In the so-called integer quantum Hall e ect (IQHE) discovered by von Klitzing in 1980, the quantum number is a simple integer with a precision of about 10 10 and an absolute accuracy of about 10 8 (both being limited by our ability to do resistance metrology).

About Press Copyright Contact us Creators Advertise Developers Terms Privacy Policy & Safety How YouTube works Test new features Press Copyright Contact us Creators 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.

Because of this kind of striking behaviour, the quantum Hall e ect has been a con- stant source of new ideas, providing hints of where to look for interesting and novel phenomena, most of them related to the ways in which the mathematics of topology

The 1980 discovery of the quantum Hall effect kicked off the study of topological orders, electronic states with "protected" patterns of long-range quantum entanglement that are remarkably robust. 40 years of the quantum Hall effect Abstract. The discovery of the quantum Hall effect (QHE) marked a turning point in condensed-matter physics. The The contributors. Klaus von Klitzing received the Nobel Prize in Physics in 1985 for discovering the quantum Hall References. Klitzing, K. v., The quantum Hall effect is an example of a phenomenon having topological features that can be observed in certain materials under harsh and stringent laboratory conditions (large magnetic field, near absolute zero temperature).

On Aspects of Anyons and Quantum Graphs On one hand, topological phenomena have played a central role in the quantum Hall effect for many years. More recently, the non-Abelian quantum Hall states The Quantum Hall Effect (QHE) discovered by von Klitzing was the first known topological state of matter.

Quantum entanglement is a physical phenomenon that occurs when a group of particles is generated, interact, or share spatial proximity in a way such that the quantum state of each particle of the group cannot be described independently of the state of the others, including when the particles are separated by a large distance.

If certain conditions are met, We have considered the response at two energies corresponding to two plateaus in the quantum Hall effect. Since the thermoelectric power involves the Preprint.
