2025 ICTP Prize awarded to Titas Chanda, Sthitadhi Roy, Pg2

Key Highlights:

• The 2025 ICTP Prize has been awarded to Titas Chanda of IIT-Madras and Sthitadhi Roy of the International Centre for Theoretical Sciences, Bengaluru.
• The prize recognizes their contributions to the theory of quantum many-body systems, at the interface of condensed matter and quantum information science.
• Their work has opened new directions in understanding non-equilibrium dynamics of quantum systems, quantum correlations, and measurement-driven phase transitions.
• The ICTP Prize is awarded annually to young scientists from developing countries and includes a certificate and a cash component.
• The ICTP was founded in 1964 by Abdus Salam to support scientists from developing countries.

Detailed Insights:

• Titas Chanda's work includes contributions to quantum information science and quantum many-body physics, focusing on quantum correlations and open quantum systems, with applications in quantum batteries, communication protocols, and resource theories.
• Sthitadhi Roy's research focuses on the non-equilibrium dynamics of quantum many-body systems, including work on measurement-induced phenomena, many-body localisation, and emergent phases of quantum matter, with results on hybrid quantum circuits.
• Quantum many-body systems involve numerous interacting quantum particles, such as electrons in a solid or atoms in an ultracold gas, where their collective behavior is determined by their interactions.
• Condensed matter physics studies the collective behavior in materials, addressing questions about phases, magnetization, heat conduction, and phase transitions.
• Quantum information science treats quantum states as information, utilizing concepts like entanglement and entropy to characterize and manipulate them.
• The research is relevant to controlling quantum devices like quantum computers and sensors, and understanding their behavior when not in equilibrium.
• Past winners of the ICTP Prize from India include prominent scientists such as Mohit Kumar Jolly, Narendra Ojha, and Ashoke Sen.
