Propagation of Dirac waves through various temporal interfaces, slabs, and crystals
Seulong Kim, Kihong Kim
We investigate the influence of the temporal variations of various medium parameters on the propagation of Dirac-type waves in materials where the quasiparticles are described by a…
Transport and localization properties of excitations in one-dimensional lattices with diagonal disordered mosaic modulations
Ba Phi Nguyen, Kihong Kim
We present a numerical study of the transport and localization properties of excitations in one-dimensional lattices with diagonal disordered mosaic modulations. The model is chara…
Giant overreflection of magnetohydrodynamic waves from inhomogeneous plasmas with nonuniform shear flows
Seulong Kim, Kihong Kim
We study theoretically mode conversion and resonant overreflection of magnetohydrodynamic waves in an inhomogeneous plane-stratified plasma in the presence of a nonuniform shear fl…
Delocalization and re-entrant localization of flat-band states in non-Hermitian disordered lattice models with flat bands
Sangbum Kim, Kihong Kim
We present a numerical study of Anderson localization in disordered non-Hermitian lattice models with flat bands. Specifically we consider one-dimensional stub and two-dimensional…
Quasi-resonant diffusion of wave packets in one-dimensional disordered mosaic lattices
Ba Phi Nguyen, Duy Khuong Phung, Kihong Kim
We investigate numerically the time evolution of wave packets incident on one-dimensional semi-infinite lattices with mosaic modulated random on-site potentials, which are characte…
Mode conversion and resonant absorption in inhomogeneous materials with flat bands
Kihong Kim, Seulong Kim
Mode conversion of transverse electromagnetic waves into longitudinal oscillations and the associated resonant absorption of wave energy in inhomogeneous plasmas is a phenomenon th…
