Hankel matrices for the period-doubling sequence
Indagationes Mathematicae, 2017 We give an explicit evaluation, in terms of products of Jacobsthal numbers, of the Hankel determinants of order a power of two for the period-doubling sequence. We also explicitly give the eigenvalues and eigenvectors of the corresponding Hankel matrices. Similar considerations give the Hankel determinants for other orders.

Quasi-Discrete Time Crystals in the Quasiperiodically Driven Lipkin–Meshkov–Glick Model [PDF]
EntropyA discrete time crystal (DTC) is a remarkable non-equilibrium phase of matter characterized by the persistent sub-harmonic oscillations of physical observables in periodically driven many-body systems. Motivated by the question of whether such a temporal

Period-doubling in discrete relative spatial dynamics and the Feigenbaum sequence
Mathematical Modelling, 1987 The authors extend investigations of M. Feigenbaum and R. Helleman. They show that the Feigenbaum sequence found in period-doubling cycles of discrete maps and generally attributed to parameters ought to be attributed to the slopes of their corresponding Poincaré maps.

Asymmetry- and Viscosity-Regulated Atomization of Laminar Impinging Microjets: Morphology Map, Modal Dynamics, and Droplet Statistics [PDF]
MicromachinesDespite decades of studies on symmetric impinging-jet atomization, the combined role of controlled pre-impingement asymmetry and viscosity in setting the instability pathways and droplet statistics of laminar microjets remains insufficiently quantified ...

Bifurcations and spectral pulsations in ultrafast fiber lasers [PDF]
EPJ Web of Conferences, 2023 We employ real-time spectral measurements to investigate the transitions from the stable mode locking to period doubling and long-period pulsations. We highlight the role of self-phase modulation as a general mechanism triggering period-2 bifurcations ...

Erbium - doped fiber laser systems: Routes to chaos [PDF]
Serbian Journal of Electrical Engineering, 2014 Erbium-doped fiber laser systems exhibit a large variety of complex dynamical behaviors, bifurcations and attractors. In this paper, the chaotic behavior which can be achieved under certain conditions in a laser system with erbium-doped fiber ...

Open Physics, 2023 In this work, we numerically study the behaviour of the single-mode homogeneously broadened laser versus a large perturbation of the steady state. Periodic behaviour develops for suitable values of the ratio of the population decay rates ℘\wp , which has

Bifurcations and Structures of the Parameter Space of a Discrete-Time SIS Epidemic Model
Journal of Mathematics, 2022 The dynamics of a discrete-time SIS epidemic model are reported in this paper. Three types of codimension one bifurcation, namely, transcritical, flip, Neimark–Sacker (N-S) bifurcations, and their intersection codimension two bifurcations including 1 : 2,
