      abstract = {This book highlights the doctoral research of the author  on electronic band structure engineering and ultrafast  dynamics of Dirac semimetals. Dirac semimetals exhibit  unique electronic band structure and novel physical  properties with rich light-matter interaction, which  inspires a wide range of potential applications. Enabling  band engineering and revealing ultrafast dynamics of Dirac  semimetals is therefore important. In the research work  covered by the book, the first ultrafast time- and  angle-resolved photoemission spectroscopy with tunable  probe photon energy is developed, providing new  opportunities for exploring ultrafast dynamics in 3D  quantum materials. Using the spectroscopy, the author  investigates the band structure engineering and ultrafast  dynamics of Dirac semimetals, realizing the  long-sought-after chiral symmetry breaking in a  Kekul-ordered graphene with flat band and revealing the  ultrafast dynamics of Dirac fermions in 3D Dirac semimetal  for the first time. The work advances the research of the  electronic structure of Dirac semimetals in two aspects.  Firstly, it identifies the Kekul-ordered graphene as a new  system for exploring chiral symmetry breaking- related  physics and flat band- induced instability, providing a  very rare system to investigate their interplay. Secondly,  it solves the long-standing challenge of directly  visualizing the non-equilibrium electronic structure of 3D  Dirac semimetal and opens up new opportunities for  exploring the light-matter interaction in 3D quantum  materials, especially the light-induced topological phase  transitions in 3D topological materials.},
