Lyapunov exponents and poles in a non Hermitian dynamics
(Pergamon-Elsevier Science Ltd, 2017-06)
By means of expressing volumes in phase space in terms of traces of quantum operators, a relationship between the poles of the scattering matrix and the Lyapunov exponents in a non Hermitian quantum dynamics, is presented. ...
SEARCHING FOR SPECIFIC PERIODIC AND CHAOTIC OSCILLATIONS IN A PERIODICALLY-EXCITED HODGKIN-HUXLEY MODEL

On the perturbation of partially hyperbolic endomorphisms
(Taylor & Francis, 2014-03)
We analyze when partially hyperbolic endomorphisms can be perturbed in order to be close to one with non-zero Lyapunov exponents and with an unique inverse measure. Problems of this nature were already boarded and solved ...
On the dynamics of two-dimensional dissipative discontinuous maps
(2020-02-01)
Some dynamical properties for a dissipative two-dimensional discontinuous standard mapping are considered. The mapping, in action-angle variables, is parameterized by two control parameters; namely, k ≥ 0 controlling the ...
Lyapunov decay in quantum irreversibility
(The Royal Society, 2016-05)
The Loschmidt echo?also known as fidelity?is a very useful tool to study irreversibility in quantum mechanics due to perturbations or imperfections. Many different regimes, as a function of time and strength of the ...
Análisis de la predictibilidad de las concentraciones anuales de PM2.5 en Quito, aplicando la entropía de Kolmogórov-Sinai.
(Escuela Superior Politécnica de Chimborazo, 2019-12-23)
The particulate material of 2.5 microns known as PM2.5 is found in urban air, mainly due to vehicular contamination. The health effects are irreversible because by their size it can permanently lodge in the pulmonary ...
NONLINEAR BEHAVIOR IN BRAY-LIBHAFSKY CHEMICAL REACTION
(Sociedad Chilena de Química, 2008)
Investigando a Dinâmica do Rotor Duplo Pulsado: um laboratório dinâmico para sistemas caóticos discretos com espaço de fase 4D
(Sociedade Brasileira de Física, 2021-03-31)
The study of nonlinear dynamical systems makes it possible to understand, apply and predict phenomena in several areas of scientific knowledge, ranging from meteorology and the dynamics of celestial bodies to population ...
