If you have a question about this talk, please contact Dr Hannah Price. In the lecture an attempt to survey the physics of electronic topological transitions from the very first paper until the recent achievements is made. The presentation is started from the description of the possible topological singularities in electronic spectra of metals. Then the singularities of thermodynamic and transport properties of a metal in the vicinity of ETT will be discussed. The transport phenomena including behavior of conductivity and thermoelectric coefficient in the vicinity ETT are discussed. The second part of the lecture will be devoted to the discussion of the modern problems of ETT physics, applications of it to the study of 2D systems, graphene, heavy fermion compounds and gapless superconductors. This talk is part of the Theoretical Physics Seminars series. ## This talk is included in these lists:- Bham Talks
