Changes in the Earth’s magnetic field can deeply modify the polar caps and auroral zones, which are the regions of most frequent precipitation of energetic particles. The present field is characterized by a dominant dipole ...

We study polarization switching and hysteresis in a vertical-cavity surface-emitting laser (VCSEL) subject to an orthogonal optical injection, such that the polarization of the injected light is perpendicular to that of ...

We analyze the characteristics of polarity in unsupported nanoribbons with zigzag edges, by a combination of analytic models, semiempirical Hartree-Fock simulations, and first-principles approach. We consider two materials ...

The purpose of this study is to characterize the corrosion product on the surface of silver, employing H2SO4 (0.5M) as electrolyte. The electrochemical parameters, Ecor, Icor, V cor and Rp were obtained after analyzing the ...

Grazing scattering of neutral atoms from insulator surfaces is investigated in the intermediate velocity range, in which interference effects have recently been observed. To describe this process we introduce a distortedwave ...

The vibrational spectrum of FCC metal vicinal surfaces is obtained from displacement-displacement Green's functions. Results are presented for the Pt(332) surface. Surface spectral densities are calculated, in the neighbourhood ...

We study the dynamics of a vertical-cavity surface-emitting laser (VCSEL) with continuous-wave (cw) orthogonal optical injection from a tunable laser. We use the dynamical properties of polarization bistability and the ...

Surface-relief gratings are photoinscribed on ionically adsorbed layer-by-layer (LBL) films of an azodye, Brilliant Yellow (BY), which was layered alternately with a polyelectrolyte. Photoinscription is performed by impinging ...
