Deepak Dhar Dirac Medal recognition marks a major achievement for Indian theoretical physics. Dhar, a leading statistical physicist, has been awarded the 2026 Dirac Medal for his contributions to theoretical physics, particularly statistical mechanics. One of his best-known contributions is the Abelian Sandpile Model, a mathematical framework for studying self-organised criticality. The model helps to explain how complex systems can naturally evolve towards a critical state through simple local interactions. Dhar’s research has also produced important theoretical results involving random lattices, fractals, directed percolation and related statistical-mechanics problems. India’s Shanti Swarup Bhatnagar Prize profile notes his contributions to the theoretical understanding of statistical mechanics and kinetics on random lattices. The Dirac Medal, awarded annually by the International Centre for Theoretical Physics, recognises significant contributions to theoretical physics. Dhar’s achievement highlights the global impact of Indian research in fundamental science.
