Negative entropy in scrambling black holes
Koji Azuma
We present a microscopic statistical-mechanical foundation for interpreting the horizon area of a scrambling black hole as coherent information, equivalently negative conditional q…

Second law of black hole thermodynamics
Koji Azuma, Go Kato
If simple entropy in the Bekenstein-Hawking area law for a Schwarzschild black hole is replaced with 'negative' quantum conditional entropy, which quantifies quantum entanglement,…

Do black holes store negative entropy?
Koji Azuma, Sathyawageeswar Subramanian, Go Kato
The Bekenstein-Hawking equation states that black holes should have entropy proportional to their areas to make black hole physics compatible with the second law of thermodynamics.…
