Production of surface plasmons in electron emission from Al nanoparticles
(Elsevier, 2014-05)
In this work we study the surface plasmon generation by a suddenly created electron-hole pair in nanoparticles of spherical shape. We use a previously developed model based on the Hamiltonian formulation for plasmon field.
Towards coherent optical control of a single hole spin: Rabi rotation of a trion conditional on the spin state of the hole
(Pergamon-Elsevier B.V. Ltd, 2009-09-01)
A hole spin is a potential solid-state q-bit, that may be more robust against nuclear spin induced dephasing than an electron spin. Here we propose and demonstrate the sequential preparation, control and detection of a ...

Charge transfer mechanism of WO3/TiO2 heterostructure for photoelectrochemical water splitting
(2017-04-15)
The present study shows how electronic parameters (e.g. band gap energy, band edge positions) on semiconductors affect photoelectrochemical activity in simulated solar light using WO3, TiO2 and WO3/TiO2 as model systems. ...
Effects of the electron–hole pair in Auger and X-ray photoemission spectroscopy from surfaces of Fe–Si
(Elsevier Science, 2015-02)
In this work, we investigate in detail the effects due to the interaction between an electron and a stationary positive ion (or atomic hole) in the neighborhood of a surface of Fe–Si, having a strong plasmon peak in their ...
Supermassive black hole binaries at high energies
(World Scientific, 2014-03)
An accretion disk around a supermassive black hole may be strongly perturbed by the presence of a secondary black hole. Recent simulations have shown that, under certain conditions, the tidal torques exerted by the secondary ...
Structure control of poly(p-phenylene vinylene) in layer-by-layer films by deposition on a charged poly(o-methoxyaniline) cushion
(2013-04-14)
In this paper, we demonstrate that the intrinsic electric field created by a poly(o-methoxyaniline) (POMA) cushion layer hinders the changes in molecular conformation of poly(p-phenylenevinylene) (PPV) in layer-by-layer ...
Light-hole transitions in quantum dots: Realizing full control by highly focused optical-vortex beams
(American Physical Society, 2014-09)
An optical vortex is an inhomogeneous light beam having a phase singularity at its axis, where the intensity of the electric and/or magnetic field may vanish. Already well studied are the paraxial beams, which may carry ...
