MIT researchers have developed a new fabrication method that could enable the production of more energy efficient electronics by stacking multiple functional components on top of one existing circuit. In traditional circuits, logic devices that perform computation, like transistors, and memory devices that store data are built as separate components, forcing data to travel back and forth between them, which wastes energy. This new electronics integration platform allows scien

Researchers at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) have partnered with NTNU, the Norwegian University of Science and Technology in Trondheim, and the Institute of Nuclear Physics in the Polish Academy of Sciences to develop a method that facilitates the manufacture of particularly efficient magnetic nanomaterials in a relatively simple process based on inexpensive raw materials. Using a highly focused ion beam, they imprint magnetic nanostrips consisting of tiny,

Using proteins from a common tobacco plant virus, McGill chemistry researchers have developed a simple, eco-friendly way to arrange gold nanoparticles into ultrathin sheets, strengthening the particles’ optical properties. The result: cheaper, safer materials for solar panels, sensors and advanced optical devices. Gold nanoparticles are only effective in strengthening optical signals when the nanoparticles are arranged on a surface and spaced at exact distances. Until now, cr

In collaboration with scientists in Germany, EPFL researchers have demonstrated that the spiral geometry of tiny, twisted magnetic tubes can be leveraged to transmit data based on quasiparticles called magnons, rather than electrons.

When ice melts into water, it happens quickly, with the transition from solid to liquid being immediate. However, very thin materials do not adhere to these rules. Instead, an unusual state between solid and liquid arises: the hexatic phase. Researchers at the University of Vienna have now succeeded in directly observing this exotic phase in an atomically thin crystal. Using state-of-the-art electron microscopy and neural networks, they filmed a silver iodide crystal protecte

A team from the Faculty of Physics and the Centre for Quantum Optical Technologies at the Centre of New Technologies, University of Warsaw has developed a new method for measuring elusive terahertz signals using a "quantum antenna." The authors of the work utilized a novel setup for radio wave detection with Rydberg atoms to not only detect but also precisely calibrate a so-called frequency comb in the terahertz band. This band was until recently a white spot in the electroma

One of the enigmas of life is emergence, when the whole becomes more than its parts. Flocks of birds can instantly change direction when a predator appears, guided not by a lead bird but by a collective intelligence that no single bird can possess on its own. Multitudes of molecules skitter chaotically in a cell, but certain ones find each other, interact, and give rise to sophisticated cellular structures and functions that could not have been predicted by studying the molec

Silver-based atomic switches that create stable electrical connections between individual molecules and electrodes have been developed by researchers from Japan, addressing a key challenge in wiring molecular electronics. The switch operates by forming and breaking silver atomic filaments when a voltage is applied and reversed, corresponding to the “on” and “off” states. This method enables the scalable integration of molecular components, paving the way for ultra-compact and

By measuring the spin dynamics over a broad energy range with neutron spectroscopy on a single crystal, the team identified a large band splitting of about 60 millielectronvolts (meV) between two magnon branches, a 3 meV anisotropy gap in the lower branch, and an avoided crossing near 75 meV in the upper branch. The researchers were then able to reproduce these important features quantitatively using theoretical calculations based on spin-wave theory.

To visualize a quantum well, imagine a marble rolling in a groove between two raised edges. The marble can only move back and forth. A quantum well controls electrical current in a similar way, confining it in an ultrathin layer of material. This confinement improves how quickly you can encode information in light. The new paper shows how to make these wells work even better, whether for quicker downloads and smoother online experiences or for better qubits and more efficient

It is something like the “Holy Grail” of physics: unifying particle physics and gravitation. The world of tiny particles is described extremely well by quantum theory, while the world of gravitation is captured by Einstein’s general theory of relativity. But combining the two has not yet worked – the two leading theories of theoretical physics still do not quite fit together. There are many ideas for such a unification – with names like string theory, loop quantum gravity, ca

With carefully designed tunable active sites, unique structure of new single atom platforms enables strong gas binding in pioneering step towards more efficient industrially-relevant catalysis.
