Classic Edition: Subatomic Botany

Since I found myself talking about particle physics yesterday, and since I find myself in the middle of a seasonal allergy flare-up that’s sapping my bloggy motivation, I thought I would dust off and re-post some old articles about particle physics. These date back to 2003, but I think they still stand up reasonably well. […]

Amazing Laser Party!

While checking out the official Nobel Prize web site to see when the prizes will be announced, I was surprised to discover that the Nobel Foundation offers little Flash games on their web site. In particular, I had to check out the Laser Challenge site. Oh. My. God. Maybe it’s just the cold talking, but […]

Paranoia, the Destroyer

I’m in the middle of what is either a fall cold or a seasonal allergy flare-up– I lean toward the latter, for various reasons that don’t really matter. The important thing is, my head feels like it’s stuffed with cotton balls and vacuum pump oil. This isn’t the real gripe of the moment, though. The […]

Counting Leptons

Quantum Diaries survivor Tommaso Dorigo offers an inside look at experimental particle physics, describing new results from combing through CDF data to look for rare events producing two leptons with the same charge: Indeed, 44 events were found when 33.7 were expected, plus or minus 3.5. That corresponds to a roughly 2-sigma fluctuation of expected […]

It’s a Technical Term

Dave Bacon explains heating-induced decoherence: One problem with ion traps qubits has been the heating of the motional degrees of the trapped ions, due mostly to fluctuating potentials on the trap electrodes. The electrode potential goes yee-yaw and the ion goes wee-wah, heating up and thus ruining the motional degree of freedom of the ion. […]
