Exact solution of the frustrated Potts model with next-nearest-neighbor interactions in one dimension via AI bootstrapping
Weiguo Yin
The one-dimensional (1D) - -state Potts model is solved exactly for arbitrary by analytically block-diagonalizing the original transfer matrix into…

EuAuSb: An odd-parity helical variation on altermagnetism
J. Sears, Juntao Yao, Zhixiang Hu +7
EuAuSb is a triangular-lattice Dirac semimetal in which a topological Hall effect has been observed to develop in association with a magnetically-ordered phase. Our single-crystal…

Phase Switch Driven by the Hidden Half-Ice, Half-Fire State in a Ferrimagnet
Weiguo Yin, A. M. Tsvelik
The notion of "half fire, half ice" was recently introduced to describe an exotic macroscopic ground-state degeneracy emerging in a ferrimagnet under the critical magnetic field, i…
