Breakthrough Study Links Hawking Radiation to Black Hole Complexity

10/25/2025

Summary

Story summary

Tata Institute of Fundamental Research researchers, including Ritam Basu and Onkar Parrikar, study Hawking radiation complexity from evaporating black holes using Wigner negativity as a measure.
They find Wigner negativity stays constant before the Page transition but rises exponentially afterward.
They derive a universal Wigner negativity formula applicable across models, linking complexity to the entanglement wedge size.
The work advances quantum gravity insights and addresses the black hole information paradox.

History

Historical Context

In 1974, Stephen Hawking proposed that black holes emit radiation, now known as Hawking radiation, challenging the notion that nothing escapes them. This groundbreaking theory suggested that black holes could lose mass and eventually evaporate, leading to significant implications for quantum gravity. Recent research by Tata Institute scientists continues to explore the complexities of Hawking radiation and its connection to the black hole information paradox, a key issue in theoretical physics.
