Landau Levels in a Magnetic Field

This interactive simulator explores Landau Levels in a Magnetic Field in Chemistry. Charged particle in a uniform B-field: equally-spaced Landau ladder E_n = ℏω_c(n+½) with cyclotron frequency ω_c = qB/m, magnetic length ℓ_B = √(ℏ/qB) and orbit radius r_n = ℓ_B√(2n+1). Animated cyclotron orbit + linear-in-B fan diagram; the n_B = qB/h degeneracy underlies the quantum Hall effect. Use the controls to change the scenario; watch the visualization and any graphs or readouts to connect the model with lectures, labs, and homework.

Who it's for: For learners comfortable with heavier math or second-level detail. Typical context: Chemistry.

How it works

Landau levels of a 2-D charged particle in a perpendicular magnetic field B: the equally-spaced ladder E_n = ℏω_c(n+½), the magnetic length ℓ_B = √(ℏ/qB), the cyclotron radius r_n, and the linear-in-B fan diagram — the building block of the integer quantum Hall effect.
