Dynamic variational study of chaos: spin glasses in three dimensions

, 2018
We have introduced a variational method to improve the computation of integrated correlation times in the Parallel Tempering Dynamics, obtaining a better estimate (a lower bound, at least) of the exponential correlation time.

Indicators of Chaos

, 2008
Chaotic phenomena are getting interest in all spheres of knowledge. In the past there were certain tools to identify regular and chaotic motions in dynamical systems such as time series curves, phase plots, Poincare maps, power spectra, Lyapunov ...

Optimization of dynamics indicators in pendular systems

Lyapunov exponents have been utilized extensively in the detection of chaos and stability. Various alternatives, such as finite-time Lyapunov exponents and Lagrangian descriptors, have been recently proposed with the objective of reducing the ...

Theory and applications of Fast Lyapunov Indicators for the computation of transit orbits in the three-body problem

, 2021
In the last decades finite time chaos indicators have been used to compute the phase-portraits of complex dynamics as well as the center, stable and unstable manifolds originating at the partially hyperbolic equilibria, and the Lagrangian Coherent ...

Chaoticus: a parallel approach to the computation of chaos indicators

In this paper we present Chaoticus, a Python-based package for the GPU-accelerated integration of ODE systems and the computation of chaos indicators, including SALI, GALI, Lagrangian Descriptors based indicators and the Lyapunov exponent spectrum. By leveraging GPU parallelization, our package significantly reduces the computation times by several ...

Non-chaotic dynamics for Yang–Baxter deformed $$\text {AdS}_{4}\times \text {CP}^{3}$$ AdS 4 × CP 3 superstrings

European Physical Journal C: Particles and Fields
We explore a novel class of Yang–Baxter deformed $$\hbox {AdS}_{4} \times \hbox {CP}^{3}$$ AdS 4 × CP 3 backgrounds (J High Energy Phys 01:056, 2021) which exhibit a non-chaotic dynamics for (super)strings propagating over it.
