Direct Numerical Simulations of Fluid Turbulence : (A) Statistical Properties of Tracer And Inertial Particles (B) Cauchy-Lagrange Studies of The Three Dimensional Euler Equation
(2017-11-09)
The studies of particles advected by tubulent flows is an active area of research
across many streams of sciences and engineering, which include astrophysics,
fluid mechanics, statistical physics, nonlinear dynamics, and ...
Direct Measurement of Itinerant Magnetism & Interface States in Semiconductors using Time-varying Magnetic Fields
(2017-11-28)
Magnetism in a solid | dia, para, ferro, or of other forms | originates majorly from its electrons; one could, infact, ignore the nuclear contribution. There are two types of electrons in a solid: bound, and free (also ...
Experimental Investigation of Multielectron Bubbles in Liquid Helium
(2017-11-28)
Multielectron bubbles (MEBs) are micron sized cavities in liquid helium that contain electrons confined within a nanometer thick layer on the inner surface of a bubble. These objects present a rich platform to study the ...
Optical, AC Conductivity, NMR and Raman Studies of Alkali Borogermanate Glasses
(2017-11-22)
Physical properties of materials and their constituents are interrelated. Though the
basic structural unit involved also plays a role in deciding the properties, this can be
manipulated to a certain extent, by carefully ...
Effect of Antimony Doping in Iron Chalcogenides
(2017-11-27)
This thesis is organized in to six chapters. The contents of each chapter are briefly summarized in the following sections.
Chapter 1 introduces different Fe-based superconductors. Within a very short span of their ...
Collective Behaviour of Confined Equilibrium And Non Equilibrium Soft Matter Systems
(2017-11-09)
Due to their diversity, soft matter systems provide a convenient platform to study a variety of physical phenomena like phase transitions and collective motion. Encompassing a wide range of equilibrium and non-equilibrium ...
Structure, Dynamics And Thermodynamics Of Confined Water Molecules
(2017-05-21)
This thesis deals with several aspects of the structure and dynamics of water molecules confined in nanoscopic pores. Water molecules confined in hydrophobic nanocavities exhibit unusual structural and dynamic properties. ...
Optimization Of NMR Experiments Using Genetic Algorithm : Applications In Quantum Infomation Processing, Design Of Composite Operators And Quantitative Experiments
(2017-05-21)
Genetic algorithms (GA) are stochastic global search methods based on the
mechanics of natural biological evolution, proposed by John Holland in 1975. Here
in this thesis, we have exploited possible utilities of Genetic ...
The Cosmic Population of Extended Radio Sources : A Radio-Optical Study
(2017-09-27)
This thesis presents studies of cosmic populations of extragalactic radio sources. The problems selected for this thesis are 1) the derivation of constraints on the emergence of new sub-mJy populations at flux density below ...
Study of Optical Properties of Semiconductor Quantum Dot Based Hybrid Nano Assemblies
(2017-11-28)
Over the last few decades, a vast research is going on, to study the optical properties of the nano particles i.e., metal and semiconductors thoroughly. Till date most of the optical studies are based on single particle ...
