Ising transition in dimerized XY quantum spin chain
Fei Ye, Guo-Hui Ding, Bo-Wei Xu
In the present paper, we proposed a simple spin-1/2 model which provides a exactly solvable example to study the Ising criticality with central charge c=1/2. By mapping it onto the…

The Ising Transition in the double-frequency sine-Gordon model
Fei Ye, Guo-Hui Ding, Bo-Wei Xu
In the present paper we utilize the renormalization group(RG) technique to analyse the Ising critical behavior in the double frequency sine-Gordon model. The one-loop RG equations…
