The entanglement entropy of SU(N) lattice gauge theory is studied exactly in 1+1 space-time dimensions and in Migdal-Kadanoff approximation in higher dimensional space. The existence of a non-analytical behavior reminiscent of a phase transition for a characteristic size of the entangled region is demonstrated for higher dimensional theories.

  1. Momentum-projected hadron entanglement from lattice-QCD replica correlators

    hep-ph 2026-03 conditional novelty 6.0 of 10

    The vacuum-subtracted Rényi response of a momentum-projected hadron equals 1/(1-n) times the log of a replicated source-sink correlator on the cut geometry divided by the n-th power of the ordinary correlator.

  2. Entanglement entropy by tensor renormalization group approach

    hep-lat 2025-02 conditional novelty 6.0 of 10

    A HOTRG-based algorithm computes entanglement entropy for arbitrary subsystem sizes and recovers the central charge c=0.49997(8) for the critical Ising chain.
