Theory of short periodic orbits for partially open quantum maps
(American Physical Society, 2016-07)
We extend the semiclassical theory of short periodic orbits [M. Novaes et al., Phys. Rev. E 80, 035202(R) (2009)] to partially open quantum maps, which correspond to classical maps where the trajectories are partially ...

Orbital-polarization terms: From a phenomenological to a first-principles description of orbital magnetism in density-functional theory
(JOHN WILEY & SONS INC, 2008)
Phenomenological orbital-polarizition (OP) terms have been repeatedly introduced in the single-particle equations of spin-density-functional theory, in order to improve the description of orbital magnetic moments in systems ...
No periodic orbits for the type A Bianchi's systems
(Taylor & Francis Ltd, 2015-01-01)
It is known that the 6 models of Bianchi class A have no periodic solutions. In this article we provide a new, direct, unified and easier proof of this result.
The Lyapunov exponents and the neighbourhood of periodic orbits
(Wiley Blackwell Publishing, Inc, 2020-05)
We show that the Lyapunov exponents of a periodic orbit can be easily obtained from the eigenvalues of the monodromy matrix. It turns out that the Lyapunov exponents of simply stable periodic orbits are all zero, simply ...
Global Dynamics and Bifurcation of Periodic Orbits in a Modified Nosé-Hoover Oscillator
We perform a global dynamical analysis of a modified Nosé-Hoover oscillator, obtained as the perturbation of an integrable differential system. Using this new approach for studying such an oscillator, in the integrable ...
