Overview
- Researchers Aninda Sinha and Faizan Bhat at IISc’s Centre for High Energy Physics report the finding in Physical Review Letters in December 2025.
- Ramanujan’s 1/π series emerge within logarithmic conformal field theories, a framework used to describe scale-invariant systems at criticality.
- The team demonstrated computational gains for selected quantities in these theories, with potential to inform work on percolation, turbulence and aspects of black hole descriptions.
- Ramanujan listed 17 highly efficient 1/π series in 1914, a legacy that underpins modern algorithms such as Chudnovsky used to compute roughly 200 trillion digits of π.
- The study was motivated by the question of why Ramanujan’s extraordinary formulas exist, seeking a physics-based origin for their structure.
