The International Centre for Theoretical Physics stated that the 2025 ICTP prize was awarded to Titas Chanda of IIT-Madras and Sthitadhi Roy of the International Centre for Theoretical Sciences. The duo is recognised for their contribution to the theory of quantum many-body systems, at the condensed matter and quantum information science interface.
According to the statement released by the body, the duo has made an exceptional contribution to the theory and their work added previously unknown dimensions to the understanding of neo-equilibrium dynamics of quantum systems. The physicists have studied quantum particle dynamics using concepts of condensed matter physics.
The concept helps in understanding the problems faced by quantum computers and sensors when they are not in equilibrium. ICTP, founded by Nobel Laureate Abdus Salam in 1964, aims to support scientists from developing countries. In conversation with The Hindu, Dr Chanda said that the organisation has nurtured and supported India’s physicist community for over a decade. Expressing his gratitude, he affirmed that it was profound to be recognised by an institution that has shaped so many scientists for over a decade.
The quantum many-body systems contain several smaller ‘quantum’ pieces. Such as electrons in a solid, or atoms in ultracold gas. In the system, their collective behaviour is dominated by their overall interactions. Since each particle interacts and affects the other, it was tough for physicists to understand the entire system by solving for one particle at a time.
Condensed matter is the branch of physical Sciences dealing with the behaviour of engineered Matter and materials, including superconductors and magnets. According to the organisation, Dr Chanda developed numerical tools and results across areas, including cold atoms and quantum optics. Dr Roy, who is an assistant professor at the International Centre for Theoretical Sciences in Bengaluru, shared the award for his contribution to the non-equilibrium dynamics of the quantum many-body systems.
The award, starting in 1982, includes a certificate and cash prize given annually for exceptional contributions to physics.
