Fock space for fermion-like lattices and the linear Glauber model
(ELSEVIER SCIENCE BV, 2008)
The concept of Fock space representation is developed to deal with stochastic spin lattices written in terms of fermion operators. A density operator is introduced in order to follow in parallel the developments of the ...
The lattice of trumping majorization for 4D probability vectors and 2D catalysts
(Nature Publishing Group, 2018-12)
The transformation of an initial bipartite pure state into a target one by means of local operations and classical communication and entangled-assisted by a catalyst defines a partial order between probability vectors. ...
A lattice gas of prime numbers and the Riemann Hypothesis
(Elsevier Science, 2013-10)
In recent years, there has been some interest in applying ideas and methods taken from Physics in order to approach several challenging mathematical problems, particularly the Riemann Hypothesis. Most of these kinds of ...
Representations of cubic lattices by symmetric implication algebras
(Springer, 2006-10-18)
In this paper a cubic lattice L(S) is endowed with a symmetric implication structure and it is proved that L(S) \ {0} is a power of the three-element simple symmetric implication algebra. The Metropolis–Rota’s symmetries ...
A numerical study of progressive damage in unidirectional composite materials using a 2D lattice model
(Pergamon-Elsevier Science Ltd, 2021-05)
In this study, we explored the effects of different softening laws on the modelling of progressive damage in unidirectional composites materials using a 2D lattice model. The lattice model was based on axial springs that ...
