Periodically Driven Quantum Thermal Machines from Warming up to Limit Cycle. [PDF]
Physical Review Letters, 2021 Theoretical treatments of periodically driven quantum thermal machines (PD-QTMs) are largely focused on the limit-cycle stage of operation characterized by a periodic state of the system.

Suppression of limit cycle oscillations using the nonlinear tuned vibration absorber. [PDF]
Proc Math Phys Eng Sci, 2015 The objective of this study is to mitigate, or even completely eliminate, the limit cycle oscillations in mechanical systems using a passive nonlinear absorber, termed the nonlinear tuned vibration absorber (NLTVA).

Global computation of phase-amplitude reduction for limit-cycle dynamics. [PDF]
Chaos, 2018 Recent years have witnessed increasing interest in phase-amplitude reduction of limit-cycle dynamics. Adding an amplitude coordinate to the phase coordinate allows us to take into account the dynamics transversal to the limit cycle and thereby overcome ...

Chemical Systems with Limit Cycles
Bulletin of Mathematical Biology, 2023 AbstractThe dynamics of a chemical reaction network (CRN) is often modeled under the assumption of mass action kinetics by a system of ordinary differential equations (ODEs) with polynomial right-hand sides that describe the time evolution of concentrations of chemical species involved. Given an arbitrarily large integer $$K \in {\mathbb N}$$

LIMIT CYCLE BIFURCATIONS IN DISCONTINUOUS PLANAR SYSTEMS WITH MULTIPLE LINES
, 2020 In this paper, the limit cycle bifurcation problem is investigated for a class of planar discontinuous perturbed systems with n parallel switch lines. Under the assumption that the unperturbed system has a family of periodic orbits crossing all of the ...

Isochronicity and limit cycle oscillation in chemical systems [PDF]
Journal of Mathematical Chemistry, 2017 Chemical oscillation is an interesting nonlinear dynamical phenomenon which arises due to complex stability condition of the steady state of a reaction far away from equilibrium which is usually characterised by a periodic attractor or a limit cycle ...

A Variational Method for Analyzing Stochastic Limit Cycle Oscillators [PDF]
SIAM Journal on Applied Dynamical Systems, 2017 We introduce a variational method for analyzing limit cycle oscillators in $\mathbb{R}^d$ driven by Gaussian noise. This allows us to derive exact stochastic differential equations (SDEs) for the amplitude and phase of the solution, which are accurate ...

Cubic nonlinear differential system, their periodic solutions and bifurcation analysis
AIMS Mathematics, 2021 In this article, periodic solutions from a fine focus $ U = 0 $, are accomplished for several classes. Some classes have polynomial coefficients, while the remaining classes $ C_{14, 7} $, $ C_{16, 8} $ and $ C_{5, 5}, $ $ C_{6, 6} $ have non-homogeneous

Dynamic behavior in a three coupled Kaldor-Kalecki delayed model [PDF]
Mathematics and Modeling in Finance, 2022 In this paper, a three coupled Kaldor-Kalecki model with multiple delays is investigated. By means of the generalized Chafee's criterion, some sufficient conditions to guarantee the existence of oscillatory solution for the model are obtained.
