Abstract
We present a systematic study of the formation of skyrmion crystals in a triangular Kondo Lattice model for generic electron filling fractions. Our results indicate that the four-sublattice chiral antiferromagnetic ordering that was reported more than one decade ago can be understood as the dense limit of a sequence of skyrmion crystals whose lattice parameter is dictated by the Fermi wave-vector. This observation has important implications for the ongoing search of skyrmion crystals in metallic materials with localized magnetic moments.
Author comments upon resubmission
Thank you for having considered our manuscript entitled "Skyrmion Crystals in the Triangular Kondo Lattice Model" for publication in SciPost Physics. Both referees found our results of current interest and sound, and raised concerns that some parts of the manuscript could be explained in further detail. After incorporating all comments and suggestions, we would like to resubmit the manuscript for further consideration.
Below please find the list of changes that have been introduced in the revised manuscript, along with our detailed response to the referees on the submission page. We are convinced that the manuscript will stimulate further theoretical/experimental findings of SkX for the more general conditions pointed out by our paper.
Yours sincerely,
Zhentao Wang and Cristian D. Batista
List of changes
1. We have clarified several ambiguous points in the manuscript, including the nearest neighbor hopping <ij>, the number of trials in the variational calculation, and the validity of the classical moment treatment.
2. We have added discussion to clarify the difference of topological charge $n_{sk}=2$ and $n_{sk}=1$ cases, as pointed out by Referee-1.
3. We have included several references relevant to the topic, including the ones pointed out by Referee-1.
4. We have expanded the text for the introduction, the KPM method, and the variational method, as requested by Referee-2.
