1.3 The Classical Hall E ect Let us rst look at the classical Hall e ect and then see how it di ers from the quantum Hall e ect. The integer quantum Hall effect is peculiar due to the zero energy Landau level. Theory for the Charge-Density-Wave Mechanism of 3D Quantum Hall Effect Fang Qin (覃昉) ,1,2,3 Shuai Li,1 Z.Z. The basic results are ˙ xx= 0 and ˙ xy= e2=h, in which is the integer quantum num-ber. El efecto Hall cuántico y sus contextos scientiæ zudia, São Paulo, v. 11, n. 1, p. 141-58, 2013 Hall reconoce que su motivación para intentar realizar el experimento, con lo cual explora la eventual validez de la observación de Maxwell, estuvo también influen- Introduction: materials, transport, Hall effects ?integer quantum Hall effect: resolved Landau levels with localization between centers of Landau levels?low disorder 2D electron systems show fractional quantum Hall effect – correlations of electrons as described by the Laughlin wave function?what about many fractional quantum Hall states? Anyons, Fractional Charge and Fractional Statistics. The discovery of the quantum Hall effect (QHE) marked a turning point in condensed-matter physics. Observation of Quantum Hall effect in an ultra-thin (Bi 0.53Sb 0.47) 2Te 3 film Wenqin Zou,1,a) Wei Wang,2,a) Xufeng Kou,3 Murong Lang,3 Yabin Fan,3 Eun Sang Choi,4 Alexei V. Fedorov,5 Kejie Wang,2 Liang He,2,3,b) Yongbing Xu,2,b) and Kang. Band, Yshai Avishai, in Quantum Mechanics with Applications to Nanotechnology and Information Science, 2013. To date however, rare clear-cut examples concern-ing topologically ordered phases of Bose-Fermi mixtures which possess diverse quantum particle statistics, have been conclusively sought for. Integer Quantum Hall Effect in Graphene. The basic experimen- Non-Abelian Quantum Hall States: PDF Higher Landau Levels. I. Topological quantum numbers in the Hall eﬀect J. E. Avron1, D. Osadchy1 and R. Seiler2 1 Department of Physics, Technion, 32000 Haifa, Israel 2 Department of Mathematics, TU Berlin, Berlin, Germany February 6, 2008 Abstract Topological quantum numbers account for the precise quantization that occurs in the integer Hall eﬀect. tional quantum Hall eﬀects and of superconducting high Tc cuprates [9]. Quantum Hall Hierarchy and Composite Fermions. Two prominent ones are • Prange and Girvin, “The Quantum Hall Eﬀect” This is a collection • Quantum Hall effect 55 Skipping cyclotron orbits Four-terminal sample configuration to measure the Hall and longitudinal resistivities • Quantum Hall effect 56 •For a given plateau not a perfect conductor, ρ xx = 0, ρ xy!= 0 ⇒ electrons move with zero longitudinal resistance. 4 Orbifold Quantum Hall States Charles L. Kane Department of Physics and Astronomy, University of Pennsylvania, Philadelphia, PA 19104 Ady Stern Department of Condensed Matter Physics, The Weizmann Institute of Science, Rehovot 76100, Israel We introduce a coupled wire model for a sequence of non-Abelian quantum Hall states that generalize the Z The quantum Hall e ect (QHE) is one of the most remark-able condensed-matter phenomena discovered in the second half of the 20th century, and our talk is mainly about the integer quantum hall e ect. Pfeiffer and K.W. For all three quantum Hall effects, electrons flow through the lossless edge channels, with the rest of the system insulating. The classical Hall e ect was discovered by Edwin Hall in 1879. For a quantum Hall fluid on two dimensional tori this viscosity is computed.
