## Advanced Quantum Mechanics III

Here you will learn how to treat complex quantum systems with perturbation theory and how to describe many-body quantum systems with second quantization.

Derivation of allowed energies and associated wave functions inside and outside a one-dimensional finite potential box.

` $$ p ~=~ \frac{h}{\lambda} $$ `

` $$ [ L^2, \, L_j ] ~=~ 0 $$ `

Here you will learn how to determine energy of photons and how this energy depends on the color of light (frequency or wavelength).

` $$ \Delta \lambda ~=~ \lambda_{\text C} \, \left( 1 ~-~ \cos(\theta) \right) $$ `

` $$ \lambda ~=~ \frac{1}{R \, \left( \frac{1}{n^2} - \frac{1}{m^2} \right)} $$ `

` $$ W_{\text{mol}} ~=~ N_{\text A} \, h \, \frac{c}{\lambda} $$ `

Here you will learn what the photoelectric effect is, how it can be described with a Einstein formula + everything you need to know about it.

` $$ T ~=~ \frac{2897.8 \,\cdot\, 10^{-6} \, \mathrm{m} \mathrm{K}}{ \class{blue}{ \lambda_{\text{max}}} } $$ `

In this physics video you will learn what Hermitian operators and matrices are and what important properties they have.
