DESCRIPTION:Recent developments in thin film growth techniques and in ab i
 nitio calculation capabilities have enabled the synthesis of atomically fl
 at surfaces and heterostructures\, and the prediction of their electronic 
 properties.  A common thread across several such thin film materials and h
 eterostructures – heavy metal compounds and multilayers – is that the 
 spin orbit coupling strength at surfaces and interfaces is comparable to t
 he other relevant energy scales\, and thus plays a pivotal role.  Novel sp
 in-based phenomena emerge often robust to disorder and thermal fluctuation
 s\, with much promise for room temperature applications.  Notable progress
  has been made on spin-polarized states at Rashba interfaces\, topological
  insulator surfaces and atomically thin materials.  This includes their ut
 ility towards generation and conversion of spin currents\, the development
 s on interfacial non-collinear spin textures in magnetic films\, and techn
 iques to generate\, stabilize and manipulate them in devices.  Using magne
 tic nanoscale spin structures as a paradigm\, I will elaborate on the inte
 llectual and practical developments towards the technology of spin and cha
 rge topology of the future.
