In two dimensions, when classical electrons are subjected to a magnetic field they follow circular Density of states. Commonly it is assumed that the precise shape of Landau levels is a Gaussian or Lorentzian profile. Longitudinal resistivity. It is The quantum anomalous Hall effect is defined as a quantized Hall effect realized in a system without an external magnetic field. The quantum anomalous Hall effect is a novel manifestation of topological structure in many-electron systems and may have 2020-07-23 · The discovery of the quantum Hall effect (QHE) marked a turning point in condensed-matter physics. The measurement of the Hall resistance showed that electronic resistance could be defined A relativistic version of the quantum spin Hall effect was introduced in the 1990s for the numerical simulation of chiral gauge theories; the simplest example consisting of a parity and time reversal symmetric U(1) gauge theory with bulk fermions of opposite sign mass, a massless Dirac surface mode, and bulk currents that carry chirality but not charge (the spin Hall current analogue). 2021-01-30 · The quantum Hall effect is a well-accepted theory in physics describing the behavior of electrons within a magnetic field at extremely low temperatures.
In recent years, the quantum anomalous Hall effect was proposed theoretically and realized The quantum Hall effect (QHE) with quantized Hall resistance plateaus of height h/νe 2 was first observed in two-dimensional (2D) electron systems in 1980 . Here, h is Planck's constant, ν is Landau filling factor and e is electron charge.

The integer quantum Hall effect is c haracterized by plateaus at quantized integer values in the Hall resistance vs magnetic field plot. The Hall conductance σ xy = Our work on the quantum spin Hall (QSH) effect is motivated both by the quest for spin based electronic devices and by the search for topologically non-trivial states of matter. Unlike logic devices based purely on charge current, quantum spintronic devices integrate information processing and storage units, The quantized Hall effect (QHE) was discovered early in February 1980, when Klaus von Klitzing performed a series of experiments at the high-field magnetlaboratories in Grenoble, France, in order to Quantum Hall Effect is a quantum-mechanical version of the Hall Effect, observed in two-dimensional electron systems subjected to low temperatures and strong magnetic fields, in which the Hall conductance σ undergoes quantum Hall transitions to take on the quantized values.

In the year 1980, the Quantum Hall Effect (QHE) was discovered by Klaus von Klitzing, who was awarded the Nobel Prize for this work just five years later. He investigated the Hall-voltage of a 2DEG of a Silicon-MOSFET as a function of the charge carrier density at low temperatures and with large magnetic fields applied. More recently, the quantum anomalous Hall effect was observed for the surface Dirac state in magnetic topological insulator thin films (5, 6). To expand potential application of such a distinct quantum transport enriched by magnetic order, it is highly desirable to explore bulk systems that host various magnetism and dimensionality.
