 | Wu, Yong-Shi | Quantum group, Bethe ansatz equations, and Bloch wave functions in magnetic fields | The wave functions for a two-dimensional Bloch electron in uniform magnetic fields at the mid-band points are studied by exploiting a connection to the quantum group Uq(sl2): A linear combination of its generators gives the Hamiltonian. We apply both analytic and numerical methods to obtain and an... | Bloch electron | 1996-04 |

 | Wu, Yong-Shi | Explicit solutions of the Bethe ansatz equations for Bloch electrons in a magnetic field | For Bloch electrons in a magnetic field, explicit solutions are obtained at the center of the spectrum for the Bethe ansatz equations of Wiegmann and Zabrodin. When the magnetic flux per plaquette is 1/(Q with Q an odd integer, distribution of the roots of the Bethe ansatz equation is uniform except... | Bloch electron; Magnetic flux | 1994-08 |
