Itâ€™s not valid at energies larger than or comparable to the splitting between z sub bands. I do find it interesting that you can have this rather exotic description of the low energy excitations of the interacting electronic system, and as the energy scales crank up it has to fail, leaving you with much more boring many electron states.

All physical systems are at best quasi-2D. There is an experimental way to think about a quasi-2D system, just turn off out-of-plane couplings until they are irrelevant. This "turning off" is generally a continuous process, there are well-defined experimental ways to do it. <br /><br />On the other hand, quantum statistics are not continuously adjustable things. You have one type of statistic, or you have another. Mathematically, there isn't a method for turning 2D space where anyon statistics holds into 3D space where they don't. It has always been unsatisfying to me that the topic of anyon statistics being destroyed by gradually turning the quasi-2d system into a 3d one is ignored most of the time.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-13869903.post-80743697303877379872020-04-12T14:58:59.143-05:002020-04-12T14:58:59.143-05:00It beggars the imagination that physicists worry s...It beggars the imagination that physicists worry so much about particle indistinguishability. We can take QFT to be about the expected statistics of measurement results associated with a field of possible measurements, which leads to zero such concerns. Physicists seem almost to enjoy all the pretzeled explanations required as soon as we insist that at root quantum FIELD theory is about particles. No, better to think of it as about fields (specifically, about fields of measurements and their expected statistics, so it's very much more like a <i>random</i> field.)Peterhttps://www.blogger.com/profile/08654675777726560464noreply@blogger.com
