Why would CCSD and FCI give the same PES? Would you expect this result if the same calculations were performed on the water molecule? Hint: The CCSD methods includes only single and double electron excitations, whereas full CI (FCI) accounts for electron excitations from all electrons simultaneously and therefore finds the true solution of the Schrödinger equation

Techniques and applications of quantum theory

Quantum theory, often known as quantum physics, is the foundation of modern physics and encompasses the nature and behavior of matter and energy at the atomic and molecular levels. As the exact nature and behavior of atomic and subatomic particles are impossible to determine, the laws of classical physics do not apply to this discipline. As a result, quantum field theory is primarily based on assumptions and probabilities.
