SUMMARY
Density Matrix Renormalization Group (DMRG) theory is primarily effective for one-dimensional systems due to its inherent structure. Generalizations to higher dimensions exist through the use of matrix product states and tensor networks, such as the Multiscale Entanglement Renormalization Ansatz (MERA). Relevant literature includes arXiv papers 1008.3477v2, 1308.3318, and 1306.2164, which discuss these advancements. Additionally, the Heisenberg Hamiltonian can be approached using these methods, as explored in arXiv paper 1405.3259.
