A class of generalised Jordan-Schwinger maps
N M Oliveira-Neto, E M F Curado, M A Rego-Monteiro
In this article we introduce a class of generalisations of the Jordan-Schwinger (JS) map which realises the recent proposed generalised sl(2) (G-sl(2)) algebra via two independent…
Consequences of the H-Theorem from Nonlinear Fokker-Planck Equations
Veit Schwammle, Fernando D. Nobre, Evaldo M. F. Curado
A general type of nonlinear Fokker-Planck equation is derived directly from a master equation, by introducing generalized transition rates. The H-theorem is demonstrated for system…
A General Nonlinear Fokker-Planck Equation and its Associated Entropy
Veit Schwammle, Evaldo M. F. Curado, Fernando D. Nobre
A recently introduced nonlinear Fokker-Planck equation, derived directly from a master equation, comes out as a very general tool to describe phenomenologically systems presenting…
Generalized Heisenberg Algebras and Fibonacci Series
J. de Souza, E. M. F. Curado, M. A. Rego-Monteiro
We have constructed a Heisenberg-type algebra generated by the Hamiltonian, the step operators and an auxiliar operator. This algebra describes quantum systems having eigenvalues o…
