International Seminar and Workshop on
Strong Correlations and Angle-Resolved Photoemission Spectroscopy
April 10 - May 11, 2007
Scientific Coordinators:
Konrad Matho (CRNCS Grenoble, France)
Philipp Aebi (Université de Neuchâtel, Switzerland)
Daniel S. Dessau (University of Colorado at Boulder, USA)
Michael Potthoff (Universität Würzburg, Germany)
Organisation:
Claudia Poenisch (MPI PKS Dresden, Germany)
The CORPES07 workshop and seminar is situated at the crossing between
many-body theory for correlated electrons and angle-resolved
photoemission spectroscopy (ARPES). The ARPES experiment, based on a
detailed exploitation of the photoelectric effect in the immediate
vicinity of the Fermi edge, allows to measure the complex self-energy
function of correlated electrons. Many-body theory in this
non-perturbative regime can only progress in close comparison to
experimental data. One important objective is to understand the
behaviour of quantum matter characterised by electronic correlations so
strong that the low-lying excitations can no longer be described in
terms of quasi-particles.
The workshop will capture the instantaneous state of the art, two years
after CORPES05 (see: http://www.mpipks-dresden.mpg.de/~corpes05). New
topics on the experimental side include: photon sources from lasers (10
eV range) and soft X-ray beam lines (1 keV range) combined with new
high-resolution analysers, exploitation of photon and spin polarisation,
photoemission from nano-sized objects, quantum wells and vicinal
surfaces, possibilities with the free electron laser (FEL) as outlook
into the near future. New topics on the theory side include: progress in
solving polaronic problems, new routines for calculating the momentum
dependence of the self-energy, non-Fermi-liquid models beyond the
Luttinger liquid, applicable in space dimension D>1. Progress on
cuprates, cobaltates, manganates, etc., as well as on 4f and 5f systems,
will be reviewed.
The seminar will focus on current difficulties with the theoretical
interpretation of ARPES data and the proposed solutions to overcome
these difficulties. Main topics are: Inclusion of correlation effects
into one-step models, characterisation of the effect of electron-boson
couplings on the self-energy, connection between ARPES and other
experiments, low-dimensional systems, revision of the sudden
approximation in the regime of low photon energies, revision of
multi-photon processes. CORPES07 will also have an exploratory role in
view of creating a CORPES network, focused on developing software for
ARPES data analysis.
