 tps://epfl.zoom.us/j/68507823417\nPasscode: 4154\n\nProf. Ingrid Mertig\nM
 artin Luther University Halle-Wittenberg (Germany)\n\nTransversal transpor
 t coefficients and topological properties\nSpintronics is an emerging fiel
 d in which both charge and spin degrees of freedom of electrons are utiliz
 ed for transport. Most of the spintronic effects—like giant and tunnel m
 agnetoresistance—are based on spin- polarized currents which show up in 
 magnetic materials\; these are already widely used in information technolo
 gy and in data storage devices.\nThe next generation of spintronic effects
  is based on spin currents which occur in metals as well as in insulators\
 , in particular in topologically nontrivial materials. Spin currents are a
  response to an external stimulus—for example electric field or temperat
 ure gradient—and they are always related to the spin-orbit interaction. 
 They offer the possibility for future low energy consumption electronics.\
 nThe talk will present a unified picture\, based on topological properties
 \, of a whole zoo of transversal transport coefficients: the trio of Hall\
 , Nernst\, and quantum Hall effects\, all in their conventional\, anomalou
 s\, and spin flavour. The formation of transversal charge and spin current
 s and their interconversion as response to longitudinal gradients is discu
 ssed.\n\nAbout the speaker\nIngrid Mertig is a professor at the institute 
 of physics of Martin Luther University Halle-Wittenberg\, Germany.\nShe re
 ceived her doctoral degree from the Technische Universität Dresden in 19
 82. She was a postdoctoral researcher and senior scientist at the Joint In
 stitute for Nuclear Research (Russia)\, and was a regular guest scientist 
 and guest professor at several universities.\nShe has been a professor at 
 Martin Luther University since 2001 and her main research interests includ
 e the quantum theory of solids\, density functional theory\, transport the
 ory\, theory of magnetism\, physics of nanostructures\, spintronics and to
 pological properties of solids.\n\n\nDid you miss previous MARVEL Disting
