Cosmic Censorship in a Dual Collider

Area of Science:

• Theoretical Physics
• String Theory
• Holography

Background:

• Investigating cosmic censorship in anti-de Sitter (AdS) space is crucial for understanding quantum gravity.
• Holographic models provide a framework to study quantum field theories via gravitational duals.
• Previous work often focused on simpler boundary conditions or specific theories.

Purpose of the Study:

• To examine cosmic censorship in holographic models of anti-de Sitter space with good singularities.
• To analyze the behavior of black-brane spacetimes and their boundary fluid dynamics.
• To understand the role of quantum effects and phase transitions in resolving singularities.

Main Methods:

• Utilizing supersymmetric truncations of string/M theory.
• Constructing black-brane solutions with receding horizons in anti-de Sitter space.
• Analyzing curvature invariants and boundary hydrodynamic evolution.

Main Results:

• Solutions describe a boost-invariant fluid at the boundary with monotonically decreasing temperature.
• Classical gravity predicts unbounded curvature invariants at the horizon.
• Quantum effects or phase transitions can lead to regular geometries or allow continued hydrodynamic evolution.

Conclusions:

• Cosmic censorship in these holographic models depends on quantum corrections or phase transitions.
• Finite-N or finite-coupling effects are essential for a complete description.
• The interplay between gravity and boundary field theory is key to understanding singularity resolution.
