Hydride research pushes frontiers of practical, accessible superconductivity

29 avril

Science is taking a step forward in the quest for superconductors that will not require ultra-high pressure to function, thanks to multinational research led by Xiaojia Chen at the University of Houston.

Quantum challenge to be solved one mile underground

29 avril

Radiation from space is a challenge for quantum computers as their computation time becomes limited by cosmic rays. Researchers from Chalmers University of Technology, Sweden, and University of Waterloo in Canada are now going deep underground in the search for a solution to this problem—in a (…)

New tech enables deep tissue imaging during surgery

29 avril

Hyperspectral imaging (HSI) is a state-of-the-art technique that captures and processes information across a given electromagnetic spectrum. Unlike traditional imaging techniques that capture light intensity at specific wavelengths, HSI collects a full spectrum at each pixel in an image. This (…)

Researchers discover ’topological Kerr effect’ in two-dimensional quantum magnets

29 avril

In a recent collaboration between the High Magnetic Field Center of the Hefei Institutes of Physical Science of Chinese Academy of Sciences, and the University of Science and Technology of China, researchers introduced the concept of the topological Kerr effect (TKE) by utilizing the (…)

Physicists overcome two key operating hurdles in fusion reactions

29 avril

A team of physicists from several institutions across the U.S. working with a colleague from China, at the DIII-D National Fusion Facility, in San Diego, California, has devised a way to overcome two key hurdles standing in the way of using fusion as a general power source.

When does a conductor not conduct ? Switching a 2D metal-organic framework from an insulator to a metal

29 avril

An Australian-led study has found unusual insulating behavior in a new atomically-thin material—and the ability to switch it on and off.

Topologically controlled multiskyrmions : Researchers propose a new family of quasiparticles

29 avril

Skyrmions are topologically protected quasiparticles with sophisticated spin textures, widely studied in condensed-matter systems, magnets and recently in photonics, which predicts great potential in ultra-high-capacity information storage, due to their diversified and stable topological spin (…)

Optical barcodes expand range of high-resolution sensor

26 avril

The same geometric quirk that lets visitors murmur messages around the circular dome of the whispering gallery at St. Paul’s Cathedral in London or across St. Louis Union Station’s whispering arch also enables the construction of high-resolution optical sensors. Whispering-gallery-mode (WGM) (…)

The end of the quantum tunnel : Exact instanton transseries for quantum mechanics

26 avril

In the quantum world, processes can be separated into two distinct classes. One class, that of the so-called "perturbative" phenomena, is relatively easy to detect, both in an experiment and in a mathematical computation. Examples are plentiful : the light that atoms emit, the energy (…)

Enhanced superconductivity in monolayer FeSe films on SrTiO&#8323 ;(001) via metallic δ-doping

26 avril

Interface engineering has been proven to be effective in discovering new quantum states, such as topological states, superconductivity, charge density waves, magnetism, etc., which require atomic-scale heterostructure fabrication. Monolayer FeSe on SrTiO3 substrates has attracted intense (…)
