Investigating Systematics In The Cosmological Data And Possible Departures From Cosmological Principle
(2013-06-11)
This thesis contributes to the field of dark energy and observational cosmology. We have investigated possible direction dependent systematic signal and non-Gaussian features in the supernovae (SNe) Type Ia data. To detect ...
Stability of Accretion Flows And Radiative-Hydrodynamics Around Rotating Black Holes
(2013-06-24)
In the case of cold accretion disk, coupling between charge neutral gas and magnetic field is too weak such that the magneto-rotational instability will be less effective or even stop working. In such a situation it is of ...
Insights into Substrate Specificity in Sortase Enzymes from Structural Studies on a Novel Class of Housekeeping Sortase (SrtE) Identifying Functionally Important Cis-Peptide Containing Segments in Proteins and their utility in Molecular Function Annotation
(2018-02-21)
Understanding protein function is fundamental to the fields of protein engineering and drug design. While most of the previous efforts in this direction have focused on the sequence-structure-function paradigm, recent ...
A Study of Superbubbles in the ISM : Break-Out, Escape of LYC Photons and Molecule Formation
(2018-02-16)
Multiple coherent supernova explosions (SNe) in an OB association can produce a strong shock that moves through the interstellar medium (ISM). These shocks fronts carve out hot and tenuous regions in the ISM known as ...
Impact of Disorder and Topology in Two Dimensional Systems at Low Carrier Densities
(2018-02-15)
Two dimensional (2D) systems with low carrier density is an outstanding platform for studying a wide spectrum of physics. These include both classical and quantum effects, arising from disorder, Coulomb interactions and ...
Engineering Plasmonic Interactions in Three Dimensional Nanostructured Systems
(2018-02-08)
Strong light matter interactions in metallic nanoparticles (NPs), especially those made of noble metals such as Gold and Silver is at the heart of much ongoing research in nanoplasmonics. Individual NPs can support collective ...
Exchange Spring Behaviour in Magnetic Oxides
(2018-02-23)
When a permanent magnet is considered for an application, the quantity that quantifies the usability of that material is the magnetic energy product (BH)max. In today’s world, rare earth transition metal permanent magnets ...
Charge Transport in Semiconducting Polymer Devices
(2018-02-23)
Understanding the fundamentals of Organic semiconductors is crucial aspect towards the technological applications. Conjugated polymers have shown many interesting physical properties. Especially the electronic and optical ...
Hyperfine Structure-Measurement in Alkali-metal Atoms and Ytterbium Atom
(2018-02-15)
Atomic precision measurements provide a strong testing ground for new theoretical ideas and fundamental laws of physics. Measurement of the Lamb shift in the hydrogen atom is one of the best examples towards this -it ...
Magnetisation, Phases & Phase Transitions in Frustrated and Unfrustrated XY Model
(2018-02-23)
Through our whole work we study the XY model with all its entirety, a particular spin model where spins are confined in a plane. We try to bring out a good understanding of this model with all different types of phases and ...
