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 ...
Deterministic Two Stage Clonal Expansion Model of Breast Cancer Epidemiology and its Utility for Optimal Screening Policies in India
Breast cancer (BC) has emerged as public health issue in India in last two decades sur-passing cervix cancer. Mortality from breast cancer is 30-40% higher than maternal causes. Breast cancer 5 year survival rates are ...
Magnetic and Dielectric Properties of Half Doped RMnO3 (R = Y, Tb)
For the last few decades, the physics of doped perovskite manganite’s (RMnO3) has been an area of intense research due to their interesting physical and electronic properties. Various exciting phenomena such as, colossal ...
Studies of X-Ray Transients and a Future X-Ray Sky Monitor
For this thesis we studied X-ray transients. In addition we also studied some methods to study these transients, both observationally and in terms of the instrument used.
The first transient studied is a black hole binary ...
1H-NMR Study of Proton Glasses - Nuclear Spin Lattice Relaxation in BPxBPI(1-x) and BPxGPI(1-x) - Effects of Disorder on the Proton Group Dynamics
Mixed systems made from a combination of ferroelectric (FE) and antiferroelectric (AFE) compounds, exhibit various effects of disorder in different temperature regions. The kind of effects observed, depend on the technique ...
Geometrical and Topological Properties of CMB Polarization Fields
Cosmic Microwave Background (CMB) is a relic from the early Universe. It was generated due to the physical processes in the early Universe during an epoch known as the recombination or decoupling epoch. The CMB has highly ...
