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…
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…
Resonance Patterns in a Stadium-shaped Microcavity
Soo-Young Lee, M. S. Kurdoglyan, Sunghwan Rim +1
We investigate resonance patterns in a stadium-shaped microcavity around , where is the refractive index, the vacuum wavenumber, and the radius of t…
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…
Chaos Synchronization of delayed systems in the presence of delay time modulation
Won-Ho Kye, Muhan Choi, Myung-Woon Kim +4
We investigate synchronization in the presence of delay time modulation for application to communication. We have observed that the robust synchronization is established by a commo…
Wavefunction Statistics using Scar States
Soo-Young Lee, Stephen C. Creagh
We describe the statistics of chaotic wavefunctions near periodic orbits using a basis of states which optimise the effect of scarring. These states reflect the underlying structur…
Scarring and the statistics of tunnelling
Stephen C. Creagh, Soo-Young Lee, Niall D. Whelan
We show that the statistics of tunnelling can be dramatically affected by scarring and derive distributions quantifying this effect. Strong deviations from the prediction of random…
