Higher Spins, Entanglement Entropy And Holography
(2017-08-21)The idea of holography [1, 2] finds a concrete realization in form of the AdS/CFT correspondence [3, 4]. This duality relates a field theory with conformal symmetries to quantum gravity living in one higher dimension. In ... -
Shear Induced Transitions In Mixed Surfactant Systems And Anisotropic Colloids
(2017-06-12)This thesis deals with the non-equilibrium phenomena under shear observed mainly in bilayer forming liquid crystalline phases of mixed surfactant systems, anisotropic colloidal dispersions as well as Langmuir monolayers ... -
Development Of NMR Methods For Metabolomics And Protein Resonance Assignments
(2017-05-25)Nuclear Magnetic Resonance (NMR) spectroscopy is a quantitative, non-invasive and non-destructive technique useful in biological studies. By manipulating the magnetization of nuclei with non-zero spin, NMR gives insights ... -
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 ... -
Structure, Dynamics And Thermodynamics Of Confined Water Molecules
(2017-05-21)This thesis deals with several aspects of the structure and dynamics of water molecules confined in nanoscopic pores. Water molecules confined in hydrophobic nanocavities exhibit unusual structural and dynamic properties. ... -
Electrical Transport And Low Frequency Noise In Graphene And Molybdenum Disulphide
(2017-05-21)This thesis work contains electrical transport and low frequency (1/f) noise measurements in ultrathin graphene and Molybdenum disulphide (MoS2) field effect transistors (FET). From the measurements, We mainly focus on the ... -
Optimization Of NMR Experiments Using Genetic Algorithm : Applications In Quantum Infomation Processing, Design Of Composite Operators And Quantitative Experiments
(2017-05-21)Genetic algorithms (GA) are stochastic global search methods based on the mechanics of natural biological evolution, proposed by John Holland in 1975. Here in this thesis, we have exploited possible utilities of Genetic ... -
Advanced Multifunctional Bulk Optical & Fiber Bragg Grating Sensing Techniques
(2017-05-04)In this thesis work, a systematic quantitative study has been undertaken, on the performance of etched fiber Bragg Grating (FBG) sensors in the investigation of surface molecular adsorption in real-time; it is shown that ... -
Development Of Deterministic And Stochastic Algorithms For Inverse Problems Of Optical Tomography
(2017-04-27)Stable and computationally efficient reconstruction methodologies are developed to solve two important medical imaging problems which use near-infrared (NIR) light as the source of interrogation, namely, diffuse optical ... -
NMR Methods For The Study Of Partially Ordered Systems
(2016-11-16)The work presented in this thesis has two parts. The first part deals with methodological developments in the area of solid-state NMR, relevant to the study of partially ordered systems. Liquid crystals are best examples ... -
Shape Optimization Of A Cylilndrical-Electrode Structure To Mimic The Orbitrap
(2016-11-02)The Orbitrap is a mass analyzer that employs an electrostatic field to confine ions. The mass of an ion is determined from the frequency of its axial oscillations in the Orbitrap. The Orbitrap has high resolving power and ... -
Studies On Direct Sensor Interface Technology For Launch Vehicle Applications
(2016-09-26)In a process monitoring/control applications tens to thousands of sensors are used for monitoring system parameters. To achieve overall system goals, their reliable performance is critical. Generally a sensor’s output ... -
Phases, Transitions, Patterns, And Excitations In Generalized Bose-Hubbard Models
(2016-09-12)This thesis covers most of my work in the field of ultracold atoms loaded in optical lattices. This thesis can be divided into five different parts. In Chapter 1, after a brief introduction to the field of optical lattices ... -
