Field theories in nanocommutative spaces
The recent interest in noncommutative spaces has its roots in the study of quantum gravity and string theory. At length scales close to the Planck scale, the usual notion of continuous spacetime is expected to break down ... -
Finite Element Analysis of Interior and Boundary Control Problems
(2018-06-18)The primary goal of this thesis is to study finite element based a priori and a posteriori error estimates of optimal control problems of various kinds governed by linear elliptic PDEs (partial differential equations) of ... -
Finite Element Analysis of Optimal Control Problems Governed by Certain PDEs
The primary goal of this thesis is to study finite element based \textit{a priori} and \textit{a posteriori} error analysis of optimal control problems of various kinds governed by linear elliptic PDEs of second order. ... -
Finite field computational techniques for exact solution of numerical problems
In this dissertation, we consider the application of residue arithmetic for the exact computation of g-inverses in order to obviate the round-off errors normally associated with their computation. It turns out that for ... -
Finite section convolution integral operators structure of resolvent and solution of first kind equations
This thesis investigates the structure of the solutions of Fredholm integral equations of the first and second kinds with convolution kernels on finite intervals and some of its applications. The thesis is divided into ... -
First Principles Study of Oxides : Bulk, Interfaces and Defects
In the recent years, oxides have been the focus of numerous theoretical and experimental studies. This is because of a wide variety of exotic physical phenomenon, such as multiferroicity, charge ordering, metal-insulator ... -
First principles study of the structural, electronic, elastic, mechanical, thermal, and vibrational properties in pyrochlores and temperature-dependent phonon properties in pyrochlores and SrTiO3 perovskite
In this thesis, first-principles density functional theory (DFT) calculations are used to study the structural, electronic, elastic, mechanical, and thermal properties in a series of pyrochlore materials. The vibrational ... -
Flavor and Dark Matter Issues in Supersymmetric Models
(2018-04-06)The Standard Model of particle physics attempts to unify the fundamental forces in the Universe (except gravity). Over the years it has been tested in numerous experiments. While these experimental results strengthen our ... -
Flocks, Flow and Fluctuations in Inanimate Matter : Simulations and Theory
In this thesis we study a novel soft-matter system that imitates motility. Our system consists of a few asymmetrically tapered brass rods and aluminium beads which are confined between two vertically shaking plates. The ... -
Flow in pipes of uniform and non-uniform cross-sections with physiological applications
Laminar flow in pipes and channels with uniform and non-uniform cross-sections plays an important role in many engineering and physiological flow problems. Flow of blood through catheterised and stenosed (constricted) blood ... -
Flow Induced Instabilities, Shear-Thickening And Fluctuation Relations In Sheared Soft Matter
(2016-09-09)In day to day life we encounter many different materials which are intermediate between crystalline solids and simple liquids that include paints , glues , suspensions, polymers, surfactants, food and cosmetic products and ... -
Fluctuation Driven Collective Phenomena in Electron Doped Quantum Paraelectric: KTaO3
The study of quantum phase transitions, in which a system undergoes a change in its ground state and physical properties due to quantum fluctuations at absolute zero temperature, stands as one of the most celebrated themes ... -
Fluctuations in quantum transport in topological insulators
Topological insulators (TIs) belong to a new class of materials characterized by linear surface states, which emerge in the bulk band gap due to non-trivial topology of the band structure. These surface states have various ... -
