Low Temperature Charge Transport And Magnetic Properties Of MWNTs/MWNT-Polystyrene Composites
(2014-11-19)Carbon nanotubes (CNTs) have been recognized as potential candidates for mainstream device fabrication and technologies. CNTs have become a topic of interest worldwide due to their unique mechanical and electrical properties. ... -
Magnetisation, Phases & Phase Transitions in Frustrated and Unfrustrated XY Model
(2018-02-23)Through our whole work we study the XY model with all its entirety, a particular spin model where spins are confined in a plane. We try to bring out a good understanding of this model with all different types of phases and ... -
Numerical Study Of The Complex Dynamics Of Sheared Nematogenic Fluids
(2013-07-17)In this thesis, we have tried to explain the regular and irregular(chaotic) dynamics of worm like micellar solutions on applying shear, through a detailed study of the equation of motion of a nematic order parameter tensor ... -
One Dimensional Transport And Prospects Of Structural Transitions In Ultrathin Metallic Wires
(2013-02-25)This thesis reports transport in ultrathin single crystalline nanowires of gold (∼ 2nm). These nanowires were fabricated using an oriented attachment process whereby nanoparticles of appropriate dimensions join in a linear ... -
Optical Tweezers To Probe And Manipulate Soft, Nano And Bio Systems
(2013-01-31)Statistical physics in soft matter systems, physical properties of bio-inspired systems and the mechanical manipulations of nano-systems have been studied using optical tweezers to form the basis of this doctoral Thesis. ... -
Optical, Electrical and Photo-physical Investigations of Cd(Hg)Te Nanostructures Synthesized by Solvothermal Method
The thesis investigates the optical, photo-physical, and electrical properties of CdTe and HgCdTe nano- and micro-structures synthesized by hydrothermal/solvothermal technique. Application oriented studies like fluorescence ... -
Phenomenological Theory Of Superconductivity And Low-Energy Electronic Spectra In The High-Tc Cuprates
(2013-09-11)Condensed matter physics is a rapidly evolving field of research enriched with the synthesis of new materials exhibiting a bewildering variety of phenomena and advances in experimental techniques. Over the years, discoveries ... -
Role Of Surface And Inter-particle Spacing On Optical Properties Of Single And Hybrid Nanoparticle Assemblies
(2013-07-03)Optical properties of nanoscopic materials have been intensively perused over last couple of decades due to their tunable optical properties. Recent interests in this field have been mainly focused on the preparation of ... -
Stability of Accretion Flows And Radiative-Hydrodynamics Around Rotating Black Holes
(2013-06-24)In the case of cold accretion disk, coupling between charge neutral gas and magnetic field is too weak such that the magneto-rotational instability will be less effective or even stop working. In such a situation it is of ... -
Vertical Structure Of Disk Galaxies And Their Dark Matter Halos
(2015-01-02)The topic of this thesis is the study of the vertical structure of the disk galaxies and their dark matter halos through theoretical modeling and numerical calculations. The basic theoretical model of the galactic disk ...
