Abstract

We use a generalized Gutzwiller approximation elaborated to evaluate matrix elements with partially projected wave functions and formerly applied to homogeneous systems [N. Fukushima et al., Phys. Rev. B 72, 144505 (2005); B. Edegger et al., Adv. Phys. 56, 927 (2007)]. In the present paper we consider projected single-particle (hole) excitations for electronic systems with antiferromagnetic order and obtain the corresponding tunneling probabilities. The accuracy and the reliability of our analytical approximation is tested using the variational Monte Carlo method. Possible comparisons with experimental results are also discussed.
