QM Oxford
Добавлен 1 ноя 2017
Welcome to the channel of the Quantum Materials group in the Department of Physics at the University of Oxford!
Many of today's most interesting materials are 'quantum materials', with properties that can only be described using the theory of quantum mechanics. The Quantum Materials group in Oxford Physics investigates the exciting and often spectacular phenomena displayed by these materials, in order to understand the materials and put them to good use.
On this channel, we hope to provide an insight into what quantum materials are and why they are worth studying, as well as introducing some of the physics involved. There will be short introductory videos as well as longer lectures on different topics related to quantum materials.

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.

Monopole Hunters - QM Winter Workshops
Просмотров 2523 года назад
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/...

Frontiers in Computing - Matthew Steggles - QM Seminars
Просмотров 4854 года назад
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...
Neutron Scattering in Quantum Magnetism - Miska Elliot - QM Seminars
Просмотров 2,3 тыс.4 года назад
How can we probe the inner workings of quantum materials? And how can neutrons help us? In this short talk, Miska Elliot introduces the ideas behind a technique called neutron scattering, a useful tool used in Condensed Matter Physics to measure physical properties of both solids and liquids. Miska explains why this is a useful technique, where and how contemporary neutron scattering experiment...
Magnificent Muons - Johnny Wilkinson - QM Seminars
Просмотров 5124 года назад
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,...
Making Waves in Magnetism - Dr Alexy Karenowska - QM Seminars
Просмотров 1 тыс.4 года назад
What connects the Trojan War, the Severn Bore, and electronic devices so new they haven't even been invented yet? In this seminar, Dr Alexy Karenowska lifts the lid on the familiar - yet mysterious - phenomenon of magnetism and explores some of the less well-known aspects of its fascinating physics. In particular, Dr Karenowska introduces the spin wave, an interesting variety of magnetic wave w...
The Many Universes of Quantum Materials - 2019 Quantum Materials Public Lecture
Просмотров 2,8 тыс.5 лет назад
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 is EMT magnetic oil
We take Simple everyday reality for granted. But take the time to scratch the surface very fascinating lecture.
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.
Why are magnets called marvellous
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?
This presentation was awesome fantastic.

Nice video
Nice video
Great video, I always struggle to explain this concept to my chemistry students. Thank you!!!
This helped me thank you ☺️
amazing lecture
Interesting to know how diamagnetism work
Thank you for explaining this and bringing it down to a level I can understand. Nicely done.
Such a splendid display,, howw did u make it ??? ^3^
Wow... Thank you for uploading!
Wow, nice explanation!
So glad to find this on you tube. I have to teach online from time to time, and I didn't think I could find this experiment online. Thank you
Nice explanation
Thank you.
So it is impossible to separate North and South poles Wow this is amazing!
amazing explanation
Thanks David!
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?
Thank you
That beeping is irritating.
It's the oxygen monitor - we have to have it if we're using liquid nitrogen.
@@qmoxford3355 Thanks for the reply, It seems like the red tape department has turned feral, and about to asphixiate Oxford.
Great video. Thank you!
I didn't expect the results of this experiment. Thanks for the video.
Very nice lecture!
👍♥️
Great lecture but the video should focus more on the screen than the speaker
Thanks for the feedback! We'll bear it in mind when we do the next lecture.
We look forward to the series. Even though we specialise in magnetic test equipment such as Teslameters and VSMs etc, we are always intrigued by magnets and magnetism.
I'm sorry Dr Stephen Blundell. Despite my respect I have for you from what I have learned at the moment, your presence were clearly inferior to that of Trump's symmetrical face that 'trumps' over all possible beauties of this world.🤣🤣🤣
