A mean field approach to multiple, long-delayed systems
Giovanni Giacomelli, Antonio Politi
The concept of multiple, long-delayed feedback systems is introduced and discussed with reference to a paradigmatic model. We analyse how the resulting chaotic dynamics is affected…
Ultra-slow dynamics of free-running ring lasers: towards a minimal model
Giovanni Giacomelli, Antonio Politi
The dynamics of a resonant, free-running ring laser, in the common case of a fast relaxation of the atomic polarization, is unexpectedly highly singular. As shown in [Phys. Rev. Re…
Nearly Hamiltonian dynamics of laser systems
Antonio Politi, Serhiy Yanchuk, Giovanni Giacomelli
The Arecchi-Bonifacio (or Maxwell-Bloch) model is the benchmark for the description of active optical media. However, in the presence of a fast relaxation of the atomic polarizatio…
Spatio-temporal phenomena in complex systems with time delays
Serhiy Yanchuk, Giovanni Giacomelli
Real-world systems can be strongly influenced by time delays occurring in self-coupling interactions, due to unavoidable finite signal propagation velocities. When the delays becom…
Spaceless description of active optical media
Giovanni Giacomelli, Serhiy Yanchuk, Antonio Politi
The acclaimed Maxwell-Bloch (or Arecchi-Bonifacio) equations are a valid dynamical model, effectively describing wave propagation in nonlinear optical media: from the amplification…
Spatio-temporal representation of long-delayed systems: an alternative approach
Francesco Marino, Giovanni Giacomelli
Dynamical systems with long delay feedback can exhibit complicated temporal phenomena, which once re-organized in a two-dimensional space are reminiscent of spatio-temporal behavio…
