Study of Stellar Relics from the Early Galaxy
The thesis, in general aims at studying the early history of the Milky way through the chemical abundances of metal poor stars in the Halo and in the satellite galaxies of the Milky way. Halo of a galaxy is one of the early ...
AGN Feedback in Galaxy Clisters - Controlling Cooling Flows in Galaxy Clusters by Momentum-driven AGN Jets
Synopsis
According to the hierarchical structure formation model, massive structures like galaxy clusters are formed due to the gravitational collapse of initial density perturbations and their subsequent mergers. ...
Topological Insulators and Transition Metal Dichalcogenides Under Extreme Conditions : Optical Studies
This thesis presents experimental as well as theoretical studies of three dimensional topological in-sulators (TIs) and transition metal dichalcogenides (TMDs). Raman spectroscopic measurements of these systems have been ...
Emergent Phenomena from Contacts and Disorder in High Mobility Graphene
The discovery of graphene and analogous van der Waals materials offers a platform for the discovery and exploration of various novel physical phenomena. Here we study the effects of local interaction and strong localisation ...
Iridates, Black Phosphorus, Weyl and Dirac Semimetals Under Extreme Conditions : Raman Study
This thesis presents Raman studies of Sodium iridates (Na2IrO3 and Na4Ir3O8), VO2, black phosphorus, Weyl (TaAs, TaP, NbP and NbAs) and Dirac (Cd3As2) semimetals under ex-treme conditions like low temperature (upto 4K), ...
Fermi Bubbles and Galactic Outflows in Circumgalactic Medium
Galactic outflows play an important role in the formation and evolution of galaxies by regulating the star formation rate (SFR) within them and by throwing out metals into the intergalactic medium (IGM). They are key to ...
Study of Photo-generated Charge Transport in Graphene-based Hybrid Structures
Hybrid structures involving atomic/molecular membranes from two or more layered materials
are emerging as a platform for novel class of field effect transistors (FETs), p - n
junctions, photo-detectors, photo-voltaic ...
Glassy Dynamics in Active Matter
There has been much interest in the glassy dynamics of living systems at the scales
of subcellular structures, cells and tissues. This has motivated theoretical studies on
the approach to glassy behaviour in dense systems ...
Probing the Nature of Dark Matter in the Universe
The dark matter is the most dominating matter candidate and a key driving force for the structure
formation in the universe. Despite decade-long searches, the precise nature and particle
properties of dark matter are ...
Flocks, Flow and Fluctuations in Inanimate Matter : Simulations and Theory
In this thesis we study a novel soft-matter system that imitates motility. Our system consists of a few asymmetrically tapered brass rods and aluminium beads which are confined between two vertically shaking plates. The ...
