Abstract
The Heisenberg model on a two-chain spin-1/2 ladder with frustrating s econd-neighbor interactions is studied by using series expansions abou t the Ising and dimer limits, numerical diagonalization, and by Abelia n bosonization analysis. The phase diagram is determined, and pair cor relations and the complete dispersion relations for the triplet spin-w ave excitations are also computed.
