Query: Controlled Creation of Quantum Skyrmions   We study the creation of quantum skyrmions in quadratic nanoscopic lattices
of quantum spins coupled by Dzyaloshinkii-Moriya and exchange interactions. We
numerically show that different kinds of quantum skyrmions, characterized by
the magnitude of their spin expectation values and strong differences in their
stability, can appear as ground state and as metastable excitations. In
dependence on the coupling strengths and the lattice size, an adiabatic
rotation scheme of the magnetization at the lattice boundaries allows for a
controlled creation of quantum skyrmions.
