Initial stage of the active mode-locking in semiconductor heterolasers

We make an attempt to develop a novel approach to describing the initial stage of the active mode-locking in semiconductor laser structures based on analyzing the properties of dispersion relations in terms of stability for small initial perturbations. Nonlinear process of shaping optical pulses is interpreted as manifesting instability of diffusion type. For the purposes of experimental invest...

page translation and stage translation of drama texts

نمایشنامه به پیروی از ماهیت دوگانه اش، کارکردی دوگانه به خود می گیرد، بدین معنا که در هر دو نظام ادبی و تئاتری می تواند کارکردی مختص به خود یابد. هدف از انجام این پژوهش یافتن تفاوت ها میان ترجمه صفحه و ترجمه صحنه است.. پرسش مطرح شده عبارتست از: بر اساس مدل ارائه شده توسط لدوسر (1995)، تفاوت های ترجمه صفحه و ترجمه صحنه در چیست؟ یافته های این پژوهش حاکی از آن است که ترجمه صفحه به نمایشنامه ا...

Metal-Insulator Transitions at Surfaces

Various types of metal-insulator transitions are discussed to find conditions for which an ideal surface of a bulk insulator is metallic. It is argued that for the correlation-driven Mott metal-insulator transition the surface phase diagram should be expected to have the same topology as the phase diagram for magnetic order at surfaces: The corresponding linearized mean-field descriptions, a si...

Magnetoelectric coupling at metal surfaces.

Magnetoelectric coupling allows the magnetic state of a material to be changed by an applied electric field. To date, this phenomenon has mainly been observed in insulating materials such as complex multiferroic oxides. Bulk metallic systems do not exhibit magnetoelectric coupling, because applied electric fields are screened by conduction electrons. We demonstrate strong magnetoelectric coupli...
