Mott-Hubbard Phenomena : Studies Within The Local Approximation
(2012-01-10)In this thesis we address a few such problems involving the microscopic theory of strongly correlated electrons using the d-tca or local approximation. The rest of this Chapter is organised as follows: we summarise the ... -
Multi-Dimensional Solid State NMR - Methods Development and Application to Materials
In recent years, the scope of application of solid-state NMR to different areas has been witnessing a significant increase. Primarily, this is due to the possibility of routine use of proton NMR spectroscopy at ultrafast ... -
Multi-Nuclear and Multiple-Quantum NMR in the Solid-State : Methods and Applications
(2018-01-03)NMR spectroscopy is a very powerful technique for the characterization of structure and dynamics of a variety of systems starting from small organic molecules to large biological macromolecules. In solids, the study of ... -
Multiband Modelling and Radio Observations of Gamma Ray Burst Afterglows
The widely popular and successful standard fireball model for Gamma Ray Burst (GRB) afterglows is based on ultra-relativistic external shocks sweeping up matter around the explosion site to accelerate electrons up to GOV ... -
Multicarrier Effects In High Pulsed Magnetic Field Transport And Optical Properties Of Mercury Cadmium Telluride
(2011-01-17)This thesis on multicarrier effects in the magnetotransport and optical properties of Mercury Cadmium Telluride (MCT or HgCdTe) covers mainly: design, construction and calibration of a 12T 4K and 19T 77K pulsed high magnetic ... -
Multiphase gas in the baryon cycle: from jellyfish galaxies to turbulent galactic outflows
The formation and evolution of galaxies are shaped not only by gravity but also by the complex behaviour of gas—the dominant baryonic component within and around galaxies. This gas spans a wide range of temperatures, ... -
Multiple Stable States and Abrupt Transitions in Spatial Ecosystems
Ecosystems can exhibit multiple stable states at similar external conditions. Such systems shift from one stable state to another abruptly and discontinuously, when they cross certain threshold parameters. Some examples ... -
Multiscale Modeling of Molecular Sieve Membranes
Gases permeating through nanopores experience selective adsorption with sub-diffusive dynamics. In this work we investigate how the physicochemical properties of nanoporous membranes influence adsorption dynamics of gases, ... -
Multiscale Simulation of Nucleic Acid Nanostructures
Nucleic acids, namely DNA and RNA, are arguably the most studied biological molecules. Utilizing the key properties of nucleic acids, such as their persistence lengths and Watson-Crick base-pairing complementarity, ... -
Multiscaling in three-dimensional fluid turbulence
Fluid turbulence remains one of the most fascinating unsolved problems in Physics. Different aspects of it have attracted physicists and fluid dynamicists for decades. This thesis studies multiscaling of velocity structure ... -
Nanodevices of Graphene, Carbon Nanotubes and Flow Behaviour of Graphene Oxide Gel
(2018-05-09)In the last three decades carbon nanomaterials such as fullerenes, carbon nanotubes and graphene have attracted significant attention from the scientific community due to their unique electronic, optical, thermal, mechanical ... -
Nanoscale spatial and temporal response of lipid membranes interacting with biomolecules and nanoparticles
The cell membrane is the first point of interaction whenever any external biomolecule or nanoparticle encounters a cell. Thus the nature of interactions between the cell membrane and various proteins, nanoparticles, and ... -
