Universality Class around the SU(3) Symmetric Point of the Dimer–Trimer Spin1 Chain
J. Phys. Soc. Jpn. 90, 024005 (2021).
We numerically diagonalize the DimerTrimer (DT) model Hamiltonian around the SU(3) symmetric point. As a result, we discover the phase transition at this point which belongs to the BerezinskiiKosterlitzThouless (BKT)like universality class.

The coupling between surface acoustic waves and spin waves is shown to depend strongly on the angle between the acoustic wavevector and magnetization. For a particular angle, it completely vanishes in one direction, which enables a unidirectional generation of surface acoustic waves by a ferromagnetic resonance.
