A note on Verhulst's logistic equation and related logistic maps
(2010)
"We consider the Verhulst logistic equation and a couple of forms of the corresponding logistic maps. For the case of the logistic equation we show that using the general Riccati solution only changes the initial conditions ...
Integrable Abel equations and Vein's Abel equation
(2016)
"We first reformulate and expand with several novel findings some of the basic results in the integrability of Abel equations. Next, these results are applied to Vein's Abel equation whose solutions are expressed in terms ...
Existence of periodic orbits in nonlinear oscillators of Emden-Fowler form
(2016)
"The nonlinear pseudo-oscillator recently tackled by Gadella and Lara is mapped to an Emden-Fowler (EF) equation that is written as an autonomous two-dimensional ODE system for which we provide the phase-space analysis and ...
Traveling kinks in cubic nonlinear Ginzburg-Landau equations
(2012)
"Nonlinear cubic Euler-Lagrange equations of motion in the traveling variable are usually derived from Ginzburg-Landau free energy functionals frequently encountered in several fields of physics. Many authors considered ...
Síntesis y caracterización de materiales compuestos de óxido de grafeno con nanopartículas de plata y con dióxido de titanio
(2011)
"El grafeno es un alótropo de carbono de baja dimensionalidad (2D) descubierto en el 2004. En recientes años, este material ha generado grandes expectativas en muchas de las áreas de investigación desde la ciencia básica ...
Optimization of entanglement using genetic algorithms
(2012)
"En tiempos recientes la búsqueda de un modelo más general de computación derivó finalmente en el concepto de la computadora cuántica, un esquema de procesamiento de información basado totalmente en fenómenos cuánticos. ...
One-parameter families of supersymmetric isospectral potentials from Riccati solutions in function composition form
(2014)
"In the context of supersymmetric quantum mechanics, we define a potential through a particular Riccati solution of the composition form (F ◦ f)(x) = F(f(x)) and obtain a generalized Mielnik construction of one-parameter ...
Nongauge bright soliton of the nonlinear Schrödinger (NLS) equation and a family of generalized NLS equations
(2016)
"We present an approach to the bright soliton solution of the nonlinear Schrödinger (NLS) equation from the standpoint of introducing a constant potential term in the equation. We discuss a "nongauge" bright soliton for ...
Inhomogeneous barotropic FRW cosmologies with constant-shifted conformal hubble parameters
(2013)
"It is known that the barotropic FRW system of differential equations for zero cosmological constant can be reduced to simple harmonic oscillator (HO) differential equations in the conformal time variable. This is due to ...
Note on Hawking-Unruh effects in graphene
(2012)
"Beltrami-shaped graphene sheets have been recently proposed as analogs of curved spacetimes with Hawking-Unruh e?ects detected through typi-cal condensed matter measurements involving scanning tunneling micro-scopes and ...
