The thesis presents the modelling and simulation of free running semiconductor laser. The rate equations which were derived on the basis of the fact that there must be a balance between carriers that undergo transition ...

A popular model that have been used to study ferromagnetism is the Ising Model which is an arrangement of spins along a particular direction and with discrete values of + 1 . 1-D Ising model doesn't show a phase transition ...

The ratchet effect is the rectified motion of atoms using an unbiased driving force. By ‘’unbiased’’ we mean to say that the time-average is equal to zero. This can be accomplished experimentally using cold atoms in a ...

The basic understanding of the underlying techniques of growing Carbon Nanotubes (CNTs) with a specific chirality is still obscure and needs to be understood so as to properly harness its potentials. Using both Classical ...

The use of High Intensity Focused Ultrasound (HIFU) in the medical treatment of cancer has attracted scientists and engineers with interest in achieving the most financially affordable but yet curative methods of curing ...

Active polar gels are a type of viscoelastic soft material formed by polar filaments which are constantly driven out of equilibrium by the consumption of chemical fuel such as ATP. Following the approach of Voituriez et ...

In this research work, we study and analyse Hindmarsh-Rose neuronal system with time delay. Considering the fast sub-system of the model, all the possible non-negative equilibria are obtained and their local as well as ...

Key to Escherichia coli (E-coli) bacteria survival is its ability to direct its movement to greener pasture and flee harmful environment - also known as chemotaxis. This thesis focuses on the modelling of E-coli chemotaxis ...

Despite the excellent properties of graphene, graphene based electronic devices are yet to be realized, one of the reason for such is the absence of band gap in graphene. Due to its large band gap, hexagonal boron nitride ...

The development of inexpensive, non-toxic, high efficiency and earth-abundant solar absorbers is critical for terawatt scale implementation of photovoltaics. Cu 2 SnS 3 is a promising earth abundant absorber material that ...

This thesis presented the surface modification of polydimethyl siloxane (PDMS) to enhance surface wettability and surface roughness. Physical and chemical modifications were performed on cured surfaces of PDMS and PDMS-based ...

The high temperature superconducting cuprates show some non Fermi liquid behaviour in their normal state. Also there is no generally accepted theory of high temperature superconductivity. The BCS theory has failed to ...

The advent of nanotechnology together with Biomedical Microelectro-Mechanical Systems (BioMEMS) for improved efficacy in treatment of cancer has resulted in the development of an implantable biomedical device for localized ...

The study explores the potential effects of the remote application of cyclic magnetic field to the female anopheles mosquitoes that carry malaria parasites. The goal is to develop a theoretical basis that can guide the ...

In this thesis, we present a theoretical study on the current-induced nucleation and propagation of antiferromagnetic skyrmionium. A skyrmionium, also known as 2π-skyrmion, is a vortex-like magnetic structure characterized ...

Magnetohydrodynamics (MHD) boundary layer flow problems have become important in industrial manufacturing processes such as plasma studies, chemical engineering, electrochemistry, polymer processing, petroleum industries, ...

Graphene is an effectively two dimensional form of carbon atoms arranged in honeycomb lattice. Due to its lightweight, high electron mobility and other special electronic properties it is considered both an academically ...

We have studied a model for a non-collinear but coplanar antiferromagnetic spin texture on a two dimensional kagome lattice structure in the presence of Dzyaloshinskii-Moriya Interaction (DMI). We observed some interesting ...

Density-Functional Theory (DFT) offers a simplification to electronic structure problems by using the electron density instead of the wave-function. Unlike the wave-function which is a function of 3N variables (excluding ...

In this thesis we explored the production of highly coherent and energetic extreme ultra violet(XUV) radiation through the process of high harmonic generation(HHG). HHG is a process by which a ultrashort laser pulse interact ...
