Hi everyone, I need help for preparing a Hamiltonian matrix. What will be the elements of the hamiltonian matrix of the following Schrödinger equation (for two electrons in a 1D infinite well): -\frac{ħ^{2}}{2m}(\frac{d^{2}ψ(x_1,x_2)}{dx_1^{2}}+\frac{d^{2}ψ(x_1,x_2)}{dx_2^{2}}) +...

Hello, I am new here. I hope I am posting my problem at the right place. I need some urgent help regarding the following differential equation: A\frac{d^{2}y}{dx^{2}}+B\frac{dy}{dx}=f(x,\lambda)...(1) where, A and B are constants. x and \lambda are independent. I have solved...
