Ground-State Phase Diagram, Higher-Winding Topology, and Lifshitz Criticality in an Anisotropic Four-Spin XX Chain

Mohammad Abbasi, Faraz Valeh, Saeed Mahdavifar

We investigate the quantum critical and topological properties of a spin- XX chain with anisotropic four-spin cluster interactions in a transverse magnetic field. The interpla…
