Convergence of the Mayer Series via Cauchy Majorant Method with Application to the Yukawa Gas in the Region of Collapse
Leonardo F. Guidi, Domingos H. U. Marchetti
We construct majorant functions for the Mayer series of pressure satisfying a nonlinear differential equation of first order which can be solved by the method of character…

Combinatorial Solution of One-Dimensional Quantum Systems
Domingos H. U. Marchetti, Claudio F. S. Rodrigues
We give a self-contained exposition of the combinatorial solution of quantum mechanical systems of coupled spins on a one-dimensional lattice. Using Trotter formula, we write the p…
