A naive distinction between metals and insulators rests on the single-electron picture: completely filled or empty bands characterize insulators while metals have some partially filled bands. Nature, however, offers a much richer variety of behaviors: Mott insulators would be band metals in the absence of electron correlation while strongly-correlated metals behave quasiparticle-like only in the Fermi-liquid regime. Correlated metals and insulators can be distinguished by the gap in the spectral function. Superconductors form a class of their own, they have a single-electron gap but are not insulators.
This year’s school addresses the rich physics of correlated insulators, metals, and superconductors. Insulators show complex ordering phenomena involving charge, spin, and orbital degrees of freedom. Correlated metals exhibit non-Fermi-liquid behavior except right at the Fermi surface. Superconductors are dominated by the delicate interplay of coupling bosons and quasiparticles. Along with the phenomena, the models and methods for understanding and classifying them will be explained.
The aim of the school is to introduce advanced graduate students and up to the modern approaches for modeling strongly correlated materials and analyzing their behavior.
Venue: The school will take place from 25 to 29 September 2017 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, 2017 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.
