2. This problem will help you understand how two atoms can form a molecule through the process of chemical bonding. The physics behind the chemical bonding is very much the same as that discussed in energy splitting process to form energy bands in a macroscopic matter state where we have a lot of atoms involved but all atoms are nicely arranged to form a kind of periodic structure. In this problem, let's make things even simpler: we only consider two...

need help with this problem. please explain, thank you.
8. Consider a particle encountering a barrier with potential U = U, >0 between x = -a and x = a with incoming energy E > U. a) Write the symbolic wave functions before and after passing through the barrier (i.e., for xs-a and x>a; regions I and III). UN b) Write down the Schrodinger equation for the wave function in the middle (region II) where the potential is non-zero i.e.,...

1. Consider an electron in a 1-D box of length L = 1 nm that has energy eigenstates given by ºn(x) = 2sin(n7x) when x has units of nanometers. Now consider that an atomically-precise hammer is used to deform the bottom of the box such that the electron feels an effective potential given by (2) V(x) = V(x) = -2(x...
