You may or may not have noticed that I’ve been making a concerted effort to do more ResearchBlogging posts explaining notable recent results. I’ve been trying to get at least one per week posted, and coming fairly close to that. I’ve been pretty happy with the fake Q&A format that I’ve settled into, and while… Continue reading ResearchBlogging by Proxy: Physics on “Coherent Light Scattering from a Two-Dimensional Mott Insulator”

Undergraduate Institutions at DAMOP Reception
One of the many things I’ve been occupied with the last few weeks has been arranging a reception at next week’s Division of Atomic, Molecular, and Optical Physics (DAMOP) meeting. I was late in asking about the possibilities for this, so it won’t make it to the printed program, which means I need to advertise… Continue reading Undergraduate Institutions at DAMOP Reception
Commanding the Power of Thor…ium: “Wigner Crystals of 229Th for Optical Excitation of the Nuclear Isomer”
I have to admit, I’m writing this one up partly because it lets me use the title reference. It’s a cool little paper, though, demonstrating the lengths that physicists will go to in pursuit of precision measurements. I’m just going to pretend I didn’t see that dorky post title, and ask what this is about.… Continue reading Commanding the Power of Thor…ium: “Wigner Crystals of 229Th for Optical Excitation of the Nuclear Isomer”
Watching Photons Interfere: “Observing the Average Trajectories of Single Photons in a Two-Slit Interferometer”
It’s been a long and brutally busy week here, so I really ought to just take a day off from blogging. But there’s a new paper in Science on quantum physics that’s just too good to pass up, so here’s a ReasearchBlogging post to close out the week. Aw, c’mon, dude, I’m tired. What’s so… Continue reading Watching Photons Interfere: “Observing the Average Trajectories of Single Photons in a Two-Slit Interferometer”
The Evil Professor Magic Trick
Back when I was an undergrad, we did a lab in the junior-level quantum class that involved making a dye laser. We had a small pulsed nitrogen laser in the lab, and were given a glass cell of dye and some optics and asked to make it lase in the visible range of the spectrum.… Continue reading The Evil Professor Magic Trick
Science Marches On
It’s been a hectic day here, so I haven’t had time to do any substantive blogging. I did want to quickly note a couple of stories presenting marked improvements in experiments I’ve written up here in the past: 1) In the “self-evident title” category, there’s Confinement of antihydrogen for 1000 seconds, which extends last year’s… Continue reading Science Marches On
Proving Einstein Wrong…ish: Measurement of the Instantaneous Velocity of a Brownian Particle
Last summer, there was a fair bit of hype about a paper from Mark Raizen’s group at Texas which was mostly reported with an “Einstein proven wrong” slant, probably due to this press release. While it is technically true that they measured something Einstein said would be impossible to measure, that framing is a little… Continue reading Proving Einstein Wrong…ish: Measurement of the Instantaneous Velocity of a Brownian Particle
Treating Photons Like Atoms: “Bose-Einstein condensation of photons in an optical microcavity”
This paper made a big splash back in November, with lots of news stories talking about it; it even made the #6 spot on Physics World‘s list of breakthroughs of the year. I didn’t write it up then because I was hellishly busy, and couldn’t take time away from working on the book-in-progress to figure… Continue reading Treating Photons Like Atoms: “Bose-Einstein condensation of photons in an optical microcavity”
Wave Nature Gets Bigger: “Quantum interference of large organic molecules”
It’s been a while since I wrote up a ResearchBlogging post, but since a recent paper forced me to update my “What Every Dog Should Know About Quantum Physics” slides with new pictures, I thought I should highlight the work on the blog as well. Not that you could’ve missed it, if you follow physics-y… Continue reading Wave Nature Gets Bigger: “Quantum interference of large organic molecules”
What’s So Interesting About AMO Physics?
I’ve got three months to decide. I’ll be giving an invited talk at the Division of Atomic, Molecular, and Optical Physics (DAMOP) with this title, with a goal of introducing the field to students and physicists from other fields: In recent years, DAMOP has expanded to the point where the meeting can be quite daunting… Continue reading What’s So Interesting About AMO Physics?
