Physicist Deepak Dhar Wins 2026 Dirac Medal, Pg8

Key Highlights:

• Indian theoretical physicist Deepak Dhar has been named a co-recipient of the 2026 Dirac Medal, one of the highest honors in the field of theoretical physics.
• The award is presented by the Abdus Salam International Centre for Theoretical Physics (ICTP) in Italy.
• Dhar shares the medal with three other scientists: Bernard Derrida, Marc Mezard, and Haim Sompolinsky.
• In 2022, he became the first Indian to receive the Boltzmann Medal, another prestigious award in physics.
• His research focuses on statistical mechanics and complex systems, notably his work on the sandpile model.

Detailed Insights:

• The Dirac Medal was established in 1985 and is named after Paul Dirac, a Nobel laureate and a foundational figure in quantum theory.
• Dhar's work has been instrumental in explaining how simple interactions can lead to complex and unpredictable behaviors in large systems.
• His research has practical applications in modeling diverse phenomena such as earthquakes, traffic jams, and fluctuations in financial markets.
• He currently serves as an Indian National Science Academy (INSA) distinguished professor at the International Centre for Theoretical Sciences (ICTS) in Bengaluru.
• Prior to this, he held positions at the Tata Institute of Fundamental Research (TIFR), Mumbai, and the Indian Institute of Science Education and Research (IISER), Pune.
• The Boltzmann Medal is awarded triennially by the International Union of Pure and Applied Physics (IUPAP) for outstanding achievements in statistical mechanics.
• Dhar's contributions extend to equilibrium and non-equilibrium statistical mechanics, optimization problems, theoretical neuroscience, and artificial intelligence.
• He was also honored with the Padma Bhushan in 2023, one of India's highest civilian awards.

Scientific/Technical Concepts Involved:

• Theoretical Physics: A branch of physics that uses mathematical models and abstractions to rationalize, explain, and predict natural phenomena.
• Statistical Mechanics: A branch of physics that applies probability theory to study the average behavior of mechanical systems with many particles.
• Complex Systems: Systems composed of many interacting parts whose collective behavior is often non-linear and difficult to predict from individual components.
• Sandpile Model: A mathematical model used to illustrate self-organized criticality, where small, local changes can lead to large, system-wide events.
