4 Apr 2004 | | Journal: | Phys.Rev.Lett. 92 (2004) 196806 | | Subject: | Mesoscopic Systems and Quantum Hall Effect | cond-mat.mes-hall | | Abstract: | Most of the fractions observed to date belong to the sequences $
u=n/(2pnpm 1)$ and $
u=1-n/(2pnpm 1)$, $n$ and $p$ integers, understood as the familiar {em integral} quantum Hall effect of composite fermions. These sequences fail to accommodate, however, many fractions such as $
u=4/11$ and 5/13, discovered recently in ultra-high mobility samples at very low temperatures. We show that these "next generation" fractional quantum Hall states are accurately described as the {em fractional} quantum Hall effect of composite fermions. | | Source: | arXiv, cond-mat/0404079 | | Services: | Forum | Review | PDF | Favorites | |
