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 اولSingularities in the optical response of cuprates
We argue that the detailed analysis of the optical response in cuprate superconductors allows one to verify the magnetic scenario of superconductivity in cuprates. As for strong coupling charge carriers to antiferromagnetic spin fluctuations, the second derivative of optical conductivity should contain detectable singularities at 2D1Dspin , 4D , and 2D12Dspin , where D is the amplitude of the s...
متن کاملRings of Singularities
This paper is a slightly revised version of an introduction into singularity theory corresponding to a series of lectures given at the ``Advanced School and Conference on homological and geometrical methods in representation theory'' at the International Centre for Theoretical Physics (ICTP), Miramare - Trieste, Italy, 11-29 January 2010. We show how to associate to a triple of posit...
متن کاملThe plurality of subcortical infarction.
The designation of the term "subcortical infarction" has often been equated with the diagnosis of lacunar infarction. This identity is incorrect and misleading. Lacunes were reported by French authors in the 19th and early 20th centuries; they were considered to correspond to small (usually <1 cm diameter) cavities in the deep cerebral hemispheres parenchyma, resulting from three distinct proce...
متن کاملThe Plurality of Melodic Similarity
Melodic similarity is a much-researched topic. While there are some common paradigms and methods, there is no single emerging model. The different means by which melodic similarity has been studied are briefly surveyed and contrasts drawn between them which lead to important differences in the light of the finding that similarity is dependent on context. Models of melodic similarity based on re...
