The fundamental idea is to replace the electrons of a molecule with a simpler system that is efficient to simulate yet has rich physics, such as a quantum harmonic oscillator (know as a Quantum Drude Oscillator).\r\n\r\nThis technique has two main advantages: the model is parameterised from the properties of isolated molecules and its dynamics can be sampled using an order N method.
