The Fractional Quantum Hall Effect (FQHE) is a quantum phenomenon observed in two-dimensional electron systems subjected to low temperatures and strong magnetic fields. It is a refinement of the Quantum Hall Effect (QHE), where the Hall conductance quantizes to fractional values, unlike the integer values seen in QHE. This effect is a manifestation of the complex interactions between electrons, leading to the formation of exotic quasi-particles with fractional charge.
