A rigid commensurate host and a defect that switches: vacancies in the frustrated alternating spin-(1, 1/2) Heisenberg chain

R. L. Silva, R. C. Silva, A. R. Pereira

The alternating spin- $(1, \frac{1}{2})$ Heisenberg chain with a frustrating next-nearest-neighbor coupling $J_{2}$ loses its Lieb--Mattis moment through a discontinuous transition to a s…
