Oscillation death in coupled counter-rotating identical nonlinear oscillators
Jung-Wan Ryu, Woo-Sik Son, Dong-Uk Hwang
We study oscillatory and oscillation suppressed phases in coupled counter-rotating nonlinear oscillators. We demonstrate the existence of limit cycle, amplitude death, and oscillat…
Amplitude death in a ring of nonidentical nonlinear oscillators with unidirectional coupling
Jung-Wan Ryu, Jong-Ho Kim, Woo-Sik Son +1
We study the collective behaviors in a ring of coupled nonidentical nonlinear oscillators with unidirectional coupling, of which natural frequencies are distributed in a random way…
Localization in chaotic systems with a single-channel opening
Domenico Lippolis, Jung-Wan Ryu, Sang Wook Kim
We introduce a single-channel opening in a random Hamiltonian and a quantized chaotic map: localization on the opening occurs as a sensible deviation of the wavefunction statistics…
Exceptional points in coupled dissipative dynamical systems
Jung-Wan Ryu, Woo-Sik Son, Dong-Uk Hwang +2
We study the transient behavior in coupled dissipative dynamical systems based on the linear analysis around the steady state. We find that the transient time is minimized at a spe…
Quasiattractors in coupled maps and coupled dielectric cavities
Jung-Wan Ryu, Martina Hentschel, Sang Wook Kim
We study the origin of attracting phenomena in the ray dynamics of coupled optical microcavities. To this end we investigate a combined map that is composed of standard and linear…
Quasiscarred modes and their branching behavior at an exceptional point
Jung-Wan Ryu, Soo-Young Lee
We study quasiscarring phenomenon and mode branching at an exceptional point (EP) in typically deformed microcavities. It is shown that quasiscarred (QS) modes are dominant in some…
