Abstract
In these notes we review both the formulation and some applications of the density matrix renormalization group (DMRG). We illustrate the use of DMRG with applications to ladder systems. We first consider Heisenberg ladders, which exhibit an interesting odd-even alternation of behavior as the number of chains increases. We then consider the behavior upon doping, using the t-J model. A simple theoretical framework is developed to explain why holes bind in pairs in two-dimensional antiferromagnets.

If it turns out that the staggered order is lower in energy, then the ground state has staggered order and there is still binding of defects because of the induced resonating order between the defects.
