• When does a conductor not conduct?

    Updated: 2024-04-29 14:30:39
    A new study uncovers a switchable, atomically-thin metal-organic material that could be used in future low-energy electronic technologies. The study shows that electron interactions in this material create an unusual electrically-insulating phase in which electrons are 'frozen'. By reducing the population of electrons, the authors are able to unfreeze the remaining electrons, allowing for controlled transitions between insulating and electrically-conductive phases: the key to the on-off binary operations of classical computing.

  • Physicists show that light can generate electricity even in translucent materials

    Updated: 2024-04-29 14:30:31
    Some materials are transparent to light of a certain frequency. When such light is shone on them, electrical currents can still be generated, contrary to previous assumptions. Scientists have managed to prove this.

  • From disorder to order: Flocking birds and 'spinning' particles

    Updated: 2024-04-26 20:52:06
    Researchers have demonstrated that ferromagnetism, an ordered state of atoms, can be induced by increasing particle motility and that repulsive forces between atoms are sufficient to maintain it. The discovery not only extends the concept of active matter to quantum systems but also contributes to the development of novel technologies that rely on the magnetic properties of particles, such as magnetic memory and quantum computing.

  • Tomography-based digital twins of Nd-Fe-B magnets

    Updated: 2024-04-26 20:52:01
    Scientists have succeeded in simulating the magnetization reversal of Nd-Fe-B magnets using large-scale finite element models constructed based on tomographic data obtained by electron microscopy. Such simulations have shed light on microstructural features that hinder the coercivity, which quantifies a magnet's resistance to demagnetization in opposing magnetic fields. New tomography-based models are expected to guide toward the development of sustainable permanent magnets with ultimate performance.

  • Violation of Bell’s inequality in Josephson phase qubits

    Updated: 2024-04-22 05:30:26
    Very cool…another step towards demonstrating that Josephson phase/flux systems can be treated as macroscopic coherent quantum objects. Violation of Bell’s inequality in Josephson phase qubits I was wondering if you could demonstrate this the other day! From Science Daily: The measurement of a Bell violation in a superconducting circuit was recently stated to be the […]

    Via The Quantum Pontiff: What an AWESOME idea for a conference! Coherence in Superconducting Qubits 2010 …I shouldn’t get so excited about these things, but, but… just look at the topic list! 😀 This conference will foster discussion and collaboration among investigators stimulating: * A fuller, more accurate understanding of the types of defects limiting […]

  • Funding and grant writing in Research

    Updated: 2024-04-22 05:30:25
    Via Swans on Tea: “Real Lives and White Lies in the Funding of Scientific Research” An excellent article explaining the problems faced by research groups, especially small ones, when a large portion of allocated researcher time is dedicated to writing grant proposals.

  • CMMP 2009

    Updated: 2024-04-22 05:30:24
    It’s that time again! The UK’s hottest low temperature conference…Condensed Matter and Materials Physics 2009. Venue: Warwick University. Why not join me for some unmissable Physics action – just click on the link above to sign up. I’ll hopefully by then have some form of poster with results from measurements on Ferromagnetic Josephson Junctions. By […]

  • Presentation on Quantum Computing to UKTA

    Updated: 2024-04-22 05:30:22
    I’m giving a talk in London on the 12th September to the UKTA (UK Transhumanist Association) for a regular event known as UKH+. There will be discussion sessions before and after the talk in a lovely nearby pub (The Marlborough Arms). The talk will be about quantum computing: What quantum computers can do, and more […]

  • Sir Brian Pippard

    Updated: 2024-04-22 05:30:21
    I am saddened to hear about the death of Brian Pippard. Pippard made pioneering studies into the field of superconductivity at the University of Cambridge, including foundations for the BCS theory, and the introduction of the coherence length and the non-local model. He demonstrated real insight in both experiment and theory. See here for an […]

  • A fridge is born

    Updated: 2024-04-22 05:30:19
    New arrival in the lab! Our new dilution refrigerator from ICEOxford. We’re currently installing extra thermometry to prepare for the first run. It should reach base of ~12mK. So I thought, as usual, artsey pictures were necessary.
