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…
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…
Time Delay Effect on the Love Dynamical Model
Woo-Sik Son, Young-Jai Park
We investigate the effect of time delay on the dynamical model of love. The local stability analysis proves that the time delay on the return function can cause a Hopf bifurcation…
Mixmaster universe in the z=3 deformed Hořava-Lifshitz gravity
Yun Soo Myung, Yong-Wan Kim, Woo-Sik Son +1
The z=3 deformed Horava-Lifshitz gravity with coupling constants ωand εleads to a nonrelativistic "mixmaster" cosmological model. The potential of theory is given by the sum of IR…
Chaotic universe in the z=2 Hovava-Lifshitz gravity
Yun Soo Myung, Yong-Wan Kim, Woo-Sik Son +1
The deformed z=2 Horava-Lifshitz gravity with coupling constant w leads to a nonrelativistic "mixmaster" cosmological model. The potential of theory is given by the sum of IR and U…
