Studies Of Electronic, Magnetic And Entanglement Properties Of Correlated Models In Low-Dimensional Systems
(2015-09-04)This thesis consists of six chapters. The first chapter gives an introduction to the field of low-dimensional magnetic and electronic systems and relevant numerical techniques. The recent developments in molecular magnets ... -
Studies of Feynman and Related Integrals and their Hypergeometric Connection using the Method of Brackets, Algebraic Relations and Singularity Analysis
Feynman integrals are special kind of integrals that arise in perturbative quantum field theory and are often very difficult to evaluate in terms of known functions of mathematical physics. At times some of the methods ... -
Studies Of Phosphorus-Functionalized Calix[4]arenes And Their Palladium Complexes
(2009-03-31)Calixarenes, particularly calix[4]arenes, continue to attract considerable attention in synthetic chemistry, notably as platforms for designing sophisticated molecular cages and claw-like ligands. Incorporation of phosphorus ... -
Studies Of Spiral Turbulence And Its Control In Models Of Cardiac Tissue
(2010-07-15)There is a growing consensus that life-threatening cardiac arrhythmias like ventricular tachycardia (VT) or ventricular fibrillation (VF) arise because of the formation of spiral waves of electrical activation in cardiac ... -
Studies of Static and Dynamic Multiscaling in Turbulence
(Indian Institute of Science, 2005-06-17)The physics of turbulence is the study of the chaotic and irregular behaviour in driven fluids. It is ubiquitous in cosmic, terrestrial and laboratory environments. To describe the properties of a simple incompressible ... -
Studies of Topological Phases of Matter : Presence of Boundary Modes and their Role in Electrical Transport
(2018-05-21)Topological phases of matter represent a new phase which cannot be understood in terms of Landau’s theory of symmetry breaking and are characterized by non-local topological properties emerging from purely local (microscopic) ... -
Studies of Ultracold Bosons in Optical Lattices using Strong-Coupling Expansions
(2018-06-14)Cold bosonic atoms trapped in optical lattices formed by standing wave interference patterns of multiple laser beams constitute excellent emulators of models of strongly correlated quantum systems of bosons. In this thesis, ... -
Studies of X-Ray Transients and a Future X-Ray Sky Monitor
For this thesis we studied X-ray transients. In addition we also studied some methods to study these transients, both observationally and in terms of the instrument used. The first transient studied is a black hole binary ... -
Studies On AC Losses In Certain Type II Superconductors
(2010-06-14)Studies on ac losses in superconductors have been a subject of great interest for a long time not only as an important topic in fundamental science, but also as a basic requirement for the application of superconductors. ... -
Studies on AgInS2 Films as Absorber Layer for Heterojunction Solar Cells
(2017-11-28)Currently conventional sources like coal, petroleum and natural gas meet the energy requirements of developing and undeveloped countries. Over a period of time there is high risk of these energy sources getting depleted. ... -
Studies On Atmospheric Glow Discharge For Surface Modification Applications
(2010-10-22)The properties of materials, especially of solids, can be attributed mainly to the phenomena occurring at the surface. Surface engineering deals with altering the surface properties of materials to realize useful functionalities ... -
