History

Historical Context

The introduction of quantum mechanics in the early 20th century, particularly Niels Bohr's 1913 atomic model, transformed the understanding of atomic interactions. By 1930, advancements like the Fermi golden rule enabled precise calculations of energy transitions. Today, techniques such as Non-Equilibrium Green's Function build on these principles, highlighting the enduring impact of quantum mechanics in spectroscopy and modern scientific research.
