Permutation defects between wavefunction replicas yield multipartite entanglement measures that capture the chiral central charge from bulk states in chiral topological phases.
Exact computation of logarithmic negativity between arbitrary compact regions in 1+1D massless scalar field vacuum via Kähler structure diagonalization of partially-transposed complex structure, reformulated as complex-plane boundary value problem.
Analytic computation of logarithmic negativity and closed-form negativity cores for vacuum entanglement between two bounded regions in 1+1D free massless scalar QFT.
Algebraic entanglement entropy from type II1 algebras in double-scaled SYK is matched via triple-scaling limits to Ryu-Takayanagi areas in (A)dS2, reproducing Bekenstein-Hawking and Gibbons-Hawking formulas for specific regions while depending on Krylov complexity of the Hartle-Hawking state.
Derives new state-independent lower bounds on semi-local integrals of null energy flux in QFTs of two and higher dimensions using QNEC, strong subadditivity, and modular Hamiltonians.
Derives conditions for TEE probes, generalizes cyclic and multi-information quantities, and verifies holographic entropy inequalities for gapped topological states.
