Covers the expenses of part of the lectures of the event as well as local activities of the school



Description


The School aims at giving a unified overview of the three
many-body approaches, GW methods, quantum Monte Carlo methods and
dynamical mean field theory. It will give a solid introduction
to the description of electronic correlation effects in both weakly and strongly correlated materials using these ab-initio many-body approaches. The School will provide the necessary
background and context, highlighting the
most challenging problems, and the topics of current interest.
Finally, the program will try to achieve a good balance
between theoretical and experimental lectures. The School will reach out to young researchers already
working in the general field of many-body ab-initio theory,
as well as researchers who are not yet practitioners but are
interested in acquiring the necessary expertise.



The School is supported by the European Science Foundation (ESF) Marie
Curie Series of Events Programme "Psi-k Training in Computational
Nanoscience", the ESF Nanoquantas Network of Excellence "European
Theoretical Spectroscopy Facility (ETSF)", the ESF Programme "Towards Atomistic Materials Design (Psi-k)", the Donostia
International Physics Center (DIPC), the Ministero de Educacion
y Ciencia and the National Science Foundation (NSF).
The School is part of the summer courses of the University of the
Basque Country
(
http://www.sc.ehu.es/scrwwwsu/index.htm
).




European Credit Transfer units for the course:



We will use the European Credit Transfer (ECT) system to express the work load of the School: One European Credit corresponds
to a work load of 25-30 hours including preparation. Therefore,
a certificate of 2 ECTs will be given to all PhD and master students who have successfully participated in the School.



Applications and financial support:



All those who wish to participate should fill in the application form,
including the request for financial support.
The accepted participants and the students who will receive financial support will be automatically notified through
the web page.



Accomodation:

Scientific Objectives

Program:



The program will consist of 6 hours of lectures per day. Ample
time will be given to informal discussions and interaction between
students and teachers, including round tables
addressing questions by the participants as well as
highlighting new frontiers in the field.
The list of covered topics is:



  • Basics of density functional theory (DFT) and time-dependent DFT
    (TDDFT); applications of DFT and TDDFT to complex systems.
  • New experimental techniques for excitation spectrum of materials.
  • Many-body theory in a nutshell; many-body perturbation
    theory (MBPT) and Hedin equation (GW method); applications of GW methods.
  • Introduction to the physics of correlated materials (theory and experiments):
    Mott transitions, Hubbard bands, Kondo systems, f-electron physics.
  • Basics of Quantum Monte Carlo methods and their
    application to real materials.
  • Introduction to DMFT and LDA+DMFT scheme; DMFT impurity solver and practice of LDA+DMFT.
  • f-electrons materials and the SIC method.

  • Combining the best of different worlds: MBPT-GW-DMFT and TDDFT
