Transport Experiments for Weyl Semimetals

Explore transport experiments for Weyl semimetals in this 77-minute seminar presented by Prof. Eduard V. Devyatov from the Institute of Solid State Physics RAS. Delve into the fascinating world of Weyl semimetals, a novel class of topological systems where chiral (directed) surface states coexist with gapless bulk spectrum. Learn about the fundamental challenge of isolating the contribution of these states and discover physical effects where topologically protected surface states play a crucial role. Examine experimental results from heterostructures based on Weyl semimetals and materials with macroscopic order parameters (superconductor, ferromagnet), highlighting both the topological protection of these states and the spin-momentum locking phenomenon.
