  4. Diffusion Monte Carlo Methods and Trial Function

    For complex quantum system, the variation method is no longer useful for tho solve the problem precisely, you need a basis set of quite a large size. Quantum simulation is used in such system. Monte Carlo Method is widely used.

    Recently I began to learn about these methods. Notice that …
