Q: Is sound a classical mechanic phenomenon or is it quantum effect?

user6760Just curious because sound are longitudinal waves meaning the energy is passed from one particle to another nearby particle and produces a wave that continues on until it reaches our ear as sound wave or hits our skin as pressure wave, so is this consider quantum because of atoms and molecules?

Q: Combining two 1D Hamiltonians: How to construct the new Hamiltonian properly?

Hans WurstLets say I have two 1D Hilbert spaces $\mathcal H_A, \mathcal H_B$, for example two 1D harmonic oscillators. Each space comes with an orthonormal basis $B_A=\{\phi^A_n \}, \ B_B=\{\phi^B_m \}, \ n,m\geq 0$ where each function is a eigenfunction of the respective 1D-Hamilton operator. Now I'd like...
