An experimental study of the specific heat at the glass transition during cooling
In the preceding chapters we have demonstrated the continuous cooling method as a tool for the calorimetric study at the glass transition, bringing out several novel aspects observed in the specific heat measured at the ... -
Analytic and numerical studies of neural network models of associative memory
In this thesis, we have used analytical and numerical methods to study the behaviour of neural network models for the storage, classification and associative recall of information. In Part A, we have studied a class of ... -
Anomalous Translational And Reorientational Dynamics Of Single File Water
(2010-04-12)This thesis deals with several aspects of translational and reorientational dynamics of water molecules confined inside narrow carbon nanotubes. Water molecules confined in a non-polar, nanoscopic pore exhibit extremely ... -
Autonomous Motion, Control Strategies & Sensing Applications Using Magnetic Micro-Robots
In recent years, there has been growing interest in manoeuvring nanoscale objects in fluidic environments, as it holds significant potential in targeted therapies, diagnostics, and probing local rheological properties. ... -
Balloon-borne far infrared observations of galactic star forming regions
Stars are born predominantly within dense cores of giant molecular clouds having number densities > 10? cm?³. This premise is strongly supported by a wealth of observations showing that the hallmarks of newly formed ... -

Bulk and thin growth of pure and substitued indium antimonide for infrared detector applications
InSb single crystals were grown by the vertical and horizontal Bridgman techniques. About 81 experimental runs were carried out altogether (for 8 mm, 10 mm and 20 mm diameter InSb crystals). Among them, as many as 47 runs ... -
The Cahn-Hilliard-Navier-Stokes Framework for Multiphase Fluid Flows: Laminar, Turbulent, and Active
The Cahn-Hilliard-Navier-Stokes (CHNS) framework has found extensive applications, across diverse length and time scales, for multi-phase flows. In this thesis, we demonstrate that this framework offers a robust theoretical ... -
Cahn-Hilliard-Navier-Stokes Investigations of Binary-Fluid Turbulence and Droplet Dynamics
(2017-12-10)The study of finite-sized, deformable droplets adverted by turbulent flows is an active area of research. It spans many streams of sciences and engineering, which include chemical engineering, fluid mechanics, statistical ... -
Carrier Mobility And High Field Transport in Modulation Doped p-Type Ge/Si1-xGex And n-Type Si/Si1-xGex Heterostructures
(Indian Institute of Science, 2007-06-26)Modulation doped heterostructures have revolutionized the operation of field effect devices by increasing the speed of operation. One of the factors that affects the speed of operation of these devices is the mobility of ... -
A cavity electromechanical device for superconducting vortex charge sensing
The penetration of magnetic fields in the form of quantized vortices in type-II superconductors is well known. However, it is not well known that such vortices can be electrically charged. The effect is quite subtle and ... -
Chaos, entanglement, and non-equilibrium dynamics in Hermitian and non-Hermitian quantum many-body systems
Quantum chaos and entanglement have appeared as two key intertwined concepts to characterize fundamental quantum correlations of quantum many-body states and to understand the emergence of thermal and non-thermal steady ... -
Characterization, properties and dynamics of squeezed states: single mode and multimode systems
Squeezed states of the quantized electromagnetic field, as well as the squeezing phenomenon in the more general quantum mechanical context, have been topics of enormous interest recently. In addition to a very large number ... -
Charge Transport And Magnetic Properties Of Iron-embedded Multiwall Carbon Nanotubes
(2014-06-12)Studies on charge transport properties in carbon nanotubes (CNTs) have been a subject of great interest for a long time not only as an important topic in fundamental science, but also as a basic requirement for the application ... -
Charge Transport and Photo-Physical Studies in Conjugated Polymers, Hybrid Nanocomposites and Devices
(2017-12-12)The main motivation of this thesis is derived from the fact that physics of disordered systems like conjugated polymer has yet not achieved as concrete understanding as ordered and crystalline systems such as inorganic ... -
