Quantum methods/correlation.

Overview

They are central objects in statistical mechanics and quantum field theory and determine observable quantities such as spectra and response functions.

Types

  • Two-point correlation functions
  • Higher-order correlations

Applications

Used in condensed matter physics, particle physics, and quantum optics.
