Kapitza-Dirac diffraction without standing waves: diffraction without a grating?
نویسندگان
چکیده
We discuss electron diffraction from two counterpropagating light waves with two different frequencies. We show that, even though these waves do not form a standing wave, electron diffraction similar to the conventional Kapitza-Dirac effect, i.e., scattering on a standing wave, is still possible. The nonlinear response of the electron to the laser fields creates a stationary diffraction grating from which the same electron scatters.

Theory of the Kapitza-Dirac diffraction effect.
We treat the Kapitza-Dirac diffraction effect observed recently by Batelaan et al. using a newly developed nonperturbative quantum-field scattering theory. Our theory shows that an electron beam passing perpendicularly through a focused standing light wave can produce diffraction patterns. Our theory predicts (1) the minimum value of the ponderomotive energy is (Planck's over 2 pi omega)(2)/m(e...
متن کاملSpin dynamics in the Kapitza-Dirac effect.
Electron spin dynamics in Kapitza-Dirac scattering from a standing laser wave of high frequency and high intensity is studied. We develop a fully relativistic quantum theory of the electron motion based on the time-dependent Dirac equation. Distinct spin dynamics, with Rabi oscillations and complete spin-flip transitions, is demonstrated for Kapitza-Dirac scattering involving three photons in a...
متن کاملCoherent manipulation of atoms with standing light waves
Coherent manipulation of atomic momentum states is the primary goal of atom optics, and the standing light wave with its associated stimulated light forces is the primary method of achieving this goal. A description of the standing wave as two counter-propagating beams of photons leads to a natural explanation of Bragg scattering. In contrast, Kapitza–Dirac scattering, atom lithography, and the...
متن کاملDiffraction of 0.5keV electrons from free-standing transmission gratings.
A nanostructured grating was used to diffract a low-energy (500 eV) electron beam, and the current transmitted into the zeroth diffraction order was greater than 5% of the incident beam current. This diffraction efficiency indicates that the 55-nm-wide grating bars absorb electrons but the 45-nm-wide slots between bars transmit electron de Broglie waves coherently. The diffraction patterns can ...
متن کاملBragg scattering of free electrons using the Kapitza-Dirac effect.
Bragg scattering has been observed for free electrons using a standing wave of light. Both the rocking curve and the angular electron distribution have been measured. The results of a numerical simulation to the Schrödinger equation are consistent with our experimental data. Unlike the diffraction regime which uses thin crystals, the Bragg regime requires the use of thick crystals. We point out...
