Entanglement spreading after local fermionic excitations in the XXZ chain
Matthias Gruber, Viktor Eisler
We study the spreading of entanglement produced by the time evolution of a local fermionic excitation created above the ground state of the XXZ chain. The resulting entropy profile…

Time evolution of entanglement negativity across a defect
Matthias Gruber, Viktor Eisler
We consider a quench in a free-fermion chain by joining two homogeneous half-chains via a defect. The time evolution of the entanglement negativity is studied between adjacent segm…

Magnetization and entanglement after a geometric quench in the XXZ chain
Matthias Gruber, Viktor Eisler
We investigate the dynamics of the XXZ spin chain after a geometric quench, which is realized by connecting two half-chains prepared in their ground states with zero and maximum ma…
