Holographic Complexity And Cosmological Singularities

TL;DR

This paper investigates how holographic complexity evolves in models with cosmological crunch singularities, revealing that complexity decreases as the singularity nears, indicating simpler entanglement structures at the singularity.

Contribution

It introduces a study of holographic complexity in AdS/CFT models with cosmological singularities, showing complexity decreases near the crunch.

Findings

Complexity measured by extremal bulk volumes decreases approaching the singularity.

Quantum states exhibit simpler entanglement structures at the singularity.

Complexity evolution provides insights into the nature of cosmological crunches.

Abstract

We study the evolution of holographic complexity in various AdS/CFT models containing cosmological crunch singularities. We find that a notion of complexity measured by extremal bulk volumes tends to decrease as the singularity is approached in CFT time, suggesting that the corresponding quantum states have simpler entanglement structure at the singularity.
