choose all of the following statements that are correct for a particle in a one dimensional infinite square

a,)the stationary states refers to eigenstates of any operator corresponding to physical observable

b)in an isolated system if a particle has well -defined position at time = 0 the position of the particle is well defined at all times t>0

Consider an electron in a one-dimensional potential well of width Lz in the z direction, with infinitely high potential barriers on either side (i.e., at z = 0 and z = Lz ). For simplicity, we assume the potential energy is zero inside the well. Suppose that at time t = 0 the electron is in an equal linear superposition of its lowest two energy eigenstates, with equal real amplitudes for those two components of the superposition. (i) Write down...
