Title: Upgrading Electronics with Spins and Topology

Abstract: 

After decades of systematic miniaturization of electronic devices the speed and efficiency provided by conventional electronics are reaching their limits. Those limitations are intrinsically related to the operational principles of electronic devices based on charge manipulation. As an alternative to conventional electronics, Spintronics (or spin electronics) offers great potential for faster, more powerful and yet more efficient devices. Spintronic devices use the intrinsic magnetic moment (spin) of electrons, which is ignored in conventional electronics, for building operational functionalities such as nonvolatile information storage, sensing, and logics. Furthermore, under certain conditions, a strong interaction between the spins and momenta of the carriers can lead to the emergence of topological phases of matter and the physical realization of new topological materials and quasiparticles such as Majorana fermions and parafermions. These exotic quasiparticles obey non-Abelian statistics and are therefore very promising for the implementation of fault-tolerant quantum computing.

This talk will provide an overview of the active research field of Spintronics, from its quantum mechanical principles to device concepts, and daily life applications. The possibility of exploiting topological protection for tackling undesired obstacles such as dissipation, heating, and quantum errors will also be discussed
