| Muhtasari≠ | Density Matrix Renormalization Group (DMRG) is a powerful computational method for solving strongly correlated quantum systems, particularly one-dimensional lattice models and quantum chemistry problems. Introduced by White in 1992, DMRG uses a variational approach and tensor-network representation to efficiently describe quantum ground states and excitations, achieving numerical accuracy competitive with exact diagonalization for systems that other methods cannot treat. | X-ray Absorption Near Edge Structure (XANES) is a synchrotron X-ray spectroscopy technique that measures the electronic and geometric structure around a specific atom by analyzing the X-ray absorption spectrum within about 50 eV of an absorption edge. Developed by Lee and Pendry in 1975, XANES is complementary to EXAFS and reveals valence state, local symmetry, and unoccupied orbital structure through near-threshold features and resonances. |
