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 ... -
Flow Induced Instabilities, Shear-Thickening And Fluctuation Relations In Sheared Soft Matter
(2016-09-09)In day to day life we encounter many different materials which are intermediate between crystalline solids and simple liquids that include paints , glues , suspensions, polymers, surfactants, food and cosmetic products and ... -
Fluctuation Driven Collective Phenomena in Electron Doped Quantum Paraelectric: KTaO3
The study of quantum phase transitions, in which a system undergoes a change in its ground state and physical properties due to quantum fluctuations at absolute zero temperature, stands as one of the most celebrated themes ... -
Fluctuations in quantum transport in topological insulators
Topological insulators (TIs) belong to a new class of materials characterized by linear surface states, which emerge in the bulk band gap due to non-trivial topology of the band structure. These surface states have various ... -
Fluid Flow And Electrochemical Bias Induced Effects In Carbon Nanotubes And Raman Studies On Iron Perovskites
(2011-09-30)This thesis is divided into two parts; the first part presents results on the effect of the flow of fluids and electrochemical bias on single walled carbon nanotubes (SWNT). Issues pertaining to the entry of water into the ... -
Fully Solution Processed Flash Memory
The field of advanced solution processed spin-coated electronics has rapidly expanded over the last few decades towards the development of low-cost, large area and low power consumer electronics for the design of ... -
Fundamental aspects of the interface engineering in the heavy metal/ferromagnet-based perpendicularly magnetized systems
The ferromagnetic (FM) material finds its applications due to the property of spontaneous magnetization. An FM object can hold its state of magnetization unless any external stimuli change it. The easy manipulation of its ... -
Generalizations Of The Quantum Search Algorithm
(2010-12-03)Quantum computation has attracted a great deal of attention from the scientific community in recent years. By using the quantum mechanical phenomena of superposition and entanglement, a quantum computer can solve certain ... -
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 ... -
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 ... -
Global gyrokinetic simulations of electrostatic microturbulent transport in LHD stellarator and ADITYA-U tokamak
Tokamak and stellarator are two leading contenders in the quest to achieve nuclear fusion from magnetically-confined plasmas. They differ in terms of magnetic field structure in the toroidal direction. Irrespective of the ... -
Graphene And Carbon Nanotubes : Field Induced Doping, Interaction With Nucleobases, Confined Water And Sensors
(2010-12-08)This thesis presents experimental and related theoretical studies of single layer graphene, bilayer graphene and single walled carbon nanotubes. The thesis is divided into three parts; the first part describes the phonon ... -
Gravitational Waves From Inspiralling Compact Binaries : 3PN Polarisations, Angular Momentum Flux And Applications To Astrophysics And Cosmology
(2010-09-03)Binary systems comprising of compact objects like neutron stars (NS) and/or black holes (BH) lose their energy and angular momentum via gravitational waves (GW). Radiation reaction due to the emission of GW results in a ... -
Growth And Characterization Of Technologically Important Nonlinear Optical Crystals: Cesium Lithium Borate And Potassium Di-Deuterium Phosphate
(2008-09-30)Present day advanced technologies heavily rely on one particular class of matter, i.e. the crystals. It is the periodic nature of the atoms and the properties arising due to the periodicity in crystals that is exploited ... -
