Prabhat Mandal obtained his Ph.D (1993) at the Saha Institute of Nuclear Physics on high-temperature superconductivity. Then he was a post-doctoral fellow at Grenoble high magnetic field laboratory, France, with the French Govt. C.I.E.S. Fellowship and UNESCO Fellowship and at Max Planck Institute, Grenoble, and University of Goettingen, Germany, with Alexander von Humboldt Fellowship. He joined the Saha Institute of Nuclear Physics as a faculty in the year 1996. At present, he is an Emeritus Professor at S. N. Bose National Centre. He received a research award from the Third World Academy of Sciences, Italy, and SINP Foundation Day award for high-quality publications. He is a fellow of the Indian Academy of Sciences & Indian National Science Academy. His field of research includes strongly correlated electrons, superconductivity, colossal magnetoresistance, topological insulator, Dirac/Weyl semimetals, charge density waves, magnetic and non-magnetic van der Waals systems, etc. He was elected fellow of the Indian Academy of Sciences in 2019.

A new paradigm for understanding solids
The discovery of Dirac- and Weyl-type excitations in electronic systems is a major breakthrough in recent condensed matter physics. These non-trivial topological electronic states are protected by different types of symmetries and are important for fundamental research and technological applications. At first, we briefly discuss the conventional electronic states, which have been realized in the band theory of solid. Then the theoretical foundation and experimental realization of topological electronic states in several condensed matter systems will be discussed.
