The fractional quantum Hall effect is a quintessential collective state of electrons, which has produced a plethora of remarkable new concepts. I will begin with an introduction to composite fermions, topological bound states of electrons and quantized vortices, and illustrate how their emergence provides a natural explanation for the prominent phenomenology of the fractional quantumContinue reading "Prof. Jainendra K.
