Tailoring one-dimensional layered metamaterials to achieve unidirectional transmission and reflection
D. Psiachos, M. M. Sigalas
We investigate elastic-wave propagation in a spatially-dispersive multilayered, totally passive metamaterial system. At oblique incidence a longitudinal (acoustic) wave can convert…

Correlated-electron description of the photophysics of thin films of -conjugated polymers
D. Psiachos, S. Mazumdar
We extend Mulliken's theory of ground state charge transfer in a donor-acceptor complex to excited state charge transfer between pairs of identical -conjugated oligomers, one of…

Electron-electron interaction effects on the photophysics of metallic single-walled carbon nanotubes
Zhendong Wang, Demetra Psiachos, Roberto F. Badilla +1
Single-walled carbon nanotubes are strongly correlated systems with large Coulomb repulsion between two electrons occupying the same orbital. Within a molecular Hamiltonian a…
