摘要：

The quantum Heisenberg chain with Dzyaloshinsky-Moriya interactions is solved by relating it to the XXZ Hamiltonian with a certain type of boundary conditions. Several properties of the ground state are derived which agree with the intuition derived from related soluble classical models. Implications to the model of known results from the theory of conformal invariance, as well as generalizations to higher spin, are briefly discussed. © 1990 Plenum Publishing Corporation.
