Workshop on Spin Transport and Spin Pumping in Organics

September 14th-15th 2015

This workshop focused on understanding and manipulating spin and charge transport through pi-conjugated polymers and exploiting its many possibilities. It explored the synergies that bringing closer together the spintronics and organics community can yield. The workshop is closely linked to the focus of the recent ERC Synergy grant "Spin-charge conversion and spin caloritronics at hybrid organic-inorganic interfaces".

Workshop on Magnetic Adatoms as Building Blocks for Quantum Magnetism August 2015

August 17th-20th 2015

The communities of quantum magnetism and surface nanomagnetism have been, so far, two different worlds, without many common interests and problems.  Recent developments in scanning tunneling microscopy (STM) now permit probing and fabricating spin chains and many other artificial spin systems, providing a new ground to explore quantum magnetism phenomena.  The potential  synergy that this approach can bring forward has been illustrated by the recent observation of Majorana quasiparticles on nanoengineered  spin chains by means of STM spectroscopy.

1) The quantum magnetism community learned about the exciting new possibilities to explore quantum magnetism in nano engineered spin chains.

2) The surface magnetism community learned about the fascinating physical concepts  that are being explored in quantum magnetism.

Problems of interest included fabrication and probing nanoengineered spin systems, quantum spin liquid properties in finite size systems, the emergence of non-trivial phenomena such as fractionalization in finite size systems, the interplay between Heisenberg coupling between magnetic atoms on a surface and their Kondo coupling, the interplay between magnetism and superconductivity in interacting spin chains, including the emergence of Majorana particles, the transition between quantum and classical behavior in spin systems.

FORMAT: The meeting lasted 4 days and brought together 50 researchers. The program included three types of talks:

1. School-like invited lectures, 50+10 minute discussion,  tutorial style covering well established results, trying to reach the non-experts.
2. Workshop-like 25+5m invited talks, presenting results that are potentially appealing for the two communities.
3. Contributed talks (15+5m) with recent developments in these rapidly evolving fields.

There was a total of 7 tutorials, distributed over the program and followed by focused shorter talks.  In addition, poster sessions were held intercalated in the middle of the program, and formed an important part of the program. Plenty of time was allocated for additional discussions.

Young Research Leaders Group Workshop:
Frontiers with strongly correlated and topological mesoscopic systems

August 3rd-14th 2015

This workshop, which was the first of its kind, aimed to start new and increasing collaborations, and seek for research topics of tomorrow across disciplines in condensed matter physics. The workshop format focused on groups of researches at their early careers but with already established and highly regarded research profiles. It brought together the research excellence elite of the next generation.

The format of the meeting during the first week included detailed introductory talks followed by more technical presentations. The second week of the meeting provided time for participants to fruitfully interact, exchange ideas and make study groups to learn from each other.

The main theme of this first workshop was to explore frontiers with strongly correlated and topological mesoscopic systems. The specific topics included:

• nonlinear, helical, spiral Luttinger liquids and quantum Hall edge states;
• superconductor/topological insulator (or quantum Hall) nanostructures
• many-body localization
• 2D physics at oxide interfaces
• 3D quantum materials: Dirac, Weyl , Kondo, 3He, Spin liquids, etc

SPICE-Workshop on Bad Metal Behavior in Mott Systems

June 29-July 2 (2015), at Schloss Waldthausen, Mainz

Introduction

The "Bad-metal" behavior phenomenon is often viewed as one of the key unresolved signatures of strong correlation physics. It has been identified in many Mott systems, such as cuprates, manganites, ruthenates, iridates, heavy fermions, organic charge-transfer salts, and the recently discovered iron pnictides. Many of the exotic features of these materials have been linked to quantum criticality of the Mott metal-insulator transition type. Many open fundamental questions still beg a convincing answer and may require to re-examine the familiar paradigms and to venture beyond it in new directions. It is an area that merges many different theoretical branches ranging from spin-fluctuation theories, to dynamical mean-field theory methods, to topological field theories, and even holographic duality - ideas borrowed from superstring theory. These fundamental emergent physics topics are now being applied in the design and fabrication of new devices for future technology. “Memristive” resistance-switching devices, novel power transistors, as well as “synaptic” devices that mimic the function of the neuron, are just a few of the possibilities.

This workshop addressed both the fundamental issues associated with this new type of phase transition, and its many consequences for material science and technology. Our invited speakers covered the most exciting discoveries in this broad field. The workshop immersed scientific talks, overview talks aimed to the other communities, and round table discussions of future directions. This aspect was of particular value to graduate students, postdocs, and early-career faculty members.

Besides the talks, there were several hour-long lectures of educational/review character. In addition, the participants contributed poster presentations.

SPICE-Workshop on Computational Quantum Magnetism May 2015

May 22nd - 25th 2015

In the last decade substantial progress has been made in computational magnetism. The leading ab initio codes have acquired capability to handle noncollinear spin systems, including spin spirals, which allows for comprehensive studies of most important magnetic systems, such as rare earth and 5d-based materials, dilute magnetic semiconductors, spin-polarized surface and interfaces etc. Advances beyond the density functional theory, such as the dynamic mean field theory (DMFT) or ab initio Gutzwiller methods allows proper handling of strongly correlated systems.

   At the same time development of model approaches such as functional renormalization group, direct diagonalization or Monte Carlo simulations have also been developed considerably and their capability has expanded far beyond the level of a decade or two ago.

    This workshop brought  together model and computation theorists, as well as some experimentalists, to summarize the progress that has been made in the last 10-15 years, formulate outstanding problems and promote cooperation between different directions.
