Spin Correlations around Mobile Holes in an Antiferromagnet

Abstract

Various spin correlation functions around a mobile hole in a two-dimensional antiferromagnetic state are calculated in the t-J model. The correlations show canted and twisted character at k=(0, 0) and (π⁄2, π⁄2), respectively, where the latter is the wave vector of the ground state. Possible spin configurations around the hole are discussed.
