Ferrimagnetic and Haldane-type phases in a mixed-spin $1$-$\frac{1}{2}$-$\frac{1}{2}$ quantum trimer chain

A. Felinto, R. R. Montenegro-Filho

Bipartite Lieb-Mattis ferrimagnetism and the symmetry-protected Haldane phase are paradigmatic mechanisms in quasi-one-dimensional quantum magnets. Both emerge, in distinct regimes…
