DESCRIPTION:Speaker: Philip Willke\nhosted by Johannes Fink\nAbstract: Scan
 ning tunneling microscopy (STM) has proven to be an excellent tool to acce
 ss and manipulate the nanoworld. Nevertheless\, up to now it did not allow
  for coherent manipulation of spin systems as it is common in other archit
 ectures. In this talk I will introduce how we establish a new framework fo
 r quantum coherent control and magnetic sensing of single atoms by combini
 ng electron spin resonance and STM. For instance\, this technique can be u
 sed to sense the magnetic coupling between atomic spin centers and also to
  detect the hyperfine interaction between their electron and nuclear spin.
  I will point out how we will extend this technique to a universal atomic-
 scale sensor to study magnetism in molecules and condensed matter systems 
 and how to improve the coherent properties of these atomic spin systems.In
  addition\, STM can be used to map the electron transport in a sample with
  ultimate spatial resolution. In this way\, it can reveal the electric res
 istance of localized defects such as grain boundaries. Here\, I will discu
 ss how we want to enhance this technique to access quantum transport pheno
 mena on the atomic scale and probe the influence of single adatoms and def
 ect centers.
