Temperature dependence of spin polarizations at higher Landau Levels | | Tapash Chakraborty

3 Oct 1999 | | Subject: | Mesoscopic Systems and Quantum Hall Effect | cond-mat.mes-hall | | Affiliation: | Max Planck Institute for Physics of Complex Systems, Dresden, Germany) and Pekka Pietiläinen (Theoretical Physics, University of Oulu, Oulu, Finland | | Abstract: | We report our results on temperature dependence of spin polarizations at $
u=1$ in the lowest as well as in the next higher Landau level that compare well with recent experimental results. At $
u=3$, except having a much smaller magnitude the behavior of spin polarization is not much influenced by higher Landau levels. In sharp contrast, for filling factor $
u=frac83$ we predict that unlike the case of $
u=frac23$ the system remains fully spin polarized even at vanishingly small Zeeman energies. | | Source: | arXiv, cond-mat/9910019 | | Services: | Forum | Review | PDF | Favorites | |
