Dynamical Diffraction Theory for Wave Packet Propagation in Deformed Crystals
Kei Sawada, Shuichi Murakami, Naoto Nagaosa
We develop a theory for the trajectory of an x ray in the presence of a crystal deformation. A set of equations of motion for an x-ray wave packet including the dynamical diffracti…

Topological nature of polarization and charge pumping in ferroelectrics
Shigeki Onoda, Shuichi Murakami, Naoto Nagaosa
Electric polarization or transferred charge due to an adiabatic change of external parameters is expressed in terms of a vector field defined in the space. This…
