Some Unconventional Phases And Phase Transitions In Condensed Matter : Spin-Nematics, Spin-Liquids, Deconfined Critical Points And Graphene NIS Junctions
(2013-07-19)Condensed matter physics provides us with an opportunity to explore a large variety of systems with diverse properties. Central to the understanding of these systems is a characterization of the nature of their ground ... -
The Space of Metric Measure Spaces
(2018-05-22)This thesis is broadly divided in two parts. In the first part we give a survey of various distances between metric spaces, namely the uniform distance, Lipschitz distance, Hausdor distance and the Gramoz Hausdor distance. ... -
Sparse bounds for various spherical maximal functions
Harmonic analysis mainly deals with the qualitative and quantitative properties of functions and transforms of those functions. It has applications in various areas of Mathematics like PDE, Differential geometry, Ergodic ... -
Spatial Encoding NMR : Methods and Application to Relaxation Measurements, Dissolution Monitoring and Ultrafast NMR
(2018-02-06)Discrete and Continuous spatial encoding methods are described with details of understanding principles and practical implications. Step by step experimental op- timization procedure of these methods to achieve slice ... -
Spatial Filtering Techniques for Large Penetration Depth and Volume Imaging in Fluorescence Microscopy
(2018-04-06)In the past two decades, Fluorescence microscopy has imparted tremendous impact in Biology and Imaging. Several super-resolution Fluorescence imaging techniques (e.g. PALM, STED, STORM, 4Pi and structured illumination) ... -
Spatially Resolved Studies Of Electronic Phase Separation And Microstructure Effects In Hole Dopped Manganites
(2010-08-17)The main focus of this thesis is in understanding the role of phase separation and microstructure in determining the physical properties of manganites. We also aim to be able to tune certain material properties using ... -
Spectral And Transport Properties Of Falicov-Kimball Related Models And Their Application To Manganites
(2010-03-26)From the time of the unexpected discovery of the insulating nature of NiO by Verwey half a century ago, Oxide materials have continued to occupy the centre stage of condensed matter physics. The recent discovery of high ... -
Spectral Theory And Root Bases Associated With Multiparameter Eigenvalue Problems
(2010-06-01)Consider (1) -yn1+ q1y1 = (λr11 + µr12)y1 on [0, 1] y’1(0) = cot α1 and = y’1(1) = a1λ + b1 y1(0) y1(1) ... -
Spectro-temporal signatures of accretion flows around Galactic Black Holes
A system of two stars in which one is a black hole (BH) is referred to as a black hole binary (BHB). In a BHB, it is possible to have mass transfer from the secondary star (companion star) to the primary black hole. ... -
Spectroscopic and Diffraction Signatures of Quantum Spin Liquids, Skyrmion Lattices and Transition Metal Dichalcogenides at Low Temperatures and High Pressures
This thesis presents experimental as well as theoretical studies on several contemporary systems like quantum spin liquids (QSLs), skyrmion lattices, and transition metal dichalcogenides (TMDs) under extreme conditions ... -
Spectroscopic study of emitter assemblies coupled to Plasmonic nano-cavities and metamaterials
The plasma oscillations of noble metals as silver and gold are well understood from the free electron model of metals. In the past two decades, due to the availability of various physical and chemical fabrication methods ... -
Spin Hall Effect Mediated Current Induced Magnetization Reversal in Perpendicularly Magnetized Pt/Co/Pt Based Systems
(2018-02-08)In the present thesis, magnetization reversal in both out-of-plane and in-plane magnetized thin lms and in devices fabricated out of those lms are explored. Pt/Co/Pt stacks with ultrathin Co layer were in-estimated initially ... -
Spiral- And Scroll- Wave Dynamics In Ironically And Anatomically Realistic Mathematical Models For Mammalian Ventricular Tissue
(2017-05-24)Cardiac arrhythmias, such as ventricular tachycardia (VT) and ventricular fibrillation (VF), are among the leading causes of death in the industrialized world. There is growing consensus that these arrhythmias are associated ... -
Spiral-Wave Dynamics in Ionically Realistic Mathematical Models for Human Ventricular Tissue
(2018-04-18)There is a growing consensus that life-threatening cardiac arrhythmias like ven- tricular tachycardia (VT) or ventricular fibrillation (VF) arise because of the formation of spiral waves of electrical activation in cardiac ... -
