1. The problem statement, all variables and given/known data A wavepacket, psi(x,t), can be expressed as a linear combination of eigenstates. Assuming that only 2 eigenstates, phi0(x) and phi1(x), contribute to the linear combination write down the expression for |psi(x,t)|^2. 2. Relevant equations [Boltzmann's constant = 1.38 x10^23 J /K, Planck's constant h = 6.626 x10 ^-34 J s, Gas constant R = 8.314 J K /mol] 3. The attempt at a solution I need help with how to start solving this problem.
