Tachyon condensation and black hole entropy

Area of Science:

• String theory
• Black hole thermodynamics
• Quantum gravity

Background:

• Black hole entropy is a fundamental concept in quantum gravity.
• String theory offers a framework to understand microscopic origins of black hole entropy.

Purpose of the Study:

• To compute the entropy of large mass black holes using string propagation on a cone with a specific deficit angle.
• To verify theoretical predictions by comparing computed entropy with established Bekenstein-Hawking entropy.

Main Methods:

• Analyzing string propagation on a cone geometry with a deficit angle of 2π(1-1/N).
• Utilizing recent results on the condensation of twisted-sector tachyons within this string theory framework.

Main Results:

• The entropy calculated through string condensation precisely matches the Bekenstein-Hawking entropy.
• The study demonstrates agreement between string theory computations and black hole thermodynamics.

Conclusions:

• String theory provides a consistent explanation for black hole entropy.
• The condensation of twisted-sector tachyons is a key mechanism for determining black hole entropy in this model.
