Continuous similarity transformation for critical phenomena: Easy-axis antiferromagnetic XXZ model
We apply continuous similarity transformations (CSTs) to the easy-axis antiferromagnetic XXZ model on the square lattice. The CST flow equations are truncated in momentum space by the scaling dimension d so that all contributions with d≤2 are taken into account. The resulting quartic magnon-conservi...
