In these proceedings we give a pedagogical and non-technical introduction to the Quantum Field Theory approach to entanglement entropy. Particular attention is devoted to the one space dimensional case, with a linear dispersion relation, that, at a quantum critical point, can be effectively described by a two-dimensional Conformal Field Theory.

  1. When Renormalisation Remembers: UV/IR Mixing as an Entanglement Bridge

    hep-th 2026-06 unverdicted novelty 8.0 of 10

    Introduces the Born-Reciprocal Tensor Network to realize UV/IR mixing as an entanglement bridge in renormalization geometry, with a large-volume limit restoring standard Wilsonian decoupling.

  2. Dynamical Entanglement Phase Transitions in Holographic CFTs

    hep-th 2026-05 unverdicted novelty 7.0 of 10

    In large-central-charge holographic CFTs, post-quench mutual information organizes into six phases governed by conformal block dominance and D4 symmetry breaking to Z2 x Z2.

  3. Quantum dynamics of cosmological particle production: interacting quantum field theories with matrix product states

    hep-th 2026-01 unverdicted novelty 7.0 of 10

    Self-interactions in scalar and gauge theories suppress gravitational particle production in a quench modeling cosmic expansion, as computed with tensor networks.

  4. Geometric modular flows in 2d CFT and beyond

    hep-th 2025-02 conditional novelty 7.0 of 10

    In 2d CFTs, every suitably regular Unruh flow on the Rindler wedge is the modular flow of a state obtained by a conformal unitary acting on the vacuum or thermal state, and local entropy and stress-tensor formulas follow.

  5. $BMS_3$-like algebras via the $Z_N$-graded $u(1)^2$ Kac-Moody algebra

    hep-th 2026-06 unverdicted novelty 6.0 of 10

    Compactification of the non-compact algebraic varieties of Z_N-graded Sugawara constructions on u(1)^2 Kac-Moody yields BMS3-like algebras Vir ⋊ F with F nilpotent of depth r < N for N>2, with depth tied to singularity order.

  6. Entanglement entropy and $T\bar T$ deformations beyond antipodal points from holography

    hep-th 2019-08 conditional novelty 6.0 of 10

    For a holographic (A)dS spacetime with a hard radial cutoff, the entanglement entropy of any interval on the sphere equals the antipodal-point formula with radius R cos(beta_epsilon).

  7. Testing the ${\rm ER=EPR}$ conjecture with entangled photons

    gr-qc 2026-06 unverdicted novelty 5.0 of 10

    Regularizing the Aichelburg-Sexl metric for entangled photons produces a zero-throat wormhole geometry realizing ER=EPR, with gravitational self-energy scaling as 4G(ℏω)²/(c⁴L) ln(d²/l₀²) and matching an entanglement-...
