WebbThis course teaches commonly used approximation methods in quantum mechanics. They include time-independent perturbation theory, time-dependent perturbation theory, tight binding method, variational method and the use of finite basis set. In each case, a specific example is given to clearly show how the method works. WebbA method of finite differences is employed to solve the system of 2 identical fermions that don’t interact with each other to plot the wavefunction and probability density curves. Next, perturbation theory is applied to find the correction to the energies and wavefunctions in order to account for potential due to the repulsion between the two electrons in addition …
