AWhat changed
Computed and visualized the self-similar single-band spectrum against magnetic flux per lattice cell.
Scientific scope
The record is Hofstadter's sole-author 1976 Physical Review B paper and its single-band model. It does not absorb earlier magnetic-band work, later experimental observations, quantum Hall measurements or every model now called a Hofstadter butterfly.
