Question

The potential energy of a harmonic oscillator is U = kx. Show that the expectation value (U)
of U is E0 / 2 when the oscillator is in the state n = 0. (In fact, this is true for all states of the harmonic
ocillator.) What is the expected value of the kinetic energy of the oscillator? How do these results
compare to the classical values of
Ū and KE ?

Consider a quantum particle with energy E approaching a potential barrier of width L and heightV0 > E from the right (as shown in image). The wavefunction of the particles in the region x > L is given by ψ = A exp {−i (kx + ωt)} , where A, k and ω are all constants. Use the Gamow factor formalism to calculate an approximate expression for the transmission rate of these particles through the barrier.
In a demonstration of the double slit experiment, a high velocity stream of dense spheres is fired at a slit , and another stream is fired at an adjacent identical slit. For each stream, all spheres pass straight through the slit, then hit the same location on a screen. Next, two streams of electrons are fired at two slits next to one another. On a screen beyond the slits, a diffraction pattern is formed. Which situation does classical mechanics explain, and which situation does quantum mechanics explain?

= = An electron having total energy E 4.60 eV approaches a rectangular energy barrier with U■5.10 eV and L-950 pm as shown in the figure below. Classically, the electron cannot pass through the barrier because E < U. Quantum-mechanically, however, the probability of tunneling is not zero. Energy E U 0 i (a) Calculate this probability, which is the transmission coefficient. (Use 9.11 x 10-31 kg for the mass of an electron, 1.055 x 10-34] s for h, and note that there are 1.60 x 10-19 J per eV.) (b) To what value would the width L of the potential barrier have to be increased for the chance of an incident 4.60-eV electron tunneling through the barrier to be one in one million? nm
The normalised wavefunction for an electron in an infinite 1D potential well of length 80 pm can be written:ψ=(0.587 ψ2)+(0.277 i ψ7)+(g ψ6). As the individual wavefunctions are orthonormal, use your knowledge to work out |g|, and hence find the expectation value for the energy of the particle, in eV.
