Quantum Hall Systems ― Braid Groups, Composite Fermions and Fractional Charge

Discovered some 20 years ago with a Nobel Prize awarded in 1985 for work in this intriguing area of condensed matter physics, many unanswered questions remain about quantum Hall effects. Jacak and his colleagues (physics, U. of Technology, Wroclaw, Poland) treat some important topics in theory of the physics of quantum Hall effects for physicists and graduate students in the field. They pay particular attention to the fractional quantum Hall effect (as vs. the integer one) and its relationship with the topology of planar systems.
