control of the optical properties of nanoparticles by laser fields
در این پایان نامه، درهمتنیدگی بین یک سیستم نقطه کوانتومی دوگانه(مولکول نقطه کوانتومی) و میدان مورد مطالعه قرار گرفته است. از آنتروپی ون نیومن به عنوان ابزاری برای بررسی درهمتنیدگی بین اتم و میدان استفاده شده و تاثیر پارامترهای مختلف، نظیر تونل زنی(که توسط تغییر ولتاژ ایجاد می شود)، شدت میدان و نسبت دو گسیل خودبخودی بر رفتار درجه درهمتنیدگی سیستم بررسی شده اشت.با تغییر هر یک از این پارامترها، در...
15 صفحه اولL-WELL-POSEDNESS OF 3D div-curl BOUNDARY VALUE PROBLEMS
Criteria for the existence and uniqueness of weak solutions of div-curl boundary-value problems on bounded regions in space with C-boundaries are developed. The boundary conditions are either given normal component of the field or else given tangential components of the field. Under natural integrability assumptions on the data, finite-energy (L) solutions exist if and only if certain compatibi...
متن کاملFinite Energy Solutions of Mixed 3d Div-curl Systems
This paper describes the existence and representation of certain finite energy (L-) solutions of weighted div-curl systems on bounded 3d regions with C-boundaries and mixed boundary data. Necessary compatibility conditions on the data for the existence of solutions are described. Subject to natural integrability assumptions on the data, it is then shown that there exist L-solutions whenever the...
متن کاملFast and Controllable 3D Modelling From Silhouettes
We show how a 3D model of a complex curved object can be easily extracted from a single 2D image. A userdefined silhouette is the key input; and we show that finding the smoothest 3D surface which projects exactly to this silhouette can be expressed as a quadratic optimization, a result which has not previously appeared in the large literature on the shape-from-silhouette problem. For simple mo...
متن کاملFrame Fields: Anisotropic and Non-Orthogonal Cross Fields Additional material
If we consider the quotient space of each tangent plane with respect to this equivalence relation, and the related quotient tangent bundle TS/∼1, a field FD : S −→ TS/∼1 maps each point on the surface to a direction. It is customary to take unit-length vectors as representatives of their equivalence classes, so that a direction field can be regarded as a vector field where the length of all vec...
