Dynamics, Order And Fluctuations In Active Nematics : Numerical And Theoretical Studies
(2010-08-24)In this thesis we studied theoretically and numerically dynamics, order and fluctuations in two dimensional active matter with specific reference to the nematic phase in collections of self-driven particles.The aim is to ... -
Dynamo Action in Rotating and Shearing Flows
Magnetic fields are omnipresent in universe. They play important role in the formation of stars, galaxies and the accretion onto compact objects and the collimation of the relativistic jets of radio galaxies. It is intriguing ... -
ECR Assisted Deposition of Tin And Si3N4 Thin Films For Microelectronic Applications
(Indian Institute of Science, 2006-02-27)The broad theme of the present research investigation is Ion Assisted Deposition of thin films and its effect on the properties of thin films. Though this activity has been of interest to researchers for more than a decade, ... -
ECR Plasma Deposition Of Carbon - Studies On DLC Coatings And Carbon Nanotubes
(2010-10-13)Recent developments in the field of nano-structured materials for technological as well as scientific prospective are quite interesting. In this context carbon plays a dominant role. Few examples such as carbon nanotubes ... -
ECR Studies Across Bare And Gold Coated Metal Contacts At Low Temperatures
(2011-01-28)Electrical contact resistance (ECR) measurements are needed for judging the performance of electrical appliances. Understanding the behaviour of ECR at low temperature gives a unique opportunity for understanding the contact ... -
Edge States and Effects of Disorder in Finite Graphene Sheets
The thesis endeavours to theoretically understand electronic properties of nite trapezoidal shaped graphene sheets, and understand zero energy edge states. The motivation for this thesis is recent experimental work at Low ... -
Edible Battery Design for Bio-Medical applications
This thesis is focused on the development of digestible electronics for healthcare. The vision is the development of an edible pill that performs diagnosis inside the body. Any such edible device needs an energy source ... -
Effect of a fast flux line on the coherence of 3D transmon qubits
With the development of the science and technology, the quantum computers are becoming the possible key to reveal new breakthroughs. Unlike the classical computers, where we have classical bits (0or1), in quantum computation ... -
Effect of a QSO on its host galaxy
Various arguments and observations have led to a general belief that QSO phenomenon is a form of violent activity in the nuclei of galaxies. It is natural to expect that a powerful source of high energy radiation like a ... -
Effect of AGN on the ISM of their hosts: A multi-wavelength perspective
Active Galactic Nuclei (AGN) are among the high luminosity (1011 − 1014 L⊙ ) sources in the observable Universe, believed to be powered by the accretion of matter onto supermassive black holes (SMBHs; 105 − 1010 M⊙ ) at ... -
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 ... -
Effect of As and Se substitution on the Phase Change properties of GeTe based alloys
Phase-change memory (PCM) is a key enabling technology for non-volatile electrical data storage at the nanometer scale. A PCM device consists of a small active volume of phase-change material between two electrodes. In ... -
Effect of external highfrequency fields on unbounded and bounded plasmas
It is widely recognised that the plasmas either in nature or in laboratory are bounded in one way or the other. In many situations, these plasmas are subjected to external oscillating fields such as laser?produced plasma ... -
Effects of disorder on interacting fermionic systems in one dimension
The work begins with constructing an XXX matrix whose diagonal elements represent the momenta of a classical NNN-particle system, while off-diagonal elements are odd functions of coordinates. Summing over rows of this ... -
