#### Study of Optical Properties of Semiconductor Quantum Dot Based Hybrid Nano Assemblies

(2017-11-28)

Over the last few decades, a vast research is going on, to study the optical properties of the nano particles i.e., metal and semiconductors thoroughly. Till date most of the optical studies are based on single particle ...

#### Numerical Studies of Problems in Turbulence : 1) Fluid Films with Polymer Additives; 2) Fluid Films with Inertial and Elliptical Particles; 3) Scaled Vorticity Moments in Three- and Two-dimensional Turbulence

(2017-11-30)

In this thesis we study a variety of problems in fluid turbulence, principally in two dimensions. A summary of the main results of our studies is given below; we indicate the Chapters in which we present these.
In Chapter ...

#### 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 ...

#### Direct Measurement of Itinerant Magnetism & Interface States in Semiconductors using Time-varying Magnetic Fields

(2017-11-28)

Magnetism in a solid | dia, para, ferro, or of other forms | originates majorly from its electrons; one could, infact, ignore the nuclear contribution. There are two types of electrons in a solid: bound, and free (also ...

#### Quantum Simulations by NMR : Applications to Small Spin Chains and Ising Spin Systems

(2017-11-22)

Quantum simulations, where controllable quantum systems are used to simulate other quantum systems, originally proposed by Richard Feynman, are one of the most remarkable applications of quantum information science. Compared ...

#### Mixed Alkali Effect in Oxyfluoro Vanadate Glasses And The Effect of Rare Earth Ions on Oxyfluoro Tellurite Glasses - A Spectroscopic Study

(2017-09-20)

The main motivation of this thesis is to study the long standing problem of mixed alkali effect (MAE) in oxyfluro vanadate glass systems from the point of view of structural arrangement and to investigate the effect of two ...

#### Continuous Beam of Laser-Cooled Ytterbium Atoms for Precision Measurements

(2017-11-22)

What if an elementary particle such as an electron had an intrinsic electric dipole moment (EDM)? Existence of such an EDM would be an indication of time-reversal symmetry
violation in the laws of Physics. The Standard ...

#### Study of Phase Transitions in Two Dimensions using Electrical Noise

(2017-11-21)

It is well known from Mermin-Wagner theorem that a two dimensional(2D) system with continuous symmetry can have no long-range order at finite temperature. However such systems can undergo a transition from a low temperature ...

#### Study of Light-Matter Interaction at the Nanoscale with Quantum Dots in Photonic and Plasmonic Metamaterials

(2017-11-28)

Optical properties of nanoscopic materials have been intensively pursued over last couple of decades due to their tunable optical properties. Recent interests in this field have been mainly focused on the preparation of ...

#### Optical, AC Conductivity, NMR and Raman Studies of Alkali Borogermanate Glasses

(2017-11-22)

Physical properties of materials and their constituents are interrelated. Though the
basic structural unit involved also plays a role in deciding the properties, this can be
manipulated to a certain extent, by carefully ...
