From Rust to Riches - Prof Paolo Radaelli - QM Public Lecture 2021
Could rust be the secret to next-gen computing technology?
Current silicon-based computing technology is incredibly energy-inefficient and with climate change still a major challenge for humanity, finding ways to decarbonise tech is an obvious target for energy savings. Could rust provide the answer?
In this talk, explore how the magnetic properties of oxides of common metals like iron (aka rust) might offer a solution, and learn how inspiration for this exciting research came from the most unlikely of sources: cosmic strings.
Professor Paolo G. Radaelli is Dr Lee’s Professor of Experimental Philosophy at the Clarendon Laboratory, University of Oxford, and Associate Chairman of Physics. His main interest is the study of transition metal oxides displaying novel physical phenomena, such as high-temperature superconductivity, “colossal” magneto-resistance or multiferroics behaviour, with the potential of device applications.
This lecture was given as the 2021 Quantum Materials Public Lecture in February 2021.

Monopole Hunters - QM Winter Workshops
Переглядів 2273 роки тому
Join us on the hunt for the elusive magnetic monopole! You will probably know that magnets have two poles: a North and a South. Could we ever find a magnet with just one of these poles - a 'magnetic monopole'? See how we might detect these monopoles and what one might look like, or even sound like. Hunt for monopoles in our free downloadable activity booklet - link below: www2.physics.ox.ac.uk/...

How can we use molecules in computing? And what do knots have to do with quantum computers? Computers in the regular sense are used by all of us every single day. Furthermore, the past 5 years has seen a huge growth in quantum computing, which is bursting out of research and on the verge of becoming a full on industry. A natural question to ask is: how do we make computers, both classical and q...

What does Particle Physics have to do with Quantum Materials? And what even is a muon? Often, Quantum Materials and Particle Physics are seen as two completely separate branches of Physics. But it turns out that there is one particle, the muon, which despite only surviving for 2 millionths of a second, has properties that make it really useful for studying quantum materials. In this short talk,...

Professor Stephen Blundell explores the many universes of quantum materials for the 2019 Quantum Materials Public Lecture. Physicists try to find the laws that govern the Universe, discover new particles and explain phenomena. But what if the rules that govern the Universe were different? What would happen then? This question is not just an academic one. Every new material discovered is behaves...

    What if particles are made of classical information? Would the scattering events represent classical computation? It appears, as if there is a parallel between qft and classical computing - quantum field and its effective field can be likened to the host(the emulator) and the guest. Fractal fields and emulators also seem to be possible.

    Hey, nice ties and knots, sun glasses and cheap school boys calculators - to explain how billion pounds beamlines work to "see magnetic-cosmic string related concepts" within RUST with potential immediate (???) application that makes data storage potentially RICH because RUST is CHEAP : is it SERIOUS? Compared to... what I could see you present in a Neutron Conference in Budapest around 1999, what I consider as far more interesting fundamental Colossal magnetic oxides/Superconductors work, showing the importance of phase separation in PrCaMnO3 manganites, proper (ie modest) and inspirational Science advances you were making using HRPD in ISIS on materials very hard to understand. Have you followed the development of that Field of research for the past 20 years? In particular there had been a long term debate since 2002 whether the symmetry of R0.5Ca0.5MnO3 (R : La, Pr) manganites is P 21/m or P 21 n m? God knows, you're a CRYSTALLOGRAPHER highly cited in this Field, and it's the KEY CRYSTAL that has "Stripe order" intimately related to the Secrets of High temperature Superconductivity! So, where are we now? Is it still EVIL ALCHEMY, who decide what's the SCIENTIFIC answer?

    I always wanted to know this. Question is, WHY? What makes magnets behave that way? Why does have to be north or south, positive or negative. What determines that? There seems to be no end. Not even till you get to even the smallest of particles. Even smaller than Atoms, I imagine. A mystery to me. Thanks for sharing this. As I said, I always wanted to know what would have "if". But I also want to know why?
