Cameron and Avatar

Somehow I forgot to point this out last Fall. There was an interesting article by Dana Goodyear in the New Yorker on James Cameron, creator of so many giant films you may know of, and of course, of the recent juggernaut Avatar. It is definitely worth a read, as is Goodyear’s related chat online with readers here.

I went to see Avatar in its proper setting (late night showing in the Dome at the Arclight of course) a fortnight ago and can report a few things of interest:

* The cheeky alternate name Smurfohantas (I heard this name on Kermode and Mayo’s BBC Radio 5 show) is not far off the mark if you are in a cynical mood. It’s a very standard story, rather straightforwardly told, but using striking tall blue people. (There is nothing wrong with re-telling stories, by the way, so don’t get me wrong. Arguably, most stories are in large part old stories). I just don’t see this version as particularly well told, just merely functional. There’s a slightly more interesting angle buried under there somewhere about the whole idea of avatars, and maybe even something about disability, and so forth, but only if you really really dig for it.

* It is not a great film, but it is an interesting and entertaining film to watch. I have a soft spot for Cameron’s work since I do like his use of strong female characters in the genre as well as his anti-war, suspicion-of-corporation, and environmental […] Click to continue reading this post →

News From The Front, VIII: One Down…

work_snap…more to go. I’ve finished one of the papers I’ve been writing (this one co-authored with my student, Tameem) after delaying on it for months. I’m not sure how things got quite this backed up in terms of things I have to do, but they have. I meant to start on a new, long project last week, and all my efforts these days have been toward clearing away all those things I want to get done and dusted before focusing on that. It is taking time, but gradually the clearing is happening. Two more manuscripts to complete.

This paper reports on the continuation of the work we’ve been doing over the years in understanding the physics of various model systems in an applied magnetic field. This is in the context of holographic models of important strongly coupled phenomena that are of considerable interest in lots of fields of physics (particle physics, nuclear physics, condensed matter physics, atomic physics). (Since I don’t want to explain holography and so forth every time I talk about it, see a post I did about some of that here, and related posts in the list at the bottom of this one, if not sure what I’m talking about.) (Hmmmm, I see from my SPIRES listing that I’ve got seven papers mentioning magnetic field explicitly in the title in the last three years, and three or four more of the rest are occupied in large part with the issue too. No, really, I’m not obsessed.)

The issue here is the study of structures that suggest themselves as earmarks of Fermi surfaces in strongly coupled systems. It has been a goal for a long time in the context of gauge/gravity duals to understand what the signals of a Fermi surface would be. Would it be some geometrical object in the dual gravity theory, perhaps? Access to a computationally tractable description of such an object would be rather […] Click to continue reading this post →
