Previously it was long believed that the symmetry breaking theory could explain all the important concepts and essential properties of all forms of matter. According to this view the only thing to be done is to apply the symmetry breaking theory to all different kinds quanten hall effekt phases and phase transitions.

Different FQH states all have the same symmetry and cannot be described by symmetry breaking theory. The contributors are renown scientists and leading authorities in several different fields.

Fractional quantum Hall effect

The fractional states of the electrons are understood as the integer QHE of composite fermions. Composite fermions have been observed, and the theory has been verified by experiment and computer calculations.


quanten hall effekt Fractionally charged quasiparticles are neither bosons nor fermions and exhibit anyonic statistics.

Unter Quanten-Hall-Bedingungen ist die Existenz sogenannter kompressibler und inkompressibler Streifen innerhalb der Randverarmungszone des 2DES vorhergesagt worden, die sich entweder metallisch oder isolierend verhalten quanten hall effekt damit die Hall-Potentialverteilung innerhalb des 2DES beeinflussen.

A striking model of much interest in this context is the Azbel—Harper—Hofstadter model whose quantum phase diagram is the Hofstadter butterfly shown in the figure.

Quantum Hall effect - Wikipedia

The vertical axis is the strength of the magnetic field and the horizontal axis is the chemical potentialwhich fixes the electron density. The vertical axis quanten hall effekt the strength of the magnetic field and the quanten hall effekt axis is the chemical potentialwhich fixes the electron density.

The colors represent the integer Hall conductances.
