Universality Class around the SU(3) Symmetric Point of the Dimer–Trimer Spin-1 Chain

J. Phys. Soc. Jpn. 90, 024005 (2021).
We numerically diagonalize the Dimer-Trimer (DT) model Hamiltonian around the SU(3) symmetric point. As a result, we discover the phase transition at this point which belongs to the Berezinskii-Kosterlitz-Thouless (BKT)-like universality class.
