Exactly Solvable Models for Altermagnetic Spin Liquids
Analysis
This paper introduces exactly solvable models for a novel phase of matter called an altermagnetic spin liquid. The models, based on spin-3/2 and spin-7/2 systems on specific lattices, allow for detailed analysis of these exotic states. The work is significant because it provides a theoretical framework for understanding and potentially realizing these complex quantum phases, which exhibit broken time-reversal symmetry but maintain other symmetries. The study of these models can help to understand the interplay of topology and symmetry in novel phases of matter.
