Tailoring Nano-Scale Systems by a Bottom-Up Design Atom-by-Atom

IAS@NTU STEM Graduate Colloquium webinar by Professor Roland Wiesendanger (University of Hamburg, Germany).
Prof Wiesendanger's scientific interests are in nanoscience and nanotechnology. He has received numerous prizes and awards, and is the first scientist in Europe to receive the Advanced Grant of the European Research Council three times.
The ability to construct nanoscale systems with atom­ic-level precision by using scanning tunneling microscope (STM)-based single-atom manipulation techniques has led to numerous outstanding examples of quantum designer phys­ics.
Investigating such artificially built spin arrays on superconductor surfaces has recently led to the observation of Majorana quasi particles which offer great potential applications for topological quantum computation.
Prof Wiesendanger will also demonstrate that the spatio-temporal control of atomic­ scale spin systems interacting with superconducting substrates forms the basis for interesting novel types of quantum materials and devices.
