Abstract
The density matrix approach is a technique to calculate the lowest eigenvalue of a large matrix such as occurring in quantum mechanical systems. So far the method works very well for systems with a linear structure. The limitations for a planar structure, from critical correlations and from slowdown, due to the existence of slow modes, will be discussed using the transverse Ising model as illustration.
