Dipole Moments of Black Holes and String States
M. J. Duff, J. T. Liu, J. Rahmfeld
As a further test of the conjectured equivalence of string states and extremal black holes, we compute the dipole moments of black holes with arbitrary spin and superspin in D=4,N=…
Integrabilities of the long range t-J model of twisted boundary condition
J. T. Liu, D. F. Wang
The integrability of the one-dimensional long range supersymmetric t-J model has previously been established for both open systems and those closed by periodic boundary conditions…
Integrable SU(m|n) supersymmetric electronic models of strong correlations
James T. Liu, D. F. Wang
We generalize the SU(2|2) supersymmetric extended Hubbard model of 1/r2 interaction to the SU(m|n) supersymmetric case. Integrable models may be defined on both uniform lattice and…
Ground state and excitations of the extended Hubbard model
D. F. Wang, James T. Liu
We examine the ground state and excitations of the one dimensional extended Hubbard model with long range interaction. The ground state wavefunctions and low lying excitations are…
