Note:These pages make extensive use of the latest XHTML and CSS Standards. They ought to look great in any standards-compliant modern browser. Unfortunately, they will probably look horrible in older browsers, like Netscape 4.x and IE 4.x. Moreover, many posts use MathML, which is, currently only supported in Mozilla. My best suggestion (and you will thank me when surfing an ever-increasing number of sites on the web which have been crafted to use the new standards) is to upgrade to the latest version of your browser. If that's not possible, consider moving to the Standards-compliant and open-source Mozilla browser.

New Fractional Branes

Very interesting paper today by Ashok, Dell’Aquila and Diaconescu. They construct a new class of boundary states (D-branes) on Landau-Ginzburg Orbifolds. Previous constructions clearly missed a large class of D-branes. In particular, there was no candidate for (what, at large radius corresponds to) the D0-brane on the Quintic. This led to a certain amount of speculation by Douglas and collaborators on the “fate” of the D0-brane.

Among the new class of boundary states found by these folks, is one that they say corresponds to the D0-brane.

I’m afraid I can’t say much about the technical details yet. Maybe in a few day, when I’ve gotten further into it.
