(A) Lattice model for realizing the deconfined quantum phase transition. (B) The phase diagram for the square lattice SU(N) model. Dots represent the quantum phase transition points.

Osaka Metropolitan University physicists present a case study of the critical phenomena around Argyres-Douglas singularity of N = 2 susy made at (𝐴1, 𝐴4𝑘−1), 𝑘=1,2 realized by ...
