Autumn School on Correlated Electrons:
DMFT – From Infinite Dimensions to Real Materials

17-21 September 2018, Forschungszentrum Jülich


Since the beginning of quantum mechanics, emergent many-body phenomena represent the grand-challenge in theoretical condensed-matter physics. Indeed, static mean-field approaches fail to capture even the simplest many-body effects, while diagrammatic techniques generally fail in the regime characteristic of strong correlations. The introduction of dynamical mean-field theory (DMFT) has revolutionized this field. Two insights paved the way to this paradigm shift. The first is that in the limit of infinite dimensions all contributions to the self-energy become local. The second is that the locality of the self-energy makes it possible to build a new type of mean-field theory, dynamical in nature, by mapping a correlated lattice problem onto a self-consistent quantum-impurity model. In the last decades, thanks to advances in model building combined with the development of flexible and numerically exact quantum-impurity solvers, DMFT was successfully linked with ab-initio density-functional techniques, making it the method of choice for the investigation of correlated electron materials.

This year's school will cover the most important aspects of the DMFT approach to real materials. Lectures will range from the basics to advanced topics, covering the DFT+DMFT method, non-local extensions of DMFT, advanced quantum impurity solvers, the calculation of dynamical response functions, and the description of correlation effects out of equilibrium.

The goal of the school is to introduce advanced graduate students and up to this modern method for the realistic modeling of strongly correlated matter.

General Information

Venue: The school will take place from 17 to 21 September 2018 at the Forschungszentrum Jülich, in the Lecture Hall of the Peter-Grünberg Institute, building 4.8, room 365.

Participation: The school is intended for advanced graduate or PhD students and postdocs in the field of electronic structure of materials.

Admission: Interested students should apply before May 31, 2018 through the registration form. Accepted applicants will be informed via e-mail two weeks after the deadline for applications.

Accommodation: Students can apply for financial support to cover accommodation costs. Participants supported by the school will be accommodated in the Aachen Youth Hostel. Funding for accommodations is limited.

ICAM Junior Travel Awards: We might be able to provide a limited number of ICAM Junior Travel Awards. Eligible candidates can apply. For more information see the ICAM site and the registration form.

Transport: A shuttle bus will be operating in the mornings and evenings between the Youth Hostel in Aachen and the Forschungszentrum Jülich. The bus will leave in the morning at 7:45 from the Busparkplatz at Aachen Jugendherberge. There will also be a shuttle from Jülich, leaving at 8:30 in front of Hotel am Hexenturm.

Hotels in Aachen and Jülich: Participants for whom no low-cost accommodation can be found or who wish to stay in a hotel may find hotels at these web-sites: Jülich and Aachen.
