an atomically thin two-dimensional superconductor can be controlled with

Why does quantum mechanics work so well for microscopic objects, yet macroscopic objects are described by classical physics? This question has bothered physicists since the development of quantum theory more than 100 years ago. Researchers at Delft University of Technology and the University of Vienna have now devised a macroscopic system that exhibits entanglement between

By essentially turning down the pitch of sound waves, University of Michigan engineering researchers have devised a way to unlock greater amounts of data from acoustic fields than ever before. That additional information could boost performance of passive sonar and echolocation systems for detecting and tracking adversaries in the ocean, medical imaging devices, seismic surveying

USC scientists have demonstrated a theoretical method to enhance the performance of quantum computers, an important step to scale a technology with potential to solve some of society’s biggest challenges. The method addresses a weakness that bedevils performance of the next-generation computers by suppressing erroneous calculations while increasing fidelity of results, a critical step before

When tiny particles strike a metal surface at high speed—for example, as coatings being sprayed or as micrometeorites pummeling a space station—the moment of impact happens so fast that the details of process haven’t been clearly understood, until now. A team of researchers at MIT has just accomplished the first detailed high-speed imaging and analysis

Scientists from the Max Born Institute (MBI) have developed the first refractive lens that focuses extreme ultraviolet beams. Instead of using a glass lens, which is non-transparent in the extreme-ultraviolet region, the researchers have demonstrated a lens that is formed by a jet of atoms. The results, which provide novel opportunities for the imaging of

Experimental atomic clocks at the National Institute of Standards and Technology (NIST) have achieved three new performance records, now ticking precisely enough to not only improve timekeeping and navigation, but also detect faint signals from gravity, the early universe and perhaps even dark matter. The clocks each trap a thousand ytterbium atoms in optical lattices,

Complex systems theory is usually used to study things like the immune system, global climate, ecosystems, transportation or communications systems. But with global politics becoming more unpredictable—highlighted by the UK’s vote for Brexit and the presidential elections of Donald Trump in the USA and Jair Bolsonaro in Brazil—it is being used to examine the stability

Electrical engineers in the accelerator physics group at TU Darmstadt have developed a design for a laser-driven electron accelerator so small it could be produced on a silicon chip. It would be inexpensive and with multiple applications. The design, which has been published in Physical Review Letters, is now being realised as part of an

Credit: Nature, DOI: 10.1038/s41586-018-0695-9 Scientists have discovered that semiconducting molecules with unpaired electrons, termed ‘radicals’ can be used to fabricate very efficient organic-light-emitting diodes (OLEDs), exploiting
