Cosmic Microwave Background Anisotropies Induced by Global Scalar Fields: The Large N Limit
We present an analysis of CMB anisotropies induced by global scalar fields in the large N limit. In this limit, the CMB anisotropy spectrum can be determined without cumbersome 3D simulations. We determine the source functions and their unequal time correlation functions and show that they are quite similar to the corresponding functions in the texture model. This leads us to the conclusion tha...

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 اولThe scalar, vector and tensor contributions of a stochastic background of magnetic fields to CMB anisotropies
We study the contribution of a stochastic background (SB) of primordial magnetic fields (PMF) on the anisotropies in temperature and polarization of the cosmic microwave background radiation (CMB). A SB of PMF modelled as a fully inhomogeneous component induces non-gaussian scalar, vector and tensor metric linear perturbations. We give the exact expressions for the Fourier spectra of the releva...
متن کاملRecent Developments in the Calculation of Cmb Anisotropies
We discuss three recent developments in the calculation of Cosmic Microwave Background (CMB) anisotropies. We begin with a discussion of the relativistic corrections to the Sunyaev-Zel’dovich effect. By extending the Kompaneets equation to include relativistic effects, we are able to to derive simple analytic forms for the spectral changes due to the thermal Sunyaev-Zel’dovich effect. Relativis...
متن کاملPrimordial magnetic fields and CMB anisotropies
Possible signatures of primordial magnetic fields on the Cosmic Microwave Background (CMB) temperature and polarization anisotropies are reviewed. The signals that could be searched for include excess temperature anisotropies particularly at small angular scales below the Silk damping scale, B-mode polarization, and non-Gaussian statistics. A field at a few nG level produces temperature anisotr...
