Undergrad Computing determinants: Allowed shortcuts?
I had a question about computing determinants and just was wondering what was allowed. So I know that for an n x n matrix, you can go across a row and choose the matrix element as your determinant coefficient for the (n-1) x (n-1) determinant and you go across the row and do this until you're...- MrMultiMedia

Graduate Stationary States and time-independent states (aren't they the same?)
I always thought they were the same, but now I am reading a question that says "which of he following time-independent functions describe stationary states of the corresponding quantum systems?" Is there something I am missing? It's written like there is something to solve, but to me it seems...- MrMultiMedia

Undergrad Infinitesimals in integration vs delta x in summations
Hi, I first had a question regarding infinitesimals. What does it mean when the infinitesimal is at the beginning of the integral? For example: ∫dxf(x) is this the same as ∫f(x)dx ? My second question was how to convert a summation to an integral and a summation into an integral...- MrMultiMedia

Undergrad Magnetic Field Orbital Splitting
Hi friends. I'm doing a homework problem about how degenerate orbitals split in the presence of a magnetic field. I understand everything, but I was just had a question about notation. ΔE, the energy between degenerate orbitals in a magnetic field equals μB = (e*hbar/2m)B I was just...- MrMultiMedia

Graduate The radial schrodinger equation
Oh you're right. They do. But not for the 1s level. So in the case of that problem I didn't have to worry about second derivatives.- MrMultiMedia

Graduate The radial schrodinger equation
Ok, I found a simple definition in terms of a0 for the radial wave function in the textbook. It was in one of the examples, but not explicitly shown in the main text, so it took some extra searching. I used: dP = (4(r^2)*e^(-2r/a0))/a0^3dr and solved for dP/dr. After that I just had to...- MrMultiMedia

Graduate The radial schrodinger equation
There is no table in the textbook. I think need to find P(r) and find the maximum. There's no simpler way to solve the radial Schrödinger equation?- MrMultiMedia

Graduate The radial schrodinger equation
Hi, I'm doing a homework problem in my modern physics class and I'm stuck at a point. The question is "Show that the radial probability density of the 1s level in hydrogen has its maximum value at r = a0, where a0 is the Bohr radius" I know that the radial Schrödinger equation will...- MrMultiMedia
