Replica symmetry breaking solution for the fermionic Ising spin glass and the Ghatak-Sherrington model
H. Feldmann, R. Oppermann
We solve the fermionic version of the Ising spin glass for arbitrary filling μand temperature T taking into account replica symmetry breaking. Using a simple exact mapping from μto…
Study of the Potts Model on the Honeycomb and Triangular Lattices: Low-Temperature Series and Partition Function Zeros
H. Feldmann, A. J. Guttmann, I +3
We present and analyze low-temperature series and complex-temperature partition function zeros for the -state Potts model with on the honeycomb lattice and on the…
Complex-Temperature Partition Function Zeros of the Potts Model on the Honeycomb and Kagomé Lattices
Heiko Feldmann, Robert Shrock, Shan-Ho Tsai
We calculate complex-temperature (CT) zeros of the partition function for the -state Potts model on the honeycomb and kagomé lattices for several values of . These give infor…
A Mapping Relating Complex and Physical Temperatures in the 2D -state Potts Model and Some Applications
Heiko Feldmann, Robert Shrock, Shan-Ho Tsai
We show an exact equivalence of the free energy of the -state Potts antiferromagnet on a lattice for the full temperature interval and the free energy o…
