The fate of the spin polaron in the 1D antiferromagnets

P Wrzosek, A Kłosiński, Y Wang, M Berciu… - SciPost Physics, 2024 - scipost.org
The stability of the spin polaron quasiparticle, well established in studies of a single hole in
the 2D antiferromagnets, is investigated in the 1D antiferromagnets using a $ t $-$ J …
