Holographic Subregion Complexity and Fidelity Susceptibility in Noncommutative Yang--Mills Theory

ui.adsabs.harvard.edu

Cutting-edge physics asks whether the fabric of spacetime itself is quantized — and holographic complexity in noncommutative Yang-Mills theory may be the thermometer that tells us.

Theory Briefing

  • Holographic subregion complexity measures how hard it is to reconstruct a chunk of spacetime from quantum information — and noncommutativity changes that cost.
  • In noncommutative Yang-Mills theory, space coordinates don't commute, meaning geometry at small scales is fundamentally fuzzy and classical intuitions break down.
  • Fidelity susceptibility tracks how sensitive a quantum state is to tiny perturbations, offering a probe of phase transitions invisible to standard thermodynamic tools.
