A Century-Old Physics Effect Just Got a New Dimension
4+ hour, 35+ min ago (417+ words) Physicists have uncovered an in-plane Hall response that overturns a century-old assumption about how this famous electrical effect works. The discovery could eventually make multidirectional magnetic sensing possible with one tiny device....
Graphene Flakes Supercharge Liquid Crystal Optics in the Infrared
6+ hour, 27+ min ago (86+ words) A pinch of graphene may be all it takes to make liquid crystals dramatically more useful in the infrared. Researchers in Japan have shown that dispersing tiny flakes of the one-atom-thick carbon material into a common nematic liquid crystal boosts…...
Scientists just cracked the quantum code hidden in a single atom
12+ hour, 33+ min ago (850+ words) To build a large-scale quantum computer that works, scientists and engineers need to overcome the spontaneous errors that quantum bits, or qubits, create as they operate. Scientists encode these building blocks of quantum information to suppress errors in other qubits…...
Researchers Optimise Penning Traps For Single-Electron Qubits
1+ day, 10+ hour ago (877+ words) Millimetre-scale Penning traps previously relied upon approximations becoming inaccurate as device dimensions shrink. Now, an analytical solution offers precise design choices for optimising planar Penning trap geometry and voltage settings at sub-millimetre scales. This advancement minimises unwanted distortions in confining…...
Physicists Observe Hall Effect in Trion Fluids Within Electron–Hole
10+ hour, 8+ min ago (668+ words) A long-predicted quirk of quantum materials has finally been caught in action. In an elegant set of experiments described in Nature Physics, researchers report the first demonstration of the Hall effect in a trion fluid, a charged three-particle state that…...
Scientists Watch Light Supercharge Hydrogen Reactions on Platinum, Atom by
23+ hour, 43+ min ago (873+ words) In a result that could reshape how chemists think about catalysis, researchers have now achieved something once thought beyond the reach of experimental science: watching, at the nanometer scale, how light-driven collective electron oscillations known as plasmons help break apart…...
Scientists Learn to Stack Fano Interferences for Sharper Plasmonic Energy
23+ hour, 51+ min ago (73+ words) Light passing through a carefully engineered nanostructure can behave in ways that ordinary optics never allows. It can cancel itself out at certain frequencies, reinforce itself at others, and produce sharply asymmetric spectral lines that seem to defy the smooth,…...
Tailor-made nanopores: Vienna team shapes "white graphene" at the atomic scale
1+ day, 22+ hour ago (630+ words) A simulated microscopic image of hexagonal boron nitride with a circular pore surrounded by triangular pores. Darker circles represent individual boron atoms, whilst lighter circles represent nitrogen atoms....
Light Sparks New Material State in 30 Femtoseconds
2+ day, 2+ hour ago (514+ words) The properties of a material depend not only on how its atoms are arranged, but also on how its electrons are arranged and move. So what happens inside a material when light changes its properties? Previous studies have often examined…...
Photonic Structures in Nature and Bio-Mimetic Materials
2+ day, 3+ hour ago (35+ words) AIP Publishing LLC Topics covered include, but are not limited to: - Functional materials mimicking the optical properties of natural systems - Applications in sensing, displays, communication, and energy harvesting...
