Integrable and Chaotic 4-Dimensional Lotka-Volterra Models and Population Sustainability
H. Christodoulidi, T. E. Kouloukas, L. B. Drossos +1
We examine a 4-dimensional generalization of predator-prey models describing interactions among four species. We show that these systems exhibit a rich variety of asymptotic behavi…
On the Fractional Dynamics of Kinks in sine-Gordon Models
T. Bountis, J. Cantisán, J. Cuevas-Maraver +2
In the present work we explore the dynamics of single kinks, kink-anti-kink pairs and bound states in the prototypical fractional Klein-Gordon example of the sine-Gordon equation.…
The Dissipative Effect of Caputo--Time-Fractional Derivatives and its Implications for the Solutions of Nonlinear Wave Equations
Tassos Bountis, Julia Cantisán, Jesús Cuevas-Maraver +2
In honor of the great Russian mathematician A. N. Kolmogorov, we would like to draw attention in the present paper to a curious mathematical observation concerning fractional diffe…
Spectral Signatures of Exceptional Points and Bifurcations in the Fundamental Active Photonic Dimer
Yannis Kominis, Vassilios Kovanis, Tassos Bountis
The fundamental active photonic dimer consisting of two coupled quantum well lasers is investigated in the context of the rate equation model. Spectral transition properties and ex…
Controllable Asymmetric Phase-Locked States of the Fundamental Active Photonic Dimer
Yannis Kominis, Vassilios Kovanis, Tassos Bountis
Coupled semiconductor lasers are systems possessing complex dynamics that are interesting for numerous applications in photonics. In this work, we investigate the existence and the…
Stability Through Asymmetry: Modulationally Stable Nonlinear Supermodes of Asymmetric non-Hermitian Optical Couplers
Yannis Kominis, Tassos Bountis, Sergej Flach
We analyze the stability of a non-Hermitian coupler with respect to modulational inhomogeneous perturbations in the presence of unbalanced gain and loss. At the parity-time (PT) sy…
