Dispersion and transitions of dipolar plasmon modes in graded plasmonic waveguides
J. J. Xiao, K. Yakubo, K. W. Yu
Coupled plasmon modes are studied in graded plasmonic waveguides, which are periodic chains of metallic nanoparticles embedded in a host with gradually varying refractive indices.…
Optical switching in graded plasmonic waveguides
J. J. Xiao, K. Yakubo, K. W. Yu
A new mechanism of longitudinal confinement of optical energy via coupled plasmon modes is proposed in chains of noble metal nanoparticles embedded in a graded dielectric medium, w…
Harmonic vibrational excitations in graded elastic networks: transition from phonons to gradons
J. J. Xiao, K. Yakubo, K. W. Yu
We have identified a new type of transition from extended to localized vibrational states in one-dimensional graded elastic chains of coupled harmonic oscillators, in which the vib…
Anomalously localized states and multifractal correlations of critical wavefunctions in two-dimensional electron systems with spin-orbital interactions
H. Obuse, K. Yakubo
Anomalously localized states (ALS) at the critical point of the Anderson transition are studied for the SU(2) model belonging to the two-dimensional symplectic class. Giving a quan…
Critical level statistics and anomalously localized states at the Anderson transition
H. Obuse, K. Yakubo
We study the level-spacing distribution function at the Anderson transition by paying attention to anomalously localized states (ALS) which contribute to statistical propert…
Correlation Exponent and Anomalously Localized States at the Critical Point of the Anderson Transition
H. Obuse, K. Yakubo
We study the box-measure correlation function of quantum states at the Anderson transition point with taking care of anomalously localized states (ALS). By eliminating ALS from the…
