We welcome today's guest, Andre Thiaville, from Laboratorie de Physique des Solides ORSAY. He will be discussing Skyrmion in symmetric bilayers. Please join us to hear about the newest development in this hot topic.
We congratulate Olena (Helen) Gomonay on obtaining her first DFG research grant “SHARP: Spintronics witHAntiferRomagntes and Phonos”. Well done Helen!
The proposed research project will open and explore new ways to detect and manipulate antiferromagnets using phonons and magneto-elastic coupling effects.
Prof. Jairo Sinova and Bertrand Dupé are visiting the group of Prof. Paul Kelly at the University of Twente for a couple of days. It is a pleasure to visit the group of Prof. Kelly and benefit from his long experience in spin transport calculations from ab initio.
We congratulate Dr. Karin Everschor-Sitte, group leader of TWIST, for receiving the Hertha-Sponer-Preis 2018
We welcome Eric Bousquet from the Abinit team who will be giving the seminar today. We look forward to future collaborations with his team.
We welcome today Dr. Oliver Breunig from the Institute of Physics II at the University of Cologne, hosted by TWIST. He will give a talk on “Gigantic Negative Magnetoresistance in a Disordered Topological Insulator”.
Details: “Recently the phenomenon of negative magnetoresistance (MR) is attracting renewed interest due to its occurrence in Weyl semimetals because of the chiral anomaly. In other systems a large MR typically relates to magnetism. In this talk a novel mechanism leading to a large negative MR will be presented that is based not on magnetism, but on disorder. In the newly synthesized bulkinsulating topological insulator material T1BixSb1-xTe2 we find a suppression of the resistivity by up to 98 % in 14 T at low temperature. From transport data and numerical simulations, this gigantic negative MR is understood by a percolation of charge puddles formed in the disordered bulk.”
The TWIST and INSPIRE guest Davi R. Rodrigues from the Department of Physics & Astronomy, Texas A&M University gives a talk on “Effective Description of Topological Magnetic Textures”.
We welcome today's seminar speaker, Roman Kovakick, from Jülich, who will be discussing Spin disorder and transport in magnetic materials from an abi-initio perspective.

Today starts the SPICE workshop Exotic New States in Superconducting Devices: the Age of the Interface .
We welcome all the participants and hope they have a fruitful workshop!
