25.07.2017 – SPICE workshop Topology Matters starts

We welcome all the participants to theSPICE Topology Matters workshop. It brings  togetherthe top scientists in the fields of spintronics, superconductivity, topological insulators, and multiferroics in order to explore their connections via topology.

This will also be the first workshop of SPICE where the majority of the typical gender balance has been inverted!!

It promises to be an exciting workshop!

06.06.2017 – SPICE Spin Dynamics in the Dirac Systems workshop starts

We welcome the participants of the SPICE Spin Dynamics in the Dirac Systems workshop .

The workshop offer a platform for the knowledge exchange between diverse novel condensed matter domains such as topological insulators and superconductors, Weyl physics, topological Josephson junctions, spintronics in graphene, spin valves, spin-logic devices, quantum magnetism, spin lattices, frustrated magnets, spin liquids, non-trivial spin states, etc.

We wish you all a very productive meeting!

20.12.2016 – INSPIRE Group & Kläui Lab opened new Communication Zone

Yesterday, after three months of planning and construction, Jairo Sinova and Mathias Kläui opened the new Communication Zone. The shared communication space will be open for all members of the INSPIRE-Group, SPICE, the Kläui-Lab and their guests. The ComZone allows both groups to meet, discuss and work together on projects in a nice and modern working environment.

At the inauguration both group leaders were looking forward to even more interchange between the groups: "Whether you're just having a discussion over a cup of coffee, or a large scientific meeting, the new ComZone will be the perfect place for you. We like to thank the institute of physics for making this possible, as well as everybody who was involved in this project."

17.06.2016 – SPICE Young Research Leaders Group Workshop: New Paradigms in Dirac-Weyl Nanoelectronics

With the impending end of traditional Si based electronics due to Moore's law limitations, the need for novel approaches to next generation device design is not only apparent, but has become a popular interdisciplinary research topic. From research in fabrication engineering and device architectural design to devices based on intrinsically different physics, there is ample room for research from physics, chemistry, and engineering perspectives. From June 13th to 17th, the SPICE Young Research Leaders Workshop was held to approach the problem from a primarily materials perspective aiming to use external stimuli such as classical gating, ionic liquid gating, optical excitation, magnetic field control, strain, etc. to cause large physical property changes in Dirac and Weyl materials due to their unique, sensitive and modifyable Fermi surfaces. Together with co-organizer Jairo Sinova, the organizers Mazhar Ali and Binghai Yan brought together 22 young experts in theoretical and experimental physics, solid state chemistry, and electrical engineering in a multi-disciplinary collaborative effort to quickly bring the exciting new physics of Dirac and Weyl materials to practical application. Through the foundations laid in this workshop, we hope to spark a new field of electronics, discover new materials, new properties, new physics, and possibly create devices based on changing between fundamental states of matter.

20.05.2016 – SPICE Workshop: Quantum Acoustics – Surface Acoustic Waves meets Solid State Qubits

This week, SPICE hosted a Workshop boosting the new field of Quantum Acoustics‐ a phonon analogue of quantum optics on chip – where single phonons in the form of high‐frequency surface acoustic waves (SAWs) propagate in acoustic waveguides coupling remote qubits. The team of organisers consisted of Göran Johansson (Chalmers, Sweden), Christopher Bäuerle (CNRS, France), Paulo Santos (PDI, Germany) and Floris Zwanenburg (Twente, Netherlands). They brought together three scientific communities which have not interacted substantially before, i.e. Surface Acoustic Waves, Solid State Spin Qubits and Superconducting Qubits. In the beautiful location of Schloss Waldthausen, fifty-two international scientists used talks, discussions and a poster session to explore contact points and potential synergies for these three fields. We thank the organizers and all participants for a successful workshop.

23.10.2015 – “Spin Orbit Coupling and Spin Mechanics” Workshop

On October 23rd and 24th, SPICE hosted the 29th REIMEI and ERATO-SQR workshop. The organisers Junichi Ieda and Jairo Sinova brought together leading theorists and experimentalists to work on effects of the spin-orbit interaction and the coupling of the spin and lattice degrees of freedom in magnetic nanostructures.

Being an efficient spin current detector and generating so-called spin-orbit torques on proximity magnets, the spin Hall effect has moved into the mainstream of magnetism. 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 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.
