Postdoc in applied mathematics or theoretical physics

We are delighted to offer a postdoctoral positions in the field of the interaction of x-ray radiation with matter, with the goal of developing new strategies for combining coherent x-ray diffraction and x-ray spectroscopy in a unified approach. The offered theoretical, computational project will be at the boundary of physics, chemistry and applied mathematics.

The position

  • Developing unified representation of elastic x-ray scattering and x-ray emission spectroscopy based on an appropriate electronic orbital representation
  • • Developing theoretical methods and numerical algorithms to solve for the direct inversion of the x-ray diffraction data under the constraints, given by x-ray emission spectra
  • • Generating high resolution electron-density maps and x-ray emission spectra by usage of state-of-the-art quantum chemistry codes
  • • Testing different algorithms on numerically generated diffraction and spectral data
  • •Proof of concept on experimental data

• University degree in a relevant subject and PhD in physics, physical or theoretical chemistry, or applied mathematics
• Background in theoretical atomic, molecular and optical physics, quantum chemistry, theoretical x-ray crystallography, applied mathematics or
related fields
• Experience in one or several of the following areas is highly desirable: numerical physics, development of quantum chemistry codes, theoreti-
cal x-ray spectroscopy, electronic structure calculations, theoretical x-ray crystallography, inverse problems, nonlinear optimization
• Strong record and interest in programming and code development in C++, C or Python is expected
• Excellent command of spoken and written English
