PhD Position at the ESRF: Calculating RIXS spectra of highly-correlated electron materials



A major experimental effort at the European Synchrotron Radiation Facility (ESRF; Grenoble, France) is devoted to using resonant inelastic x-ray scattering (RIXS) to uncover the fundamental pairing mechanism in high-Tc superconductors. The parent compounds of the copper-oxide based superconductors exhibit antiferromagnetic ordering at low temperature and it is believed that low energy spin excitations play an important role in the superconducting state. RIXS should lead to significant insights into the fundamental behaviour of high-Tc materials.
Description of thesis work:
The objective of this thesis project is to extend the computational capability to calculate resonant inelastic x-ray scattering spectra (RIXS) by including interactions between the core-excitation and bosonic modes including phonons and magnons. This will be done within the context of an existing code that can already generate basic RIXS spectra [Phys Rev B 83, 115106 (2011)]. This code takes a first-principles description of the ground-state and treats electronic excitations within many-body perturbation theory (MBPT). Tasks involve the implementation of formalism that has previously been demonstrated on simple electron gas models, but new descriptions of electron-magnon scattering at the MBPT level may need to be derived.
The candidate for this position should have a strong background in theoretical condensed matter physics as well as experience and interest in programming (fortran & scripting languages).
Application details:
You should hold a degree in Physics or Chemistry allowing enrollment for a PhD, such as an MSc, Master 2 de Recherche, Laurea or equivalent. Further information on the post can be obtained from Keith Gilmore (tel.: +33 (0)4 76 88 17 27, email: kgilmore@esrf.fr). For further information on employment terms and conditions, please refer to http://www.esrf.fr/Jobs/Conditions. The ESRF is an equal opportunity employer and encourages applications from disabled persons.
Apply on-line at http://www.esrf.fr/Jobs under job reference # CFR404.
Application deadline 26 August 2015.

Postdoctoral positions in computational materials science

Two postdoctoral positions in computational materials science are available at the Max Planck Institute for Polymer Research, Mainz in the Theory Department, group of Denis Andrienko ( http://www.mpip-mainz.mpg.de/~andrienk/ ). The research project concerns combining atomistic simulations and quantum modeling of charge/exciton transport properties of organic light emitting diodes. The project is funded by European Union and is a part of a broad collaboration of nine industrial and academic partners. The initial contract will be for one year, with possible renewal for up to three years. Applicants should hold a PhD degree and have a strong background in physics, physical chemistry, or theoretical chemistry. Experience in programming (C++) is essential. Interested scientists should send an application, a CV, and recommendation letters electronically to Dr. Denis Andrienko ( denis.andrienko@mpip-mainz.mpg.de ).  http://psi-k.net/jobs/postdoctoral-positions-in-computational-...
