Hot on the heels of proving an 87-year-old prediction that matter can be generated directly from light, Rice University physicists and their colleagues have detailed how that process may impact future studies of primordial plasma […]
Spin waves, or magnons, as the elementary excitation of the magnetic system, can transfer spin angular momentum, which provides wide prospects for the Non-volatile, low-energy-consumption, high-speed and small-size microelectronic devices in the post-Moore period. Magnonics, […]
Researchers from the University of Science and Technology of China (USTC) of the Chinese Academy of Sciences, together with international collaborators, observed an obvious enhancement in the yield ratio between strange (Ds±) and nonstrange (D0) […]
Smartphones, notebooks and other electronic devices of our everyday life strongly benefit from the ever-increasing miniaturization of semiconductor devices. This development comes however at a price: confining electrons enhances their scattering– cell phones heat up. […]
In a new report now published on Science Advances, Tiancheng Song and a research team at the department of physics, University of Washington, U.S., and materials and nanoarchitectronics in Japan and China, detailed spin photovoltaic […]
Similar to a magnet that always has both south and north poles, a kind of special quasiparticles in condensed matter called “Weyl Fermions” always appear in pairs with opposite chirality. There had been no experimental […]
Scientists have generated circularly polarized light and controlled its direction without using clunky magnets or very low temperatures. The findings, by Nagoya University researchers and colleagues in Japan, and published in the journal Advanced Materials, […]
The next generation of computing and information processing lies in the intriguing world of quantum mechanics. Quantum computers are expected to be capable of solving large, extremely complex problems that are beyond the capacity of […]
The S-matrix bootstrap is a numerical method that can be used to determine or constrain the scattering amplitudes of particles in quantum field theory using simple principles. Over the past few decades, some physicists have […]
