Deepak Dhar Wins Dirac Medal: Indian Physicist Honoured by ICTP

Deepak Dhar Wins Dirac Medal as the Indian physicist receives one of the major international honours in theoretical physics. Professor Deepak Dhar has been awarded the 2026 Dirac Medal and Prize by the International Centre for Theoretical Physics (ICTP) for his important contributions to statistical mechanics.

The award has been jointly given to four scientists: Deepak Dhar of India, Bernard Derrida of France, Marc Mézard of Italy, and Haim Sompolinsky of Israel and the United States. Their research has helped expand the understanding of statistical mechanics and its connections with other scientific fields.

Who Is Deepak Dhar?

Professor Deepak Dhar is a prominent Indian theoretical physicist known for his work in statistical physics, stochastic processes and complex systems.

He spent many years at the Tata Institute of Fundamental Research (TIFR) in Mumbai. He later worked at IISER Pune and joined the International Centre for Theoretical Sciences (ICTS-TIFR) as an INSA Distinguished Professor.

His major research areas include:

Statistical physics.
Stochastic processes.
Self-organised criticality.
Complex systems.
Mathematical models of physical systems.

Why Did Deepak Dhar Receive the Dirac Medal?

A major part of Dhar’s research is related to the Abelian sandpile model, which is used to study complex systems and self-organised criticality.

The idea can be understood through a simple example. When grains of sand are added slowly to a pile, it may remain stable for some time. But after reaching a certain point, adding one more grain can trigger an avalanche.

Dhar established important mathematical properties of the Abelian sandpile model and developed an exact solution for it. His work became an important contribution to the study of self-organised criticality and statistical mechanics. (ictp.it)

What Is Statistical Mechanics?

Statistical mechanics is a branch of physics that uses mathematics and probability to understand the overall behaviour of systems containing a very large number of particles.

Instead of studying each particle individually, scientists look at patterns and behaviour at a larger scale.

Its ideas are now useful in areas such as:

Physics and mathematics.
Computer science.
Optimisation.
Neuroscience.
Artificial intelligence.

Other Awards Received by Deepak Dhar

The Deepak Dhar Wins Dirac Medal achievement adds another major honour to his scientific career.

He has previously received several important awards, including:

Shanti Swarup Bhatnagar Prize – 1991
ICTP Prize – 1993
TWAS Prize – 2002
Boltzmann Medal – 2022
Padma Bhushan – 2023

The Boltzmann Medal recognised his contribution to statistical physics, while the Padma Bhushan recognised his contribution to science and research.

Other 2026 Dirac Medal Recipients

The 2026 Dirac Medal was jointly awarded to:

Bernard Derrida – France.
Deepak Dhar – India.
Marc Mézard – Italy.
Haim Sompolinsky – Israel and USA.

Their research has contributed to statistical mechanics and influenced areas such as optimisation, theoretical neuroscience and artificial intelligence.

Why Is the Award Important?

Deepak Dhar Wins Dirac Medal is significant for India because it highlights the contribution of an Indian scientist to theoretical physics at the international level.

His research demonstrates how mathematical models can help scientists understand complex systems. The recognition also shows how statistical mechanics continues to influence different areas of modern science.

Conclusion

Deepak Dhar Wins Dirac Medal is an important milestone in his long scientific career. His research on the Abelian sandpile model, self-organised criticality and statistical physics has contributed to a better understanding of complex systems.

The honour adds another notable achievement to his career and brings further recognition to India’s contribution to theoretical physics.
