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.
Fishnet structure gives negative permeability
Single photon observed hundreds of times without being destroyed
APS memorabilia: these will be worth a fortune on eBay someday. I actually didn’t buy an APS t-shirt — or a bumper sticker, slinky or travel mug — but I’m still glad I came to Denver. Here’s some miscellany I learned today. • There are no guns allowed in the Colorado Convention Center — but […]
What’s the best way to determine the structure of a molecule that cannot be integrated within a periodic lattice? Blow the heck out of it using x-ray pulses from the Linac Coherent Light Source (LCLS) — at least according to SLACs Philip Bucksbaum. The LCLS will open next year at SLAC in California and will […]
IOP Publishing’s reception was a big hit last night, judging by the fact that the buffet had to be replenished several times — you can work up a huge appetite running back and forth between sessions for nearly 10 hours a day. I spent most of my time talking to IOP referees and journal board […]
Some of the most interesting condensed matter physics occurs at very low temperatures and physicists need accurate ways of knowing just how cold their samples are. Traditionally, this has meant spending hours building, calibrating and troubleshooting temperature measurement and control systems — instead of actually doing the experiments. Those days are over in many labs […]
I was having so much fun with the physicists that I nearly forgot to check out the exhibition before it closed for good this afternoon. First stop was the IOP Publishing stand where I had a chat with Sharice Collins, who is our senior marketing manager for the Americas. Sharice is based in our Philly […]
Here’s a new recipe from Jeffrey Brinker of the University of New Mexico (P42 1) Mix together water, alcohol, detergent, silica and a good dollop of single-cell organisms. Dip in a substrate of your choice. Remove and let dry. While you do the washing up, the silica, detergent and cells will be busy organizing themselves […]
What? Not Mott? Pots not dots, lots per pot …and hot! You can only get away with describing your experiment with a poem if you have a Nobel Prize — and JILA’s Eric Cornell has one of them. The pots are the wells within a two-dimensional optical lattice and they were filled with lots of […]
