David tong quantum hall effect
I'm following David Tong's lectures on the Quantum Hall Effect, in which he rederives the TKNN formula using the Kubo formula. The notes are a understandably hand-wavy with notation, so let me provide some preliminaries.David Tong: Lectures on Classical Dynamics. This is a second course in classical mechanics, given to final year undergraduates. They were last updated in January 2015. Individual chapters and problem sheets are available below. The full set of lecture notes, weighing in at around 130 pages, can be downloaded here: PostScript PDF HTML.David Tong: Lectures on Vector Calculus. These lectures are aimed at first year undergraduates. They describe the basics of div, grad and curl and various integral theorems. The lecture notes are around 120 pages. Please do email me if you find any typos or mistakes.

The fractional quantum Hall effect is a very counter- intuitive physical phenomenon. It implies that many electrons, acting in concert, can create new particles having a chargesmallerthan the charge of any indi- vidual electron. This is not the way things are supposed to be.chakraborty, t, fractional quantum hall-effect at even-denominator filling fractions, physical review b 38: 10097 (1988). google scholar. chang, a.m., transmission and reflection probabilities between v=1 and v=2/3 quantum hall-effects and between v=2/3 and v=1/3 effects, solid state communications 72: 651 (1989).The original, classical Hall effect was discovered in 1879 by Edwin Hall. It is a simple consequence of the motion of charged particles in a magnetic field. The setup for the same is as follows, consider a rectangular bar with thickness, t, Length L, and width W, as shown in Fig 1. Now a constant current along the x axis is passed.David Tong - Quantum Hall Effect Lecture Series - 2016.

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. We describe the ground state wavefunctions for both Abelian and non-Abelian quantum Hall states. Although our model is purely …David Tong: Lectures on Statistical Field Theory. These lecture notes provide a detailed introduction to phase transitions and the renormalisation group, aimed at "Part III" (i.e. masters level) students.

PDF HTML.Over the past 40 years, the quantum Hall effect (QHE) has inspired new theories and led to experimental discoveries in a range of fields going beyond solid-state electronics to photonics and ...But the world is governed by quantum mechanics. This becomes important at low temperatures and strong magnetic fields where more interesting things can happen. It’s useful to distinguish between two di↵erent quantum Hall e↵ects which are asso-ciated to two related phenomena. These are called the integer and fractional quantum Hall e↵ects.Unless you're a pro basketball player, we all have one or two shelves in our kitchen that are just too darn tall to reach.

Dec 15, 2015 · Abstract. We introduce a supersymmetric Chern-Simons theory whose low energy physics is that of the fractional quantum Hall effect. The supersymmetry allows us to solve the theory analytically. We quantize the vortices and, by relating their dynamics to a matrix model, show that their ground state wave function is in the same universality class ...
