Diode effects in the surface superconductivity regime

the effects of changing roughness on the flow structure in the bends

flow in natural river bends is a complex and turbulent phenomenon which affects the scour and sedimentations and causes an irregular bed topography on the bed. for the reason, the flow hydralics and the parameters which affect the flow to be studied and understand. in this study the effect of bed and wall roughness using the software fluent discussed in a sharp 90-degree flume bend with 40.3cm ...

The Density of Superconductivity in the Bulk Regime

In the asymptotic limit of a large Ginzburg-Landau parameter, we give a new asymptotic formula for the L-norm of the Ginzburg-Landau order parameter. The formula is valid in the bulk regime where the intensity of the applied magnetic eld is of the same order as the Ginzburg-Landau parameter and strictly below the second critical eld. Our formula complements the celebrated one of Sandier-Serfaty...

Approaching the strongly coupled regime of color-superconductivity

Quark matter at sufficiently high density and low temperatures is expected to be a color-superconductor. Due to asymptotic freedom, it can be systematically studied at high densities in a weak coupling expansion [1, 2]. At low densities, i.e. in the strongly coupled regime, such an expansion is lacking. Therefore non-perturbative methods such as truncated Dyson-Schwinger equations have to be ap...

the study of bright and surface discrete cavity solitons dynamics in saturable nonlinear media

امروزه سالیتون ها بعنوان امواج جایگزیده ای که تحت شرایط خاص بدون تغییر شکل در محیط منتشر می-شوند، زمینه مطالعات گسترده ای در حوزه اپتیک غیرخطی هستند. در این راستا توجه به پدیده پراش گسسته، که بعنوان عامل پهن شدگی باریکه نوری در آرایه ای از موجبرهای جفت شده، ظاهر می گردد، ضروری است، زیرا سالیتون های گسسته از خنثی شدن پراش گسسته در این سیستم ها بوسیله عوامل غیرخطی بوجود می آیند. گسستگی سیستم عامل...
