Findings

Transport of interface states is achievable via adiabatic manipulation.

The adiabatic constant depends on magnetic field strength and anisotropy.

Numerical DMRG confirms theoretical predictions.

Abstract

We demonstrate the transport of interface states in the one-dimensional ferromagnetic Heisenberg model by a time dependent magnetic field. Our analysis is based on the standard Adiabatic Theorem. This is supplemented by a numerical analysis via the recently developed time dependent DMRG method, where we calculate the adiabatic constant as a function of the strength of the magnetic field and the anisotropy of the interaction.
