Query: A hydrodynamic approach to electron beam imaging using a Bloch wave
  representation   Calculations of propagating quantum trajectories associated to a wave
function provide new insight into quantum processes such as particle scattering
and diffraction. Here, hydrodynamic calculations of electron beam imaging under
conditions comparable to those of a scanning or transmission electron
microscope display the mechanisms behind different commonly investigated
diffraction conditions. The Bloch wave method is used to propagate the electron
wave function and associated trajectories are computed to map the wave function
as it propagates through the material. Simulations of the two-beam condition
and the systematic row are performed and electron diffraction is analysed
through a real space interpretation of the wave function. In future work, this
method can be further coupled with Monte Carlo modelling in order to create all
encompassing simulations of electron imaging.
