The study could have applications in spintronics and quantum computing. It was conducted by an international collaboration and published in Nature. Its first author is a researcher at the University of São Paulo.
The new compact representation of fermions outperforms all previous representations improving memory use and algorithm size each by at least 25% - a significant step towards realising practical scientific applications on near-term quantum computers.
A researcher from the University of Tsukuba has introduced a new theory for superconductivity that can better explain the results of recent experiments with high-temperature superconductors. By focusing on the "Berry connection," this work may lead to energy distribution with much less electrical resistance.
Scientists have long used supercomputers to better understand how turbulent flows behave under a variety of conditions. Recognizing a need to include the complex but essential concept of "intermittency" in turbulent flows, researchers at CORIA and RWTH Aachen University used Jülich Supercomputing Centre's infrastructure to run highly detailed simulations.
An MIT study shows radioactive molecules are sensitive to subtle nuclear phenomena. The molecules might help physicists probe violation of the most fundamental symmetries of nature, including why the universe contains relatively little antimatter.
Scientists at KAIST have fabricated a laser system that generates highly interactive quantum particles at room temperature. Their findings, published in the journal Nature Photonics, could lead to a single microcavity laser system that requires lower threshold energy as its energy loss increases.
Researchers at ETH Zurich have succeeded in observing a crystal that consists only of electrons. Such Wigner crystals were already predicted almost ninety years ago but could only now be observed directly in a semiconductor material.
There is a significant discrepancy between theoretical and observed amounts of lithium in our universe. This is known as the cosmological lithium problem, and it has plagued cosmologists for decades. Now, researchers have reduced this discrepancy by around 10%, thanks to a new experiment on the nuclear processes responsible for the creation of lithium. This research could point the way to a more complete understanding of the early universe.
The new technology, enabling the storage of information in the thinnest unit known to science, is expected to improve future electronic devices in terms of density, speed, and efficiency. The allowed quantum-mechanical electron tunneling through the atomically thin film may boost the information reading process much beyond current technologies. The technology involves laterally sliding one-atom-thick layers of boron and nitrogen one over the other -- a new way to switch electric polarization on/off.
Recently, the Wang Danhong research group of Nankai University reviewed the latest progress of e-NRR catalysts under ambient conditions from the perspective of defect and interface engineering.
