Thermal conduction in classical low-dimensional lattices
Characterizing dynamics with covariant Lyapunov vectors.
A general method to determine covariant Lyapunov vectors in both discrete- and continuous-time dynamical systems is introduced. This allows us to address fundamental questions such as the degree of…
Covariant Lyapunov vectors
Recent years have witnessed a growing interest in covariant Lyapunov vectors (CLVs) which span local intrinsic directions in the phase space of chaotic systems. Here, we review the basic results of…
Solar Wind Electrons Alphas and Protons (SWEAP) Investigation: Design of the Solar Wind and Coronal Plasma Instrument Suite for Solar Probe Plus
The Solar Wind Electrons Alphas and Protons (SWEAP) Investigation on Solar Probe Plus is a four sensor instrument suite that provides complete measurements of the electrons and ionized helium and…
The Evolution and Role of Solar Wind Turbulence in the Inner Heliosphere
The first two orbits of the Parker Solar Probe (PSP) spacecraft have enabled the first in situ measurements of the solar wind down to a heliocentric distance of 0.17 au (or 36 Rs). Here, we present…
Enhanced Energy Transfer Rate in Solar Wind Turbulence Observed near the Sun from Parker Solar Probe
Direct evidence of an inertial-range turbulent energy cascade has been provided by spacecraft observations in heliospheric plasmas. In the solar wind, the average value of the derived heating rate…
Desynchronization in diluted neural networks.
TLDR
The dynamical behavior of a weakly diluted fully inhibitory network of pulse-coupled spiking neurons is investigated, and the paradox is solved by drawing an analogy with the phenomenon of "stable chaos" by observing that the stochasticlike behavior is "limited" to an exponentially long transient.
Heat Conduction in Chains of Nonlinear Oscillators
The approach to nonequilibrium statistical mechanicsthrough the introduction of microscopically time-reversible models has been shown to be rather powerfulin the context of many-particle dynamics…
MAVEN observations of the response of Mars to an interplanetary coronal mass ejection
TLDR
Observations and models both show an enhancement in escape rate of ions to space during the Mars upper atmosphere, ionosphere, and interactions with the Sun and solar wind during an interplanetary coronal mass ejection impact in March 2015.
Alfvénic velocity spikes and rotational flows in the near-Sun solar wind
TLDR
Observations of solar-wind plasma at heliocentric distances of about 35 solar radii reveal an increasing rotational component to the flow velocity of the solar wind around the Sun, peaking at 35 to 50 kilometres per second—considerably above the amplitude of the waves.
