Relation between Magnitude Series Correlations and Multifractal Spectrum Width
Yosef Ashkenazy, Shlomo Havlin, Plamen Ch. Ivanov +3
We study the correlation properties of long-range correlated time series, , with tunable correlation exponent and built-in multifractal properties. For the cases we investigat…
Decomposition of Heartbeat Time Series: Scaling Analysis of the Sign Sequence
Y. Ashkenazy, P. Ch. Ivanov, S. Havlin +4
The cardiac interbeat (RR) increment time series can be decomposed into two sub-sequences: a magnitude series and a sign series. We show that the sign sequence, a simple binary rep…
Chaotic enhancement of decay. The effect of classical phase space structure
Yosef Ashkenazy, Luca Bonci, Jacob Levitan +1
We investigate the decay process from a time dependent potential well in the semiclassical regime. The classical dynamics is chaotic and the decay rate shows an irregular behavior…
The Radiative Kicked Oscillator: A Stochastic Web or Chaotic Attractor ?
Y. Ashkenazy, L. P. Horwitz
A relativistic charged particle moving in a uniform magnetic field and kicked by an electric field is considered. Under the assumption of small magnetic field, an iterative map is…
Chaos and Maps in Relativistic Dynamical Systems
L. P. Horwitz, Y. Ashkenazy
The basic work of Zaslavskii et al showed that the classical non-relativistic electromagnetically kicked oscillator can be cast into the form of an iterative map on the phase space…
The Effect of Radiation on the Stochastic Web
Y. Ashkenazy, L. P. Horwitz
A charged particle circling in a uniform magnetic field and kicked by an electric field is considered. Under the assumption of small magnetic field, an iterative map is developed.…
