A new method to calculate a 2d ising universality transition point : application near the ashkin-teller multicritical point
S. Moriya, K. Nomura
We propose a new method to numerically calculate transition points that belongs to 2D Ising universality class for quantum spin models. Generally, near the multicritical point, in…

Universality Class around the SU(3) Symmetric Point of the Dimer-Trimer Spin-1 Chain
Tohru Mashiko, Shunji Moriya, Kiyohide Nomura
We study critical phenomena of the SU(3) symmetric spin-1 chains when adding the SU(3) asymmetric term. To investigate such system, we numerically diagonalize the Dimer-Trimer (DT)…
