Critical behavior of the classical spin-1 Ising model: a combined low-temperature series expansion and Metropolis Monte Carlo analysis
Amir Taheridehkordi, Roberto Zivieri
In this paper, we theoretically study the critical properties of the classical spin-1 Ising model using two approaches: 1) the analytical low-temperature series expansion and 2) th…
Algorithmic approach to diagrammatic expansions for real-frequency evaluation of susceptibility functions
Amir Taheridehkordi, S. H. Curnoe, J. P. F. LeBlanc
We systematically generate the perturbative expansion for the two-particle spin susceptibility in the Feynman diagrammatic formalism and apply this expansion to a model system - th…
Optimal grouping of arbitrary diagrammatic expansions via analytic pole structure
Amir Taheridehkordi, S. H. Curnoe, J. P. F. LeBlanc
We present a general method to optimize the evaluation of Feynman diagrammatic expansions, which requires the automated symbolic assignment of momentum/energy conserving variables…
Algorithmic Matsubara Integration for Hubbard-like models
Amir Taheridehkordi, S. H. Curnoe, J. P. F. LeBlanc
We present an algorithm to evaluate Matsubara sums for Feynman diagrams comprised of bare Green's functions with single-band dispersions with local U Hubbard interaction vertices.…
