Decoherence from Internal Dynamics in Macroscopic Matter-Wave Interferometry
Sang Wook Kim, Hwa-Kyun Park
Usually, decoherence is generated from the coupling with an outer environment. However, a macroscopic object generically possesses its own environment in itself, namely the complic…

Quasibound states at thresholds in multichannel impurity scattering
Sang Wook Kim, Hwa-Kyun Park, H. -S. Sim +1
We investigate the threshold behavior of transmission resonances and quasibound states in the multichannel scattering problems of a one dimensional (1D) time-dependent impurity pot…

Confinement and death of oscillations in coupled chaotic bistable oscillators
Hwa-Kyun Park
In coupled chaotic bistable systems such as Lorenz and Chua oscillators, two-phase domains corresponding to the two lobes of the strange attractor are formed. The dynamics of each…
