The Fractional Quantum Hall E↵ect We’ve come to a pretty good understanding of the integer quantum Hall e↵ect and the reasons behind it’s robustness. Indeed, some of the topological arguments in the previous chapter are so compelling that you might think the Hall resistivity of an insulator has to be an integer.The first experiments exploring the quantum regime of the Hall effect were performed in 1980 by von Klitzing, using samples prepared by Dorda and Pepper 1 1 1 K. v Klitzing, G. Dorda, M. Pepper, “ New Method for High-Accuracy Determination of the Fine-Structure Constant Based on Quantized Hall Resistance ”, Phys. Rev. Lett. 45 494.. The ... This doubling indeed happens in the "quantum spin Hall effect", but those systems are at zero magnetic field (and moreover enjoy time reversal symmetry, which is key). However, in the usual quantum Hall effect, there is a huge static magnetic field, which polarizes all the low energy electrons (the Zeeman splitting is large because it goes like ...

1. In David Tong's notes on the quantum hall effect, when calculating the current due to edge modes, he writes it's expression as. Iy = −e ∫ dk 2πvy(k) I y = − e ∫ d k 2 π v y ( k) where vy v y is the drift velocity of the state with momentum ℏk ℏ k. But I fail to understand how that gives the current.The quantum Hall effect (or integer quantum Hall effect) is a quantized version of the Hall effect which is observed in two-dimensional electron systems subjected to low temperatures and strong magnetic fields, in which the Hall resistance Rxy exhibits steps that take on the quantized values. where VHall is the Hall voltage, Ichannel is the ...analyze the Hall effect in the plateau region relative to the fundamental value 2 h/e i expected in the simple one-electron picture for integer filling factors of Landau levels.
