What Does TDA Stand For?

TDA stands for Tamm Dancoff Approximation

The Tamm Dancoff Approximation (TDA) is a computational method used in quantum chemistry and many-body physics that simplifies the treatment of excited states within the context of linear response theory. By neglecting certain coupling terms in the excitation operators, TDA provides an efficient way to calculate excitation energies and transition properties while maintaining a balance between accuracy and computational cost. It is commonly applied in the study of electronic transitions in molecular systems and plays a crucial role in various quantum mechanical models.
