Bloch electron in a magnetic field and the Ising model
I. V. Krasovsky
The spectral determinant det(H-εI) of the Azbel-Hofstadter Hamiltonian H is related to Onsager's partition function of the 2D Ising model for any value of magnetic flux Φ=2πP/Q thr…

Bethe ansatz for the Harper equation: Solution for a small commensurability parameter
I. V. Krasovsky
The Harper equation describes an electron on a 2D lattice in magnetic field and a particle on a 1D lattice in a periodic potential, in general, incommensurate with the lattice pote…
