Autumn School on Correlated Electrons:
Correlations and Phase Transitions

16-20 September 2024, Forschungszentrum Jülich

Announcement: Poster and Flyer

Scope

Emergent phenomena are the essence of condensed-matter physics and at the same time what makes the behavior of correlated materials appealing for applications. They are, however, hard to understand at a fundamental level. It is the interplay of several competing interactions — none of which can be treated as a mere perturbation, leading to the emergence of effective interactions — that makes their description a grand challenge. Addressing this problem requires mastery of a wide spectrum of theoretical concepts, ranging from materials modeling using first-principles approaches to advanced many-body methods based on dynamical mean-fields, stochastic simulations and renormalization techniques. The concepts of symmetry, topological invariance and the classification of transitions between phases are of crucial importance to bring order to the plethora of observed phenomena.

The goal of this year’s school is to provide students with an overview of the state-of-the-art in the field of emergent phases in strongly correlated systems and the many techniques used to investigate them. The program will start with fundamental models and concepts, introducing the Hubbard and Anderson Hamiltonians and their physics, and providing an overview of field-theoretical aspects of condensed-matter physics. More advanced lectures will introduce symmetries, Berry phases and topological quantum matter. The focus will then turn to emergent phenomena: superconductivity, conventional and non-conventional, Kondo and heavy-fermion behavior, Kosterlitz-Thouless transitions, Mott phases, orbital-ordering, and quantum phase transitions. The topics will be treated both from the view point of simple models and that of real materials, with an outlook on materials design from the theoretical and experimental viewpoint. The theoretical approaches covered will go from density-functional-theory-based methods to dynamical mean-field theory and quantum Monte Carlo. Experimental lectures will cover phenomena under normal and extreme conditions.

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, 2024 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 Cologne-Deutz Youth Hostel. Funding for accommodations is limited.

ICAM Junior Travel Awards: Eligible candidates can apply for an ICAM Junior Travel Award. Funding is limited to about 10 students. 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 Cologne and the Forschungszentrum Jülich. The bus will leave in the morning from Jugendherberge Köln-Deutz. There will also be a shuttle from Jülich, from Stadthotel Jülich.
