A neutral current protocol on the lattice in the massive Thirring model yields a weak signal exactly matching a coarse-grained current correlator, with extracted energy scaling quadratically with measurement strength, identifying the neutral sector shared with the continuum.
A manifestly BRST-invariant Schwinger-Keldysh path integral is derived for non-Abelian gauge theories with generic initial states, enabling perturbative Ward-Takahashi-Slavnov-Taylor identities and Open EFT expansions that preserve a contracted Keldysh BRST symmetry.
Black hole scrambling suppresses and eventually eliminates late-time entanglement revivals in CFT mutual information for disjoint intervals, with spikes vanishing when interval lengths become exponential in the scrambling time.
In this fuzzy-sphere matrix model the largest Lyapunov exponent drops to zero at finite temperature, respecting the Maldacena-Shenker-Stanford bound while entanglement shows fast scrambling.
The work introduces vector flow and modular flows in celestial field theory and Klein CFTs and examines their structures in Lifshitz and exotic field theories.
