| description | In this final year project thesis, I outline a method to calculate the reflection
probability induced by Feshbach resonance between the ground state
and the excited state of an atom in an atom surface potential. The eigenstates
and eigen-energies of the atom-surface potential are calculated using
the Wentzel-Kramers-Brillouin method. The reflection coefficient, as derived
from scattering theory, is then calculated with the integrals in the expression
solved numerically. An example calculation is performed to demonstrate the
method with the assumption that the optical field the atom experiences is
constant. |
