Entanglement and its role in nonequilibrium quantum dynamics
Viktor Eisler

Entanglement is one of the most characteristic features of quantum mechanics and plays a crucial role in understanding the low-temperature physics of quantum many-body systems. In the last two decades, the study of entanglement properties has become a leading direction within man ... more

From measures to machine learning: principled computation in big spaces
John Skilling, Maximum Entropy Data Consultants Ltd, ex University of Cambridge, England (Department of Applied Mathematics and Theoretical Physics)

The common feature of the frontier of modern science is the study of complex phenomena with large datasets that require substantial computation. How can that best be done, in a principled and effective manner? The foundation of quantification is the sum rule: if a system has pa ... more

Applied Research at Joanneum Research MATERIALS: Selected Topics of Nanotechnologies, Surface Technologies and Photonics
Paul Hartmann, Institute for Surface Technologies and Photonics, Joanneum Research Weiz

Modern printing and imprint processes enable large-area, flexible and cost-effective production of a large number of functional components with sensory, electronic or optical functions. The field of printed optics and electronics is in general no longer limited to research, but i ... more

Halide Perovskite Nanocrystals: From Platelets to Supercrystals
Jochen Feldmann, Chair for Photonics and Optoelectronics, Nano-Institute Munich Ludwig-Maximilians-Universität (LMU)

The optical properties of metal halide perovskite nano-platelets with controllable thickness down to one monolayer will be discussed. Pronounced quantum confinement effects, large excitonic binding energies and comparably high radiative recombination rates have been found, all de ... more

Coherence in time- and angle-resolved photoemission
Dr. Luca Castiglioni, Department of Physics, University of Zurich, Switzerland

Photoemission is fundamentally a coherent process. In most spectroscopic methods, however, the measured quantity is an intensity, i. e. the squared modulus of a complex amplitude. Some special techniques though are phase-sensitive and provide access to additional information. RAB ... more

Dielectric and magnetic behavior of pure and doped clusters
Rolf Schäfer, Eduard-Zintl-Institut für Anorganische und Physikalische Chemie, TU Darmstadt

Magnetic (Stern-Gerlach) and electric (Stark) beam deflection experiments in combination with density functional theory allow to study systematically the influence of the molecular structure on the magnetic response of pure and doped clusters. The dielectric properties of the ... more

Nano-polarity: an original manifestation of classical electrostatics
Prof. Claudine Noguera, Institut des Nanosciences de Paris, CNRS & Sorbonne Université, 4 place Jussieu, 75252 Paris cedex 05, France

Among all compound surfaces, polar surfaces are those which researchers have first tried to avoid as much as they could in the past, but which, eventually, have proved to be the richest in terms of structural and physico-chemical properties. Their stacking of charged atomic layer ... more

Pushing the limits of differential phase contrast microscopy - more than a mere facelift
Josef Zweck, Institut für Experimentelle und Angewandte Physik, Universität Regensburg

In contrast to its name, differential phase contrast (DPC) was initially interpreted as the deflection of a charged particle by a local field, in general a magnetic field within a specimen. Implicitly it was assumed that the field was constant over the extent of the electron prob ... more
