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 ...
Micro-Newton Force Measurement and Actuation : Applied to Genetic Model Organisms
(2018-07-10)
Mechanical forces have been observed to affect various aspects of life, for example, cell differentiation, cell migration, locomotion and behavior of multicellular organisms etc. Such forces are generated either by external ...
Polymer Assisted Dispersion of Carbon Nanotubes (CNTs) and Structure, Electronic Properties of CNT - Polymer Composite
(2018-05-21)
Carbon nanotubes possess various unique and interesting properties. They have very high thermal and electrical conductivities, high stiffness, mechanical strength, and optical properties. Due to these properties, CNTs are ...
Investigations and Stabilization of Vortex States in Cobalt and Permalloy Nanorings in Contact with Nanowires
(2018-07-09)
Magnetic nanorings are the object of increasing scientific interest because they possess the vortex (stray field free) state which ensures lower magnetostatic interactions between adjacent ring elements in high packing ...
Studies of Ultracold Bosons in Optical Lattices using Strong-Coupling Expansions
(2018-06-14)
Cold bosonic atoms trapped in optical lattices formed by standing wave interference patterns of multiple laser beams constitute excellent emulators of models of strongly correlated quantum systems of bosons. In this thesis, ...
Driven Granular and Soft-matter : Fluctuation Relations, Flocking and Oscillatory Sedimentation
(2018-06-11)
Active matter refers to systems driven out of thermal equilibrium by the uptake and dissipation of energy directly at the level of the individual constituents, which then undergo systematic movement in a direction decided ...
Laser Beam Induced Conductance Modulations as a Potential Microprobe in the Investigation of Defects and Inhomogeneities in Bulk Si and PbS, HgCdTe Quantum Dot Heterostructures
(2018-05-18)
In this thesis, the strength of the LBIC system is enhanced in different aspects that includes its feasibility as a non-destructive characterization tool, the signal analysis and development of analytical solution to have ...
Structural, Optical and Electrical Studies on Multi-Functional Organic Single Crystals
(2018-07-09)
In this thesis, the physical properties of certain multi-functional organic crystals were studied in detail. This study involves the growth of single crystals of Glucuronic acidγ-lactone (GAL), Imidazoliumtartarate (IMLT), ...
Topology and Quantum Phases of Low Dimensional Fermionic Systems
(2018-05-21)
In this thesis, we study quantum phase transitions and topological phases in low dimensional fermionic systems. In the first part, we study quantum phase transitions and the nature of currents in one-dimensional systems, ...
