Quantum dynamics in a spin-1/2 square lattice -- altermagnet
Yang Liu, Shiqi Shao, Saisai He +4
A key feature of the newly discovered altermagnet is that its spin degeneracy is lifted, although it has an antiferromagnetic order and zero net magnetization. In this work, we inv…

1-Form Symmetric Projected Entangled-Pair States
Yi Tan, Ji-Yao Chen, Didier Poilblanc +2
The 1-form symmetry, manifesting as loop-like symmetries, has gained prominence in the study of quantum phases, deepening our understanding of symmetry. However, the role of 1-form…
