David tong quantum hall effect.
The quantum Hall effect. Modern electronics is being transformed as device size decreases to a size where the dimensions are significantly smaller than the constituent electron's mean free path. In such systems the electron motion is strongly confined resulting in dramatic changes of behaviour compared to the bulk.

An Introduction to the Quantum Hall Effect. The Quantum Hall Effect is a fascinating phenomenon that occurs in two-dimensional electron systems subjected to low temperatures and strong magnetic fields. It was first discovered by German physicist Klaus von Klitzing in 1980, for which he was awarded the Nobel Prize in Physics in 1985.

qhe. 5. Chern-Simons Theories. So far we’ve approached the quantum Hall states from a microscopic perspective, look-ing at the wavefunctions which describe individual electrons. In this section, we take a step back and describe the quantum Hall e↵ect on a more coarse-grained level. Our goal is to construct e↵ective field theories which ...Fractional Quantum Hall Effect (FQHE) is a typical strong-correlated system. Jain proposed his composite fermion (CF) theory in 1989 in which CF is introduced as a weakly coupled degree of freedom. For a pedagogical review of the CF theory, see David Tong's lecture [2]. We use Density Functional Theory (DFT) to compute FQHE in CF theory in …1.3 Quantum Hall E↵ects Now we understand the classical expectation.

The quantum Hall effect is a typical realization of topological effects in condensed matter physics. In this article, some of the topological aspects of the quantum Hall effect are reviewed.Yang-Mills instantons are solitonic particles in d = 4 + 1 dimensional gauge theories. We construct and analyse the quantum Hall states that arise when these particles are restricted to the lowest Landau level.

ADHM and the 4d Quantum Hall Effect. Alec Barns-Graham, Nick Dorey, Nakarin Lohitsiri, David Tong, Carl Turner. Yang-Mills instantons are solitonic particles in d=4+1 dimensional gauge theories. We construct and analyse the quantum Hall states that arise when these particles are restricted to the lowest Landau level.From the simple picture that extended states form only at the center of each Landau level and all the other states are localized, we can explain the origin of the Quantum hall plateaux. Because the current is carried only by the states at the center of each Landau level, the current should jump discontinuously as the Fermi level is tuned ...
