Rashba spin-orbit coupling and quantum-interference effect for a pair of spin-correlated electrons in their tunneling and reflection under a step potential
Po-Hsin Shih, Godfrey Gumbs, Danhong Huang +2
We present both theory and numerical-computation results for the transmission and reflection probability currents of a charged particle across a potential step in the presence of a…
Finite-temperature plasmons, damping and collective behavior for model
Andrii Iurov, Liubov Zhemchuzhna, Godfrey Gumbs +3
We have conducted a thorough theoretical and numerical investigation of the electronic susceptibility, polarizability, plasmons, their damping rates, as well as the static screenin…
Superfluidity of dipolar magnetoexcitons in doped double-layered - lattice in a strong magnetic field
Yonatan Abranyos, Oleg L. Berman, Godfrey Gumbs
We predict the occurrence of Bose-Einstein condensation and superfluidity of dipolar magnetoexcitons for a pair of quasi-two-dimensional spatially separated - layers…
Interplay of hybrid and unhybrid quantum transport of interacting electron pairs through a short conduction channel
Danhong Huang, Godfrey Gumbs, Yonatan Abranyos +2
For quantum ballistic transport of electrons through a short conduction channel, the role of Coulomb interaction may significantly modify the energy levels of an electron pair at l…
Second Harmonic Generation in Gapped Graphene
Godfrey Gumbs, Yonatan Abranyos, Upali Aparajita +1
The second-order nonlinear optical susceptibility for second harmonic generation is calculated for gapped graphene. The linear and second-order nonlinear plasmon excitati…
Spin-dependent Scattering by a Potential Barrier on a Nanotube
Yonatan Abranyos, Godfrey Gumbs, Paula Fekete
The electron spin effects on the surface of a nanotube have been considered through the spin-orbit interaction (SOI), arising from the electron confinement on the surface of the na…
Degree of entanglement in a quantum measurement process
Matthias Jakob, Yonatan Abranyos, Janos A. Bergou
We suggest a quantum measurement model in an ion trap which specifies the probability distribution of two, distinct internal ground states of a trapped four-level ion. The external…
