This thesis presents some studies on the Loop Quantization of cosmological models. The effect of loop quantization of FRW cosmology in the context of effective equations and WKB approximation are studied in the first ...

One of the most novel concepts in elementary particle physics is that of supersymmetry which ascribes a possible fundamental symmetry between fermions and bosons obeying different statistics. It was an assumption till ...

The thesis is devoted to the study of some problems in Muon Capture, like (i) Gamma Neutrino Angular Correlations; (ii) Recoil Nuclear Polarisation; (iii) Total Capture rates; and (iv) an investigation of (V + A) admixture ...

This thesis aimed to make quantitative analysis of photoproduction of charged pions from nuclei and use it as a probe for studying the photoproduction mechanism, as well as the structure of the nuclei. A detailed study ...

In many cases while interacting many-body systems, the quantum treatment has to be through approximations. One such aspect is semi-classical approximation. These aspects of quantization in the context of simple examples ...

Quantum Chromo Dynamics is accepted as the theory of strong interaction of quarks and gluons. It is a gauge theory with the gauge group as SU(3)C1 the unbroken color group. In this thesis the author examines the ground ...

The Thesis consists of two parts; Part 1 , devoted to Bernstein Problem of Weighted Approximation in the field Approximation theory; Part 2 deals with multiplier transformations associated with weighted spaces. Bernstein ...

The author investigates the nature of quantum Hall states for (sigma)H = 0; (+) or (-) 1, hence the review of the reported experimental works is centered around these states. The quantum Hall experiments for graphene on ...

This review starts with the basic Hilbert space structure for continuous variable systems, explaining the pre-requisites to be able to define a Gaussian state. After that a preliminary study of Gaussian channels is ...

The recent realization of Hofstadter butterfly in moire superlattices and realization of the Hofstadter Hamiltonian in the square lattice in cold atom systems has motivated me to study the effect of interactions in the ...
