Aggregation and fragmentation dynamics of inertial particles in chaotic flows (2008)
Zahnow, Jens C., Vilela, Rafael D., Feudel, Ulrike, Tel, Tamas
Inertial particles advected in chaotic flows often accumulate in strange attractors. While moving in these fractal sets they usually approach each other and collide. Here we consider inertial...
Poincare recurrences and transient chaos in systems with leaks (2008)
Altmann, Eduardo G., Tel, Tamas
In order to simulate observational and experimental situations, we consider a leak in the phase space of a chaotic dynamical system. We obtain an expression for the escape rate of the survival...
Poincare recurrences from the perspective of transient chaos (2007)
Altmann, Eduardo G., Tel, Tamas
We obtain a description of the Poincar\'e recurrences of chaotic systems in terms of the ergodic theory of transient chaos. It is based on the equivalence between the recurrence time distribution and...
Universality in active chaos (2004)
Tel, Tamas, Nishikawa, Takashi, Motter, Adilson E., Grebogi, Celso, Toroczkai, Zoltan
Many examples of chemical and biological processes take place in large-scale environmental flows. Such flows generate filamental patterns which are often fractal due to the presence of chaos in the...
Reply to E.G.D. Cohen, L. Rondoni, Physica A 306 (2002) 117 (2002)
Tel, Tamas, Vollmer, Juergen, Matyas, Laszlo
In their paper Cohen and Rondoni severely question the physical relevance of studies of transport by means of multibaker maps and other classes of dynamics considering the motion of independen...
Chaotic mixing induced transitions in reaction-diffusion systems (2002)
Neufeld, Zoltan, Haynes, Peter H., Tel, Tamas
We study the evolution of a localized perturbation in a chemical system with multiple homogeneous steady states, in the presence of stirring by a fluid flow. Two distinct regimes are found as the...
Escape-rate formalism, decay to steady states, and divergences in the entropy-production rate (2001)
Vollmer, Juergen, Matyas, Laszlo, Tel, Tamas
In summer 1997 we were sitting with Bob Dorfman and a few other friends interested in chaotic systems and transport theory on a terrace close to Oktogon in Budapest. While taking our (decaf) coffee...
A multibaker map for shear flow and viscous heating (2001)
Matyas, Laszlo, Tel, Tamas, Vollmer, Juergen
A consistent description of shear flow and the accompanied viscous heating as well the associated entropy balance is given in the framework of a deterministic dynamical system. A laminar shear flow...
Shear flow, viscous heating, and entropy balance from dynamical systems (2000)
Tel, Tamas, Vollmer, Juergen, Matyas, Laszlo
A consistent description of a shear flow, the accompanied viscous heating, and the associated entropy balance is given in the framework of a deterministic dynamical system, where a multibaker...
Modelling thermostatting, entropy currents and cross effects by dynamical systems (2000)
Vollmer, Juergen, Tel, Tamas, Matyas, Laszlo
A generalized multibaker map with periodic boundary conditions is shown to model boundary-driven transport, when the driving is applied by a ``perturbation'' of the dynamics localised in a...
A MultiBaker Map for Thermodynamic Cross-Effects in Dynamical Systems (1999)
Matyas, Laszlo, Tel, Tamas, Vollmer, Jurgen
A consistent description of simultaneous heat and particle transport, including cross effects, and the associated entropy balance is given in the framework of a deterministic dynamical system. This...
Thermodynamic Cross-Effects from Dynamical Systems (1999)
Matyas, Laszlo, Tel, Tamas, Vollmer, Jurgen
We give a thermodynamically consistent description of simultaneous heat and particle transport, as well as of the associated cross-effects, in the framework of a chaotic dynamical system, a...
The multifractal structure of chaotically advected chemical fields (1999)
Neufeld, Zoltan, Lopez, Cristobal, Hernandez-Garcia, Emilio, Tel, Tamas
The structure of the concentration field of a decaying substance produced by chemical sources and advected by a smooth incompressible two-dimensional flow is investigated. We focus our attention on...
