The AMO optical lattice systems have two main virtues: they are very clean (meaning that they can be described by a small number of parameters) and very tunable. DNA structures, on the other hand, are quite complicated. The molecules are surrounded by water and dissolved ions, and they're also floppy. Moreover, the way electrons and ions move around in DNA structures tends to be complicated and incoherent, in the sense that quantum coherent effects are not important while thermally driven processes are. Both AMO lattices and DNA structures are cool, but they're really different.Douglas Natelsonhttps://www.blogger.com/profile/13340091255404229559noreply@blogger.comtag:blogger.com,1999:blog-13869903.post-32914115597558273722010-06-18T15:24:17.290-05:002010-06-18T15:24:17.290-05:00Professor Natelson,

I know from reading the Wikipedia article that people have tried and had various degrees of success in creating DNA nanotubes, 2D lattices, discrete 3D objects, and extended 3D lattices, among other artificial structures. <br /><br />I know that the AMO community has for quite some time now been using cold atom systems to experimentally "simulate" condensed matter and statistical mechanics models (such as the Hubbard model, Anderson model, etc...) to a near unprecedented degree of control and precision. What are the possibilities, if any, of using such DNA construction to add similar types of insight to condensed matter physics? Have people thought about it?Pizza Perusing Physicisthttps://www.blogger.com/profile/02213655278674258393noreply@blogger.comtag:blogger.com,1999:blog-13869903.post-68779176684719907322010-06-16T13:30:30.217-05:002010-06-16T13:30:30.217-05:00Bear in mind that the Kavli Foundation just starte...Bear in mind that the Kavli Foundation just started awarding these in 2008, and this is only the second set.Douglas Natelsonhttps://www.blogger.com/profile/13340091255404229559noreply@blogger.comtag:blogger.com,1999:blog-13869903.post-16602692703370727712010-06-16T10:47:06.520-05:002010-06-16T10:47:06.520-05:00Thanks for this post.
