Key takeaways

Prof. Deepak Dhar became the second Indian scientist to win the prestigious 2026 Dirac Medal in theoretical physics.
He shared the award with physicists Bernard Derrida, Marc Mézard, and Haim Sompolinsky for breakthroughs in statistical mechanics.
Established in 1985 by the International Centre for Theoretical Physics (ICTP) in Trieste, Italy, the medal excludes current Nobel Prize winners by rule.
Prof. Dhar previously received the Padma Bhushan (2023) and the Boltzmann Medal (2022) for his landmark work on the Abelian Sandpile Model.

Renowned Indian physicist Prof. Deepak Dhar has been awarded the 2026 Dirac Medal by the International Centre for Theoretical Physics (ICTP).
He shared this international award with physicists Bernard Derrida, Marc Mézard, and Haim Sompolinsky for outstanding research in statistical mechanics.

The ICTP Dirac Medal ranks among the highest global honours in theoretical physics and bears the name of British physicist Paul A. M. Dirac.
The institution formally instituted this international recognition in 1985.
The International Centre for Theoretical Physics (ICTP) in Trieste, Italy, confers this medal, an institute founded in 1964 by Nobel laureate Abdus Salam.
The award aims to honor transformative achievements while supporting exceptional scientists who have not yet won the Nobel Prize, Fields Medal, or Wolf Prize.

Award rules strictly prohibit active Nobel Laureates, Fields Medallists, or Wolf Prize winners from receiving it, though several recipients later earned the Nobel Prize.
It specifically honors mathematical and conceptual breakthroughs in quantum mechanics, string theory, particle physics, and statistical mechanics.
The medal promotes scientific talent globally, upholding founder Abdus Salam's vision of encouraging research in developing countries.
Prof. Deepak Dhar is the second Indian scientist to earn this honor, following string theorist Ashoke Sen in 2012.

He established the mathematical framework for the Abelian Sandpile Model, revealing how simple physical interactions lead to self-organized critical states.
He proved the Abelian property, demonstrating that cascading collapses in a sandpile always reach an exact and predictable end state regardless of sequence.
Researchers apply his mathematical models to explain complex natural and social events, such as earthquakes, forest fires, neural networks, traffic jams, and stock market shifts.
Having received the Padma Bhushan (2023) and Boltzmann Medal (2022), Dhar built India's research environment over 40 years across TIFR, IISER Pune, and ICTS Bengaluru.
