I am an online editor of Physics World. I did a PhD in condensed-matter physics at McMaster University in Canada. I am still fascinated by what is an extremely rich and varied subject that I believe is ignored by the media (Physics World excepted, of course). As a result, I’m happiest when I’m blogging about topological insulators, the latest quasiparticle or some other quirk of condensed matter. So, if you spot something weird and wonderful in solid-state physics, please get in touch. In my spare time I am a Scout leader.

Weathering the storm

Weathering the storm

"You can flood a city, but you can't drown a university", says Greg Seab, a physicist at the University of New Orleans who was speaking at a press conference on the impact of Katrina on local physics departments.

Happy Birthday, PRL

Happy Birthday, PRL

That’s some cake! Yesterday evening my IOP Publishing colleagues and I managed to blag our way into a posh reception celebrating 50 years of the journal Physical Review Letters. I forgot to take my camera, so the photo is courtesy of James Riordon at the APS. And yes, we did sing: Happy birthday Physical Review […]

A new spin on silicon and graphene

A new spin on silicon and graphene

At last year’s March Meeting in Denver, Ian Appelbaum gave a ten-minute talk about how he had injected spin-polarized electrons into a piece of silicon, transported them micrometres and then detected a spin-polarized current at the other end. It was just one of thousands of talks given that year. But then Appelbaum published his results […]

Black holes as quantum-information mirrors

Black holes as quantum-information mirrors

This is the tale of Alice, Bob and a black hole. Alice and Bob are a couple with a big communication problem — they only talk using quantum information systems. Usually this involves sending encrypted messages via quantum dots or entangled photons, which are unreliable at the best of times. But now Caltech’s John Preskill […]
