Superfluidity of dipolar excitons in a double layer of with a mass term
Oleg L. Berman, Godfrey Gumbs, Gabriel P. Martins +1
We predict Bose-Einstein condensation and superfluidity of dipolar excitons, formed by electron-hole pairs in spatially separated gapped hexagonal (GHAT3) layers. In the…
Adjustable propagating plasmons in lattice-based armchair nanoribbons
Andrii Iurov, Liubov Zhemchuzhna, Paula Fekete +5
We have obtained and analyzed the electronic states, polarization function and the plasmon excitations for -based nanoribbons with armchair termination. The calcu…
Defect capturing and charging dynamics and their effects on magneto-transport of electrons in quantum wells
Andrii Iurov, Danhong Huang, Godfrey Gumbs +2
The defect corrections to polarization and dielectric functions of Bloch electrons in quantum wells are first calculated. Following this, we derive the first two moment equations f…
Anomalous Klein paradox due to misalignment of optically-tunable elliptical dispersion for Dirac-cone dressed states and direction of incoming particles
Andrii Iurov, Liubov Zhemchuzhna, Paula Fekete +2
After having derived boundary conditions for dressed-state electrons in a dice lattice, we investigate the electron tunneling through a square electrostatic potential barrier in bo…
Electronic properties of closed cage nanometer-size spherical graphitic particles
Godfrey Gumbs, Antonios Balassis, Andrii Iurov +1
We investigate the localization of charged particles by the image potential of spherical shells, such as fullerene buckyballs. These "spherical image states" exist within surface p…
