Electric, Magnetic and Magnetocaloric Studies of Magnetoelectric GdMnO3 and Gd0.5Sr0.5MnO3 Single Crystals
(2018-05-10)
After the prediction of magnetoelectric effect in Cr2O3, in early 1960's, D. Asrov became the first to experimentally verify this phenomenon. After the pioneering work on magnetoelectric materials in 1960's and 1970's, the ...
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 ...
Precision Measurements of the Radio Background at Long Wavelengths
(2018-05-09)
The study of continuum sky background spectrum at low radio frequencies has achieved specific importance in present day observational cosmology . At these low frequencies the sky continuum is contributed by the extragalactic ...
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, ...
Quantum Algorithms Using Nuclear Magnetic Resonance Quantum Information Processor
(2009-05-12)
The present work, briefly described below, consists of implementation of several quantum algorithms in an NMR Quantum Information Processor.
Game theory gives us mathematical tools to analyze situations of conflict between ...
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 ...
Magnetic Ordering in Bulk and Nanoparticles of Certain Bismuth Based Manganites Bi1-xAxMnO3 (A = Ca, Sr) : Electron Paramagnetic Resonance and Magnetization Studies
(2018-05-07)
The study of bulk and nanoparticles of perovskite rare earth manganites has been an extensive area of research in the recent past due to their rich and interesting physics and potential applications [1-5]. Manganites have ...
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, ...
Elasticity And Structural Phase Transitions Of Nanoscale Objects
(2015-12-14)
Elastic properties of carbon nanotubes (CNT), boron nitride nanotubes (BNNT), double stranded DNA (dsDNA), paranemic-juxtapose crossover (PX-JX) DNA and dendrimer bound DNA are discussed in this thesis. Structural phase ...
