In which field is the composite fermion concept applied?
Biology
Chemistry
Quantum Physics
Astronomy
Answer
The composite fermion concept, used in quantum physics, describes quasiparticles known as composite fermions, which arise when electrons in specific semiconductor structures interact strongly and effectively behave as new particles with fractional charge and statistics. These composite fermions help explain several observed phenomena in quantum Hall systems and provide insights into the behavior of strongly correlated electrons in condensed matter physics.
