Physicists show how to detect higher-order topological insulators

One-dimensional surface hinge states characteristic of HOTIs. Researchers have shown how to detect HOTIs without observing such hinge states. Credit: The Grainger College of Engineering at University of Illinois Urbana-Champaign…

Unlocking the magnetic superpowers of topological magnons

Forget about being clean, embrace mess

Within a dense system some terbium ions form pair states. Because of their unique properties, these pairs are blind to the single terbium ions nearby that would cause them to…

‘Sudden death’ of quantum fluctuations defies current theories of superconductivity

First direct imaging of tiny noble gas clusters at room temperature

Xenon nanocluster between two graphene layers, with sizes between two and ten atoms. Credit: Manuel Längle For the first time, a research team has succeeded in stabilizing and directly imaging…

Generating stable qubits at room temperature

Incorporating a chromophore in a metal-organic framework suppressed the molecular motion sufficiently to maintain the quantum coherence of the quintet state for more than 100 nanoseconds. Credit: Nobuhiro Yanai A…

Research offers insights into the metal-to-insulator transition without breaking symmetry

Credit: Yale University Metal-to-insulator transition—a process that turns materials from a conductor to an insulator—has been a crucial process behind microelectronic switches, nonvolatile memory, and neuromorphic computing materials. In many…

In novel quantum computer design, qubits use magnets to selectively communicate

Researchers have demonstrated that qubits (represented by the spheres and arrows) can “talk” to each other through a magnet (represented by the rectangular solid) rather than through air. This technology…
