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…
Transport control in deterministic ratchet system
Woo-Sik Son, Jung-Wan Ryu, Dong-Uk Hwang +3
We study the control of transport properties in a deterministic inertia ratchet system via the extended delay feedback method. A chaotic current of a deterministic inertia ratchet…
Survival probability time distribution in dielectric cavities
Jung-Wan Ryu, Soo-Young Lee, Chil-Min Kim +1
We study the survival probability time distribution (SPTD) in dielectric cavities. In a circular dielectric cavity the SPTD has an algebraic long time behavior, in bo…
Scarred Resonances and Steady Probability Distribution in a Chaotic Microcavity
Soo-Young Lee, Jung-Wan Ryu, Tae-Yoon Kwon +2
We investigate scarred resonances of a stadium-shaped chaotic microcavity. It is shown that two components with different chirality of the scarring pattern are slightly rotated in…
Quasi-Scarred Resonances in a Spiral-Shaped Microcavity
Soo-Young Lee, Sunghwan Rim, Jung-Wan Ryu +3
We study resonance patterns of a spiral-shaped dielectric microcavity with chaotic ray dynamics. Many resonance patterns of this microcavity, with refractive indices and 3, e…
