Deconfined criticality flow in the Heisenberg model with ring-exchange

Kun Chen, Yuan Huang, Youjin Deng, A. B. Kuklov, N. V. Prokof'ev, B. V. Svistunov
Quantum transition points in the JQ model -- the testbed of the Deconfined Criticality theory - and the SU(2)-symmetric discrete NCCP$^1$ representation of the deconfined critical action are directly compared by the flowgram method. We find that the flows of two systems coincide in a broad region of linear system sizes ($10View original:
