Inverted Berezinskii-Kosterlitz-Thouless Singularity and High-Temperature Algebraic Order in an Ising Model on a Scale-Free Hierarchical-Lattice Small-World Network
Michael Hinczewski, A. Nihat Berker
We have obtained exact results for the Ising model on a hierarchical lattice with a scale-free degree distribution, high clustering coefficient, and small-world behavior. By varyin…

Finite-Temperature Phase Diagram of the Hubbard Model
G. Migliorini, A. N. Berker
The finite-temperature phase diagram of the Hubbard model in is obtained from renormalization-group analysis. It exhibits, around half filling, an antiferromagnetic phase and…
