8 Aug 2000 | | Subject: | Mesoscopic Systems and Quantum Hall Effect; Strongly Correlated Electrons | cond-mat.mes-hall cond-mat.str-el | | Abstract: | We consider a fully spin-polarized quantum Hall system with no interlayer tunneling at total filling factor $
u=1/k$ (where $k$ is an odd integer) using the Chern-Simons-Ginzburg-Landau theory. Exploiting particle-vortex duality and the concept of quantum disordering, we find a large number of possible compressible and incompressible ground states, some of which may have relevance to recent experiments of Spielman {it et.al.}. We find interlayer coherent compressible states without Hall quantization and interlayer-incoherent incompressible with Hall quantization in addition to the usual $(k,k,k)$ Halperin states, which are both interlayer-coherent and incompressible. | | Source: | arXiv, cond-mat/0008137 | | Other source: | [GID 1140903] pmid11290265 | | Services: | Forum | Review | PDF | Favorites | |
