Apr 9, 2018 · 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 bosonic, we show that the excitations of this 4d quantum ...

The Integer Quantum Hall (IQH) Effect shows that this resistivity is quantized to extraordinary precision in inte-ger multiples of fundamental flux when the conductor is brought to very low temperatures. A satisfactory model of IQH states emerges from a non-interacting model of the electrons in the conductor and a band structure of these states ...

The Quantum Hall Effect TIFR Infosys Lectures David Tong Department of Applied Mathematics and Theoretical Physics, Centre for Mathematical Sciences, Wilberforce …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 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: Lectures on Dynamics and Relativity.
