Density Matrices

Density Matrices is a theoretical construct in quantum mechanics that represents the statistical state of a quantum system within the framework of Density Functional Theory, distinguished from wavefunction-based descriptions by its ability to describe mixed states and incorporate electron correlation effects through a positive semi-definite, Hermitian matrix encoding the probability amplitudes of the system's density.
