Spreading of entanglement and correlations after a quench with intertwined quasiparticles
Spreading of entanglement and correlations after a quench with intertwined quasiparticles
We extend the semiclassical picture for the spreading of entanglement and correlations to quantum quenches with several species of quasiparticles that have non-trivial pair correlations in momentum space. These pair correlations are, for example, relevant in inhomogeneous lattice models with a periodically-modulated Hamiltonian parameter. We provide explicit predictions for the …
