What Do You Know About The Quantum Hall Effect? - Quiz

The quantum Hall effect (or integer quantum Hall effect) is a quantum-mechanical version of the Hall effect that's subjected to low temperatures and strong magnetic fields. As a result, the Hall conductance undergoes quantum Hall transitions in other to take on the quantized values. This quiz is to test how deep and accurate your knowledge on quantum Hall effect is.
