Exotic New States in Superconducting Devices:
The Age of the Interface

Mainz, Germany: September 25th – 28th 2017




Superconducting material such as a ferromagnet, a topological insulator or a semiconductor, a range of electronic states can be induced which are radically different from either constituent material. To be able to probe these states requires a broad range of expertise, spanning basic materials science to fundamental physics modeling of interfaces and transport behaviour. At this meeting we have the opportunity to bring together scientists working on distinct and overlapping areas, such as superconductivity, magnetism, topological materials, quantum computing, and spin-electronics. This science community will have an opportunity to appreciate how these different transport phenomena are linked conceptually and thereby stimulate further understanding particularly with respect to realising useful devices with unique properties for spin-electronics and quantum computing.

26.09.2016 – Workshop on Antiferromagnetic Spintronics

Antiferromagnetic Spintronics

The emerging field of antiferromagnetic spintronics focuses on making antiferromagnets active elements of spintronic devices. From an application point of view, it emphasizes how to read, manipulate, and store information in these systems robustly. From the basic science point of view, it exploits the larger range of spin physics in this material due to the higher complexity of the ordered phase and order parameters.

New connections with the current ferromagnetic spintronics research have created entirely new ways of rethinking spin phenomena in antiferromagnets, while still building on long standing pioneering works in antiferromagnetic materials.

Although some prevailing concepts map directly between these fields, in many important instances the intuition built in the ferromagnetic spintronics systems can lead us astray in the antiferromagnetic systems.

The recent successes in this new area and rapid theoretical developments make this the right time for a conference on the subject.

21.09.2016 – Quantum Spintronics: Spin Transport Through Quantum Magnetic Materials

Quantum Spintronics

The field of magnon spintronics and the field of quantum magnetism have seen tremendous progress in recent years with many break-throughs in new concepts, new techniques, and new materials. Magnon spintronics has demonstrated electrical and thermal control over spin currents through magnetic insulators in contact with normal metals. Almost all this progress has been limited to a single material magnetic insultator YIG, hence limiting the outlook of the field. In Quantum Magnetism 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, as well as a much larger spectrum of quantum magnetic materials to explore.

Non-equilibrium Quantum Matter

Mainz, Germany: May 30th - June 2nd 2017

In contrast to equilibrium quantum systems, which exist in just a tiny corner of an immense configuration space, non-equilibrium quantum many-body systems can access the totality of configuration space and represent a rich resource for novel quantum states, including light-induced quantum-coherent phases of matter, topological phases and spin textures in solids and cold atom systems. Non-equilibrium many-body quantum dynamics is perhaps the last frontier in physics, where even the basic understanding is still lacking and a number of outstanding fundamental questions are wide open. However, there has been much recent progress in exploring these fundamental aspects on both theoretical and experimental sides.

This interdisciplinary workshop brings together leading experts – both theorists and experimentalists – working in the broad field and focuses on the most exciting recent developments in non-equilibrium many-body physics including: light-induced superconductivity, topological Floquet states, soliton motion in quantum superfluids, acoustic Hawking radiation in Bose-Einstein condensates, and quantum chaos and quantum butterfly effect.

The aforementioned developments, being the main motivation for the proposed workshop, make it clear that the theme of non-equilibrium quantum physics is not specific to a particular subfield, but cuts across different seemingly unrelated disciplines, including topological insulators, superconductors, cold atoms, bosonic and fermionic, neutral superfluids, driven cold atoms systems. The theory involved is equally diverse and spans fields from classical condensed matter, to mathematical physics (integrable systems and inverse scattering methods in the context of solitons), to even general relativity (geometric descriptions of superfluid’s dynamics).

The proposed program will include representatives from all these fields and promises to lead to a lively, intellectually stimulating, and highly interdisciplinary program. There will be a poster session on one of the days, where non-speakers can present their work, too.

Entanglement in Strongly Correlated Systems

Benasque, Spain: February 5th – 18th 2017

The study of entanglement in strongly correlated systems has lived a series of important advances in recent years, in turn underpinning a better understanding of the quantum properties of matter. Concerning numerics, examples of these are e.g. new numerical methods based on tensor networks (MPS, PEPS, MERA), as well as advances in quantum Monte Carlo, exact diagonalizations, and continuous unitary transformations. From an analytical perspective there are also recent relevant developments regarding e.g. AdS/CFT methods, entanglement spectrum, string-net models, and the tensor network description of chiral topological phases.

The aim of this 2-week meeting is to bring together specialists in the field as well as newcomers at the interface of quantum information and condensed matter theory. The format of the event will alternate introductory lectures with specialized talks. During these days, spontaneous informal discussions will be encouraged by the organizers and announced throughout the day. Our plan is to have a very rich and collaborative meeting.

Quantum Spintronics: Spin Transport Through Quantum Magnetic Materials

September 21st - 23rd 2016

The field of magnon spintronics and the field of quantum magnetism have seen tremendous progress in recent years with many break-throughs in new concepts, new techniques, and new materials. Magnon spintronics has demonstrated electrical and thermal control over spin currents through magnetic insulators in contact with normal metals. Almost all this progress has been limited to a single material magnetic insultator YIG, hence limiting the outlook of the field. In Quantum Magnetism 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, as well as a much larger spectrum of quantum magnetic materials to explore.

This workshop brings together these two communities, magnon spintronics and quantum magnetism, to explore new directions that exploit each others strengths. The goals of the workshop are:

1. For the quantum magnetism community to get up to speed on the recent developments in electrical control and detection of spin currents through magnetic insulators.
2. For the spintronics community to learn about new quantum magnetic materials that may host phases with exotic spin transport properties, such as spin superfluids and Bose glasses.
Topics include the spin Seebeck effect, spin pumping in ferromagnet/normal metal heterostructures, magnon Bose-Einstein condensation and spin superfluidity, spin and heat transport through magnetic insulators.

Workshop on "Spin Orbit Coupling and Spin Mechanics"


October 23rd - October 24th 2015 at the SPICE Center

The 29th REIMEI and ERATO-SQR workshop focused on effects of the spin-orbit interaction and the coupling of the spin and lattice degrees of freedom in magnetic nanostructures.

The spin Hall effect has moved into the mainstream of magnetism by generating so-called spin-orbit torques on proximity magnets and being an efficient spin current detector. The electrical and thermal actuation of the magnetization of insulators with extremely high quality factors of the magnetization dynamics has focused attention on the bosonic degrees of freedom in spintronics and the importance of the spin-lattice and spin-rotation couplings.

The scope of the workshop covered the following topics:

  • The magnon-phonon interaction in a magnetic insulator (YIG) to better understand acoustically induced spin pumping and the spin Seebeck effect.
  • Materials with large spin-orbit interaction examined by combining density functional theory in the local density approximation with the quantum Monte Carlo technique.
  • The effects of spin-orbit interaction on the magnetization dynamics of ferro-, feri-, and antiferro-magnets and their heterostructures.
  • Spin current generation in solids and fluids.
