Quantum transport in $
u=2/3$ spin-singlet quantum Hall edges | | Ken-ichiro Imura

31 Oct 1997 | | Journal: | Phys. Rev. B57, R6826 (1998). | | Subject: | cond-mat | | Abstract: | Tunneling conductance $G(T)$ through a constricted point contact is studied for the $
u=2/3$ spin-singlet edges. Including spin-flip tunneling, Zeeman splitting and random magnetic impurities, we discuss the various crossovers of $G(T)$ as a function of the temperature $T$. The behavior of $G(T)$ is found to be quite different for spin-singlet and spin-polarized cases, and hence $G(T)$ is expected to serve as an experimental probe for the polarized-unpolarized transition at $
u=2/3$. | | Source: | arXiv, cond-mat/9710342 | | Services: | Forum | Review | PDF | Favorites | |
