ABSTRACT
The time evolution of entanglement in nonequilibrium quantum many-body systems provides a lot of information about the underlying dynamics. Among others, studies of entanglement spreading from highly excited initial states of integrable systems have contributed a lot to our understanding of quasiparticle dynamics. In this talk I will consider the case of low energy excitations above the ground state, created by a local operator, and show that the growth of entanglement can still be characterized by a quasiparticle picture. The case of extended excitations will also be discussed, which interpolates between local and global quench scenarios. |
