Researchers at the Georgia Institute of Technology have devised a method for using an origami-based structure to create radio frequency filters that have adjustable dimensions, enabling the devices to change which signals they block throughout a large range of frequencies.
A team at the HZB has improved the manufacturing process of photocathodes and can now provide photocathodes with high quantum efficiency for bERLinPro.
Research teams from UNSW are investigating multiple pathways to scale up atom-based computing architectures using spin-orbit coupling -- advancing towards their goal of building a silicon-based quantum computer in Australia.
A team of international researchers led by engineers from the National University of Singapore (NUS) have invented a new magnetic device which is able to manipulate digital information 20 times more efficiently and with 10 times more stability than commercial spintronic digital memories. The novel spintronic memory device employs ferrimagnets and was developed in collaboration with researchers from Toyota Technological Institute, Nagoya, and Korea University, Seoul.
Scientists have, for the first time, observed a square lattice of merons and antimerons -- tiny magnetic vortices and antivortices that form in a thin plate of the helical magnet Co8Zn9Mn3. The ability to manipulate nanometer-scale spin textures such as merons and skyrmions is a key to the development of spintronics -- next-generation electronic devices that are very low in power consumption.
Researchers at Osaka University observe a magnetic reconnection driven by electron dynamics in laser-produced plasmas. Magnetic reconnections are often observed in the magnetic flux on the Sun and the Earth's magnetosphere. It has been highly challenging to reveal the electron scale, microscopic information in the vast universe. Applying a weak magnetic field, where only electrons are directly coupled with the magnetic field, we observed a plasmoid and cusp-like features typical to magnetic reconnections.
USC scientists have demonstrated a theoretical method to enhance the performance of quantum computers works, an important step to scale the transformative technology.
Theoretical physics discovery paves the way for future technological applications. Study led by young Brazilian researcher featured on cover of Physical Review Letters.
A research team from ITMO University and the University of Rochester (the USA) conducted a study on the formation of terahertz radiation in liquids. Previously, the generation of such radiation in a liquid medium was considered impossible due to high absorption. However, in their new research, the scientists described this phenomenon's physical nature and demonstrated that liquid radiation sources can be equally effective to traditional ones. The results have been published in Applied Physics Letters.
Earlier this year researchers developed sensing protocols that allow optical fibers to 'listen' outside an optical fiber where they cannot 'look', based on an interplay between light waves and ultrasound. Now they have constructed a measurement protocol that can map local power levels of multiple optical wave components over many kilometers of fiber. This new insight may be applied to sensor systems of longer reach, higher spatial resolution, and better precision.
