A Dynamic 'Double Slit' Experiment in a Single Atom
A single-atom 'double-slit' experiment is realized by photo-ionizing Rubidium atoms using two independent low power lasers. The photoelectron wave of well-defined energy recedes to the continuum either from the 5P or 6P states in the same atom, resulting in two-path interference imaged in...

| description | A single-atom 'double-slit' experiment is realized by photo-ionizing Rubidium
atoms using two independent low power lasers. The photoelectron wave of
well-defined energy recedes to the continuum either from the 5P or 6P states in
the same atom, resulting in two-path interference imaged in the far field using
a photoelectron detector. Even though the lasers are independent and not phase
locked, the transitions within the atom impart the phase relationship necessary
for interference. The experiment is designed so that either 5P or 6P states are
excited by one laser, before ionization by the second beam. The measurement
cannot determine which excitation path is taken, resulting in interference in
wave-vector space analogous to Young's double-slit studies. As the lasers are
tunable in both frequency and intensity, the individual excitation-ionization
pathways can be varied, allowing dynamic control of the interference term.
Since the electron wave recedes in the Coulomb potential of the residual ion, a
quantum model is used to capture the dynamics. Excellent agreement is found
between theory and experiment. |
