Perturbing Chaos with Cycle Expansions
Huanyu Cao, Yueheng Lan
Due to existence of periodic windows, chaotic systems undergo numerous bifurcations as system parameters vary, rendering it hard to employ an analytic continuation, which constitut…
A reduced variational approach for searching cycles in high-dimensional systems
Ding Wang, Yueheng Lan
Searching recurrent patterns in complex systems with high-dimensional phase spaces is an important task in diverse fields. In the current work, an improved scheme is proposed to ac…
Koopman analysis in oscillator synchronization
Jing Hu, Yueheng Lan
Synchronization is an important dynamical phenomenon in coupled nonlinear systems, which has been studied extensively in recent years. However, analysis focused on individual orbit…
Koopman Operator and Phase Space Partition of Chaotic Maps
Cong Zhang, Yueheng Lan
Koopman operator describes evolution of observables in the phase space, which could be used to extract characteristic dynamical features of a nonlinear system. Here, we show that i…
Analyzing intramolecular dynamics by Fast Lyapunov Indicators
Elena Shchekinova, Cristel Chandre, Yueheng Lan +1
We report an analysis of intramolecular dynamics of the highly excited planar carbonyl sulfide (OCS) below and at the dissociation threshold by the Fast Lyapunov Indicator (FLI) me…
Chaotic Spin Dynamics of a Long Nanomagnet Driven by a Current
Yueheng Lan, Y. Charles Li
We study the spin dynamics of a long nanomagnet driven by an electrical current. In the case of only DC current, the spin dynamics has a sophisticated bifurcation diagram of attrac…
