Dynamical correlations in a dissipative XXZ spin chain preserve early-time transport universality classes (ballistic, KPZ, diffusive) with magnon ballistic features at finite magnetization, but acquire exponential damping at long times under Lindblad evolution.
Three-spin interactions enable maximal concurrence near multicritical points and sustain entanglement for intra-phase quenches in a central spin model.
The non-relativistic version of Sorkin's paradoxical measurement scenario has explicit bounds on signaling, with conditions identified for zero extraneous signaling.
In the large-N limit, spin squeezing torsion yields a nonlinear qubit governed by the two-state Gross-Pitaevskii equation that solves single-input state discrimination on the Bloch sphere.
Lecture notes and accompanying library teach replica tensor network methods to compute circuit-averaged observables in random quantum circuits by mapping them to classical statistical mechanics models.
