Tiny quantum electronic vortexes can circulate in superconductors in ways not seen before
Within superconductors little tornadoes of electrons, known as quantum vortices, can occur which have important implications in superconducting applications such as quantum sensors. Now a new kind of superconducting vortex has been found, an internat.....»»
New study explains interaction between quantized vortices and normal fluids
Osaka Metropolitan University scientists investigated numerically the interaction between a quantized vortex and a normal fluid. Based on the experimental results, researchers decided the most consistent of several theoretical models. They found that.....»»
Symmetry breaking by ultrashort light pulses opens new quantum pathways for coherent phonons
Atoms in a crystal form a regular lattice, in which they can move over small distances from their equilibrium positions. Such phonon excitations are represented by quantum states. A superposition of phonon states defines a so-called phonon wavepacket.....»»

Progressive quantum leaps—high-speed, thin-film lithium niobate quantum processors driven by quantum emitters
Scalable photonic quantum computing architectures require photonic processing devices. Such platforms rely on low-loss, high-speed, reconfigurable circuits and near-deterministic resource state generators. In a new report now published in Science Adv.....»»
Designing synthetic receptors for precise cell control
Biosensors are artificial molecular complexes designed to detect the presence of target chemicals or even biomolecules. Consequently, biosensors have become important in diagnostics and synthetic cell biology. However, typical methods for engineering.....»»
Demystifying vortex rings in nuclear fusion and supernovae
Better understanding the formation of swirling, ring-shaped disturbances—known as vortex rings—could help nuclear fusion researchers compress fuel more efficiently, bringing it closer to becoming a viable energy source......»»
Perfection: The enemy of evolution
Scientists are often trained to seek out the absolute best solution to a given problem. On a chalk board, this might look something like drawing a graph to find a function's minimum or maximum point. When designing a turbojet engine, it might mean tw.....»»
Researchers use structured light on a chip in another photonics breakthrough
In everyday life we experience light in one of its simplest forms—optical rays or beams. However, light can exist in much more exotic forms. Thus, even beams can be shaped to take the form of spirals; so-called vortex beams, endowed with unusual pr.....»»
A spontaneous topological Hall effect driven by a non-coplanar antiferromagnetic order in van der Waals materials
Ferromagnets are materials that become magnetized and remain so while they are exposed to an external magnetic field. In these materials, electric currents typically induce a so-called transverse Hall voltage (i.e., a voltage resulting from the defle.....»»
Musk says Tesla building two new models, probably challenged by the economy in next 12 months
Tesla held its annual shareholder meeting in Texas, USA, on May 16. CEO Elon Musk said the company is designing two new vehicle models. He also warned that Tesla will likely see challenges brought by the global economic environment in the coming mont.....»»
Tai-Saw upbeat about shipments for automotive, networking
Tai-Saw Technology, a Taiwan-based supplier of SAW (surface acoustic wave) filters and quartz crystal components, anticipates an improvement in total production utilization in the second quarter as shipments for automotive and networking device appli.....»»
Designing 3D-printed pills with desired drug release
Don't be surprised to see pills with unusual shapes in the future. At first sight they may look funny, but they can release pharmaceuticals inside the body in a controlled manner. Using a combination of advanced computational methods and 3D printing,.....»»
Researchers develop solution-processible single-crystal porous organic polymer
Synthetic organic polymers are typically insoluble polycrystalline or amorphous products rather than single crystals. The direct synthesis of single-crystal porous polymers remains a challenge in polymer science and crystal engineering......»»
Designing cameras for harsh environments? Be sure to account for lens mount details
