Hi, jostpuur and alxm. Thank you for your answers. Yes, I've realized that the wavefunction was unacceptable in physics if Re(E) < 0 or Im(E) is not 0. But in my opinion, all concepts of eigenvalue, eigenfunction and Hermitian operator are defined in mathematics. So one can always solve the...

Hi, there. It should be yes, but I'm very confused now. Consider a simple one-dimensional system with only one particle with mass of m. Let the potential field be 0, that's V(r) = 0. So the Hamiltonian operator of this system is: H = -hbar^2/(2m) * d^2/dx^2 \hat{H} =...
