摘要
The 2D quantum Heisenberg antiferromagnet at zero temperature with two kinds of locally frustrating defects ferromagnetic bonds and impurity spins - is studied. An analytic approach is developed to investigate strong defect-environment couplings. Results for the local ground state properties are compared to numerical simulations and previous work.
