Abstract: Weyl and Dirac semimetals are novel topological quantum materials with interesting phenomena and exotic effects rarely found in solids. Because of their unusual relativistic-like linear energy spectrum and the nontrivial topology of the band structure, Weyl and Dirac materials attracted significant theoretical and experimental attention. In this colloquium, I will focus on the key electronic properties and discuss what makes these topological materials interesting. I will overview a part of my past and ongoing research program by highlighting several effects connected with the electron hydrodynamics, strain-induced effective axial gauge fields, and the manifestations of the electron state topology in collective modes and transport.
