Although most of the universe is made up of dark matter, very little is known about it. Physicists from Heinrich Heine University Düsseldorf (HHU) led by Prof. Stephan Schiller have used a high-precision experiment to look for interaction between dark matter and normal matter. They presented their findings in today's edition of the journal NATURE.
KAIST physicists described a route to design the energy-efficient generation, manipulation and detection of spin currents using nonmagnetic two-dimensional materials. The research team, led by Professor Sungjae Cho, observed highly efficient charge-to-spin interconversion via the gate-tunable Rashba-Edelstien effect (REE) in graphene heterostructures.
An international research team led by scientists at the University of California, Riverside, has observed light emission from a new type of transition between electronic valleys, known as intervalley transmissions. The research provides a new way to read out valley information, potentially leading to new types of devices.
Scientists have pioneered a new technique to expose hidden biochemical pathways involving single molecules at the nanoscale.
New research by scientists at the Dalian Institute of Chemical Physics (DICP) of the Chinese Academy of Sciences (CAS) has shown, surprisingly, in the simplest, well-studied reaction, there is still uncovered mechanism. It leads to clear quantum interference and verifies again that Nature does 'play dice.'
Hokkaido University scientists have fabricated a crystal that autonomously flips back and forth while changing its flipping patterns in response to lighting conditions.
The measurement of a strontium ion lasts barely a millionth of a second but the researchers have managed to make a 'film' of the process by reconstructing the quantum state of the system at different moments. The results confirm one of the most subtle predictions in quantum physics.
A new machine learning tool can calculate the energy required to make -- or break -- simple molecules with higher accuracy than conventional methods. Extensions to more complicated molecules may help reveal the inner workings of the chemical reactions that nourish the global ecosystem.
Quantum Spin Liquids are candidates for potential use in future information technologies. So far, Quantum Spin Liquids have usually only been found in one or two dimensional magnetic systems only. Now an international team led by HZB scientists has investigated crystals of PbCuTe2O6 with neutron experiments at ISIS, NIST and ILL.
Yvan Buggy and his co-workers at Heriot-Watt University in Edinburgh, Scotland, have developed a mathematical model of the flow of ultra-cold lsuperfluids, showing how they deform when they encounter impurities. This work is now published in EPJ D.
