Noncommutative geometry induced by spin effects
L. P. Colatto, A. L. A. Penna, W. C. Santos
In this paper we study the nonlocal effects of noncommutative spacetime on simple physical systems. Our main point is the assumption that the noncommutative effects are consequence…
On pairs of matrices generating matrix rings and their presentations
B. V. Petrenko, S. N. Sidki
Let the ring of -by- matrices with integral entries, and . This paper studies the set of pairs gen…
Bethe-Ansatz density-functional theory of ultracold repulsive fermions in one-dimensional optical lattices
Gao Xianlong, Marco Polini, M. P. Tosi +3
We present an extensive numerical study of ground-state properties of confined repulsively interacting fermions on one-dimensional optical lattices. Detailed predictions for the at…
Field Theory Renormalization Group: The Tomonaga-Luttinger Model Revisited
A. Ferraz
We apply field theoretical renormalization group (RG) methods to describe the Tomonaga-Luttinger model as an important test ground to deal with spin-charge separation effects in hi…
A genetic algorithm to build diatomic potentials
Luiz Fernando Roncaratti, Ricardo Gargano, Geraldo Magela e Silva
Several types of numerical and combinatorial optimization algorithms have been used as useful tools to minimize functional forms. Generally, when those forms are non-linear or occu…
Combinatorial Identities and Quantum State Densities of Supersymmetric Sigma Models on N-Folds
M. C. B. Abdalla, A. A. Bytsenko, M. E. X. Guimaraes
There is a remarkable connection between the number of quantum states of conformal theories and the sequence of dimensions of Lie algebras. In this paper, we explore this connectio…
