Fisher zeros in the Kallen-Lehmann approach to 3D Ising model
Marco Astorino, Fabrizio Canfora, Gaston Giribet
The distribution of the Fisher zeros in the Kallen-Lehmann approach to three-dimensional Ising model is studied. It is argued that the presence of a non-trivial angle (a cusp) in t…
Minimal duality breaking in the Kallen-Lehman approach to 3D Ising model: a numerical test
Marco Astorino, Fabrizio Canfora, Cristian Martinez +1
A Kallen-Lehman approach to 3D Ising model is analyzed numerically both at low and high temperature. It is shown that, even assuming a minimal duality breaking, one can fix three p…
Kallen-Lehman approach to 3D Ising model
Fabrizio Canfora
A "Kallen-Lehman" approach to Ising model, inspired by quantum field theory a la Regge, is proposed. The analogy with the Kallen-Lehman representation leads to a formula for the fr…
Regge theory and statistical mechanics
F. Canfora, L. Parisi, G. Vilasi
An interesting connection between the Regge theory of scattering, the Veneziano amplitude, the Lee-Yang theorems in statistical mechanics and nonextensive Renyi entropy is addresse…
