Worldsheet Correlators in Black Hole Microstates

Area of Science:

• Theoretical physics
• String theory
• Black hole physics

Background:

• Black hole microstates offer insights into quantum gravity.
• An exact string worldsheet description for certain microstates was recently discovered.

Purpose of the Study:

• To construct physical vertex operators for black hole microstates.
• To compute heavy-light correlators and match them with holographic duals.
• To develop a formula for correlators with multiple light insertions.

Main Methods:

• Construction of physical vertex operators.
• Computation of heavy-light correlators.
• Comparison with holographically dual conformal field theory.

Main Results:

• The first match between worldsheet correlators and holographic duals was achieved.
• A closed formula for correlators with arbitrary light insertions was conjectured.
• The analogue of the Hawking radiation rate for these microstates was computed.

Conclusions:

• The study establishes a concrete link between string theory and quantum field theory descriptions of black hole microstates.
• The findings pave the way for deeper investigations into black hole thermodynamics and quantum information.
• This work provides a new tool for studying black hole dynamics and Hawking radiation.
