Quasi-analytic Functions, Spherical Means, and Uncertainty Principles on Heisenberg Groups and Symmetric Spaces
This thesis has two parts. The first part revolves around certain theorems related to an uncertainty principle and quasi-analyticity. In contrast, the second part reflects a different mathematical theme, focusing on the ... -
Quasicrystals, rational approximants and quasicrystalline tilt boundaries : Theory and experiments
A range of NaBr concentrations (0.02 < X < 0.21) can be examined in an experimentally accessible (Tx - T) range, and there is good temporal stability in Tx also. The cloud point curves for different concentrations of NaBr ... -
A Radio Study Of Gas Loss Processes In Nearby Galaxies
(2008-10-17)The work in this thesis involves detailed multi-frequency radio continuum (from 325 MHz to 15 GHz) and Hi spectroscopic studies of a few represent tative nearby galaxies which are experiencing gas-loss from their disks ... -
Raman and infrared study of vibrational and rotational relaxations
Our data on the area-ratio of the split components of the Ag Raman line in potash alum show a clear departure from the Boltzmann distribution at temperatures below 150 K. Modification of the phonon-induced transition rates ... -
Raman Spectroscopy Instrumentation and Its Application in Deep Tissue Imaging
Raman spectroscopy is based on inelastic scattering, which gives molecular information. Due to its weak nature, for a long-time Raman spectroscopy was limited to only study of molecular interactions, but with the advancement ... -
Raman Spectroscopy Of Graphene And Graphene Analogue MoS2 Transistors
(2016-06-18)The thesis presents experimental studies of device characteristics and vibrational properties of atomic layer thin graphene and molybdenum disulphide (MoS2). We carried out Raman spectroscopic studies on field effect ... -
Raman Studies of Topological Crystalline Insulator, Natural Heterostructures, Excitonic Insulator and Layered Oxide Under Pressure
The theme of this thesis is Raman spectroscopic study of a variety of exotic states of matter under extreme conditions, such as, hydrostatic pressure as high as 25 GPa and a wide temperature range from 77 K to 390 K. Raman ... -
Raman Study of gated devices in two-dimensional materials and pressure effects
This thesis presents Raman study of 2D materials of contemporary interests: 2H-MoTe_2, type-II Weyl semimetal (T_d-MoTe_2), structurally anisotropic semiconductors (1T'-ReX_2 (X=S, Se)) and Mott insulator (FePS_3) under ... -
Randall-Sundrum Model as a Theory of Flavour
(2018-04-11)The discovery of the Higgs boson by the LHC provided the last piece of the puzzle neces- sary for the Standard Model (SM) to be a successful theory of electroweak scale physics. However there exist various phenomenological ... -
Rapid light sheet fluorescence microscopy for dynamic imaging of living organisms
The primary goal of this thesis is to develop a light sheet based microscopy system that provides non-invasive images having high spatial and temporal resolution. The fluorescence microscopy has become an indispensable ... -
Rapid Lightsheet Volume Imaging For Developmental Biology
Optical fluorescence microscopy is one of the key tool, that is indispensable for the study of complex and dynamic biological processes. Key issues associated with the existing fluorescence imaging systems are, ... -

Reactive diffusion in AI/Ge multilayers
It may be mentioned in this context that there is no evidence of the hexagonal and orthorhombic phase reported in e-beam annealed amorphous Al-Ge films in the present investigations. It is also interesting to note that the ... -
Realization of magnetic Weyl semimetallic phase in pyrochlore iridates thin films
Weyl semimetals (WSMs) are characterized by two linear non-degenerate band crossing inside the bulk of the Brillouin zone. The spin-degeneracy of the bands can be lifted by either broken inversion symmetry or broken ... -
Realization of Type-II Dirac Semi-metal in NiTe2 using Structural, Electrical and Magnetic Investigation
Dirac semimetal (DSM) is a topological semi-metal with a fourfold degenerate linear band crossing in the bulk, in the presence of time-reversal symmetry and inversion symme- try, exhibiting nontrivial spin-momentum locking ... -
Recognition of Structures, Functions and Interactions of Proteins of Pathogens : Implications in Drug Discovery
(2018-07-14)Significant advancements in genome sequencing techniques and other high-throughput initiatives have resulted in the availability of complete sequences of genomes of a large number of organisms, which provide an opportunity ...
