The quantum Hall effect is a macroscopic quantum phenomenon in a two-dimensional electron system. The two-dimensional electron system in SrTiO3 has sparked a great deal of interest, mainly because

Current advances: The fine-structure constant and quantum Hall effect The fine-structure constant α is of dimension 1 (i.e., it is simply a number) and very nearly equal to 1/137. It is the "coupling constant" or measure of the strength of the electromagnetic force that governs how electrically charged elementary particles (e.g., electron, muon) and light (photons) interact.

Creating seamless heterostructures that exhibit the quantum Hall effect and superconductivity is highly desirable for future electronics based on topological quantum computing. However, the two topologically robust electronic phases are typically incompatible owing to conflicting magnetic field requirements. Combined advances in the epitaxial growth of a nitride superconductor with a high The unexpected discovery of the quantum Hall effect was the result of basic research on silicon field-effect transistors combined with my experience in metrology, the science of measurements. This personal review demonstrates that condensed matter physics is full of surprises and that access to excellent crystals and materials is a crucial ingredient of the success of experimentalists in The fractional quantum Hall effect (FQHE) on the other hand has been recognized very early as being due to the occurrence of new, strongly correlated, electronic ground states (see This article was done as a term paper for the course PH5107(Advanced Condensed Matter) at IISER Kolkata.

This is the famous Quantum Hall Effect4. The fundamental quantum of Hall resistance is h/e2 =25,813Ω. In this lab we will only be concerned with the Hall coefficient. 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. A collection of objects may assemble to form a Quantum Hall physics under applied potentials and Hawking-Unruh effect are the two such phenomena under consideration in this paper.

24 Apr 2012 The conventional quantum Hall effect is a particular example of the general relation if one views the electric field as a rate of change of the vector

“Quantum Spin Hall” state •It was actually invented by C. Kane and E. Mele in 2005 - they were thinking about the effect of spin-orbit coupling in graphene! •It has been experimentally conﬁrmed, but not in graphene. However, we can still use that example.

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.

The integer quantum Hall effect. Plotting the Hall resistance (essentially the reciprocal of the Hall conductance) of a low-temperature two-dimensional electron gas against the strength of the imposed magnetic field normal to the gas plane, one finds a stairlike quantized sequence of Hall conductances very precisely equal to ne 2 / h , where n is the integer that characterizes each plateau.

The spacing of these levels is proportional to the classical cyclotron frequency != eB m. Quantum Mechanics of Electrons in a Nobel Lecture: The fractional quantum Hall effect* Horst L.

Plotting the Hall resistance (essentially the reciprocal of the Hall conductance) of a low-temperature two-dimensional electron gas against the strength of the imposed magnetic field normal to the gas plane, one finds a stairlike quantized sequence of Hall conductances very precisely equal to ne 2 / h , where n is the integer that characterizes each plateau. Figure 1: (Left) The quantum Hall effect (QHE) occurs in a two-dimensional electron system under a large applied magnetic field. The transverse resistance (ρ x y) takes on quantized values while the longitudinal resistance (ρ x x) vanishes.
