Editing Fractional quantum Hall effect (section)

{{short description|Electromagnetic effect in physics}}
The '''fractional quantum Hall effect''' (fractional QHE or '''FQHE''') is the observation of precisely quantized plateaus in the [[Quantum Hall effect|Hall conductance]] of [[Two-dimensional electron gas|2-dimensional (2D) electrons]] at [[Decimals|fractional values]] of <math>e^2/h</math>, where ''e'' is the [[electron charge]] and ''h'' is the [[Planck constant]]. 
At the same time, longitudinal resistance drops to zero (for low enough temperatures) as for the [[Quantum Hall Effect|integer QHE]].
It is a property of a collective state in which electrons bind magnetic flux lines to make new [[quasiparticle]]s, and [[excited state|excitations]] have a [[fractionalization|fractional]] [[elementary charge]] and possibly also fractional statistics. The 1998 [[Nobel Prize in Physics]] was awarded to [[Robert Laughlin]], [[Horst Störmer]], and [[Daniel Tsui]] "for their discovery of a new form of quantum fluid with fractionally charged excitations".<ref>{{Cite web|url=https://www.nobelprize.org/nobel_prizes/physics/laureates/1998/|title=The Nobel Prize in Physics 1998|website=www.nobelprize.org|access-date=2018-03-28}}</ref><ref name=ptoday1998>{{cite journal|last=Schwarzschild|first=Bertram|title=Physics Nobel Prize Goes to Tsui, Stormer and Laughlin for the Fractional Quantum Hall Effect|journal=Physics Today|year=1998|volume=51|issue=12|doi=10.1063/1.882480|url=http://www.physicstoday.org/resource/1/phtoad/v51/i12/p17_s1|archive-url=https://archive.today/20130415185712/http://www.physicstoday.org/resource/1/phtoad/v51/i12/p17_s1|url-status=dead|archive-date=15 April 2013|access-date=20 April 2012|bibcode=1998PhT....51l..17S|pages=17–19}}</ref> 
The microscopic origin of the FQHE is a major research topic in [[condensed matter physics]].
