  3. Abstract:
  4. Resonating valence bond (RVB) states are suitable candidates for ground state of the Heisenberg model on various two dimensional lattices. When a singlet valence bond is broken to produce a triplet state, the resulting excitation is called a triplon. In this paper, we obtain formulas for the overlap and also matrix elements of si sjoperator between states with arbitrary number of triplons. Our results are valid for any 2D lattice
