Leading scientists on topological insulators met in Berlin
Outstanding researchers took part in the “New Trends in Topological Insulators 2014” - workshop.
From July 7-10, 150 researchers met in Berlin to discuss recent findings in the field of topological insulators.
Topological insulators are a rather new form of quantum matter with an insulating bulk and a metallic surface created by topologically protected and spin polarized electronic states.
Outstanding researchers took part in the “New Trends in Topological Insulators 2014” - workshop, organized by Gustav Bihlmayer (Forschungszentrum Jülich) and Saskia Fischer (Humboldt University and Oliver Rader of HZB. 20 speakers had been invited for presentations, the 2012 Buckley Prize winners Shoucheng Zhang and Laurens W. Molenkamp (also Leibniz Prize 2014), Zhi-Xun Shen (Buckley prize 2011) and Yoichi Ando (2014 Inoue Prize for Science) being among them.
Breakthrough results were delivered on topics such as optical excitation, electron-photon entangled states, the role of electron correlation as well as imaging of helical edge states and Majorana fermions.
The event took place on the premises of the Berlin-Brandenburg Academy of Sciences. It has been generously supported by DFG as well as HZB.
- Two winning entries from the HZB in the Helmholtz Imaging ContestA time resolved X-ray tomography by Paul H. Kamm, HZB, has won the second Jury prize and is the winner of the Helmholtz Imaging conference Partizipants Choice Award in this year’s competition. It shows a 3D snapshot of a laser welding process. Among the 20 most beautiful images is also a microscopy image of a solar cell by Yannic Kerkhoff and Daniel Abou Ras, HZB.
- Israel Ibukun Olaniyan receives the Helmholtz Doctoral Prize 2026At Helmholtz, more than 8,000 doctoral candidates conduct research. Eleven of them have now been honored for their original and outstanding work, among them Dr Israel Ibukun Olaniyan from the HZB. His doctoral thesis "Ferroelectricity at the nanoscale in epitaxial BaTiO3 on silicon" in the group of Professor Catherine Dubourdieu represents a step towards a new nanoelectronics based on topological defects, that can potentially help to create an energy efficient information technology.
- Only at BESSY II worldwide: IR nanoscopy at very long THz wavelengthsThe team at the IRIS beamline at BESSY II has created a new experimental option: They achieved infrared nanoscopy with a spatial resolution of around 50 nm at very long THz wavelengths. This was possible thanks to a temporal pattern of light pulses known as the low-alpha operating mode at BESSY II. Worldwide, BESSY II is the only synchrotron light source at which users could perform nanoscopy in a single setup from 25 to 4000 cm-1, a unique opportunity for ultra-broadband characterisation of complex materials at the nanoscale in both the life sciences and materials sciences.
