Researchers from the HSE International Laboratory for Supercomputer Atomistic Modelling and Multi-scale Analysis, JIHT RAS and MIPT have compared the performance of popular molecular modelling programs on GPU accelerators produced by AMD and Nvidia. In a paper published by the International Journal of High Performance Computing Applications, the scholars ported LAMMPS on the new open-source GPU technology, AMD HIP, for the first time.
The ability to turn on and off a physical process with just one photon is a fundamental building block for quantum photonic technologies. Realizing this in a chip-scale architecture is important for scalability, which amplifies a breakthrough by CCNY researchers led by physicist Vinod Menon. They've demonstrated for the first time the use of "Rydberg states" in solid state materials (previously shown in cold atom gases) to enhance nonlinear optical interactions to unprecedented levels in solid state systems.
Researchers at the University of California, Riverside, have used a nanoscale synthetic antiferromagnet to control the interaction between magnons -- research that could lead to faster and more energy-efficient computers.
Scientists planning the Interstellar Probe mission, which will travel 1,000 AU from the sun, roughly 10 times as far as the Voyager spacecraft, will discuss the mission at the European Geosciences Union General Assembly 2021, which is taking place from 19-30 April 2021.
Quantum systems consisting of several particles can be used to measure magnetic or electric fields more precisely. A young physicist at the University of Basel has now proposed a new scheme for such measurements that uses a particular kind of correlation between quantum particles.
In new research appearing in the Journal of Physical Chemistry Letters, Scott Sayres and his research group describe their investigations into the molecular dynamics of titania clusters. Such research is a basic step toward the development of more efficient photocatalysts.
Two-dimensional (2D) materials with a single-layer thickness retaining magnetic order in atomically thin limit began to increase their scientific and technological significance after the successful synthesis of graphene and later investigations of van der Waals materials. CrBr3 has been known since the 60s as a van der Waals ferromagnet.
Researchers at Singapore-MIT Alliance for Research and Technology (SMART) and National University of Singapore (NUS) have discovered a new way to control light emission from materials. While recent discoveries focused on manipulation of atomically-thin 2D materials, the new breakthrough can be used to stack technologically-relevant 3D materials at a twist angle. The discovery can be significant for applications in medicine, environmental or information technologies.
The 'stickiness', or viscosity, of microscopic liquids can now be measured thousands of times faster than ever before, potentially leading to better understanding of living cells, disease diagnostics and pharmaceutical testing.
Scientists at Sanford Burnham Prebys have identified, at an atomic level, how a part of a protein called PLEKHA7 interacts with a cell's membrane to regulate important intercellular communications. The research, published in the journal Structure, points to hotspots within PLEKHA7 as targets for drugs. These targets could be key in designing treatments for advanced colon, breast and ovarian cancers.
