Matlab code |
| bf_mat.m |
Calculates matrix representation of the Hofstadter Hamiltonian in rational case. This
function is used in bf_dbase.m and bf_dbase2.m. |
bf_dbase.m
bf_dbase2.m |
Calculate and store a database of eigenvalues of the Hofstadter Hamiltonian. The calculated eigenvalues
correspong to the edges of the energy bands. See inside the function code for details. |
| bf_db2bw.m |
Creates a black&white TIF image of the spectrum from the eigenvalues database. |
| bf_db2tif.m |
Creates a color TIF image of the spectrum gaps from the eigenvalues database. |
