Entanglement and interaction in a topological quantum walk
arXiv:1804.01866 · doi:10.21468/SciPostPhys.5.2.019
Abstract
We study the quantum walk of two interacting particles on a line with an interface separating two topologically distinct regions. The interaction induces a localization-delocalization transition of the edge state at the interface. We characterize the transition through the entanglement between the two particles.
