Indices Commodities Currencies StocksThis non-linear Hall effect has a quantum origin: it is related to the geometric properties of the electronic wavefunctions and encoded in the dipole moment of the Berry curvature. Here, the general theory underpinning this effect is reviewed and various material platforms where non-linear Hall transverse responses have been found are discussed.David Tong: Lectures on Vector Calculus.

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.Abstract. We discuss anomalous fractional quantum Hall effect that exists without external magnetic field. We propose that excitations in such systems may be described effectively by non-interacting particles with the Hamiltonians defined on the Brillouin zone with a branch cut. Hall conductivity of such a system is expressed through …About Press Copyright Contact us Creators Advertise Developers Terms Privacy Policy & Safety How YouTube works Test new features NFL Sunday Ticket Press Copyright ...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.

The second technique is Chern–Simons field theory. Originally a product of the imaginations of the mathematicians S. S. Chern and J. Simons, it first entered particle physics in the work of Deser, Jackiw, and Templeton [10], and then condensed matter [11–14]. I will describe its role in the FQHE after introducing the problem to you.

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 ...

Magnetic fields give rise to new fundamental behaviors not observed in bulk‐like systems, such as the quantum Hall effect. In mesoscopic systems, a static magnetic field may have a profound effect on the electronic and transport properties. The application of high magnetic fields to these mesoscopic devices is an invaluable degree of freedom ...

Lecture notes will become available as the lectures progress. Content . 1. From Spins to Fields: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.INTRODUCTION.
