Landau Level

Landau Levels are discrete energy levels that electrons can occupy when they are subjected to a strong magnetic field. In this situation, instead of moving freely, the electrons spiral around the magnetic field lines, creating quantized orbits. Each orbit corresponds to a specific energy level, much like how planets orbit the sun at defined distances. This phenomenon is important in quantum mechanics and is observed in materials like graphene and in the study of phenomena like the quantum Hall effect, helping us understand the behavior of electrons in extreme conditions.
