Numerical studies of low energy behaviour of a few spin ladders and magnetic field effects in heavy fermions

Parihari, Debabrata (Jawaharlal Nehru Centre for Advanced Scientific ResearchTheoretical Sciences Unit (TSU), 2008)

The underlying theme thoughout this thesis is the study of materials belonging to the class of strongly correlated electronic systems (SCES). These are systems where the coulomb interaction energy due to electron repulsion ...
Theoretical study of metal ion substituted CeO2 for environmental catalysis: origin of oxygen storage capacity hydrogen spillover and carbon monoxide oxidation

Dutta, Gargi (Jawaharlal Nehru Centre for Advanced Scientific ResearchTheoretical Sciences Unit (TSU), 2008)

The industrial development in today's world has led to challenges in the environment due to pullution. Consumption of fossil fuels such as coal, nutual gas and oil produces has led to many harnful by-products by combustion.
Theoretical investigations of electronic structure and charge transfer properties of DNA and modified DNA

Mallajosyula, Sairam Swaroop (Jawaharlal Nehru Centre for Advanced Scientific ResearchTheoretical Sciences Unit (TSU), 2009)

Nucleic acids have been shown to be central molecules in transmission, expression, and conservation of genetic information. The classic experiments by Avery et al.[1] and Hershey et al.[2] demonstrated the role of ...
Modelling and Simulations of Structures and Structural Transitions

Paul, Jaita (Jawaharlal Nehru Centre for Advanced Scientific ResearchTheoretical Sciences Unit (TSU), 2009)

The main themes of the work presented in this thesis were, broadly, motivated by ideas of designing newer and more compact nano-structured materials for information storage. Both ferroelectric and ferromagnetic materials ...
First-principles study of one-dimensional nano-structures

Kahaly, Mousumi Upadhyay (Jawaharlal Nehru Centre for Advanced Scientific ResearchTheoretical Sciences Unit (TSU), 2009)

The study of solid state system was mainly restricted to three dimensional bulk systems and two-dimesional surfaces, till 1960's. However, recent years have witnessed highly sophisticated miniaturization techniques and ...

A generalized landau-theoretical analysis of defect states of order-parameter near ferroelectric phase transitions

R, Arun (Jawaharlal Nehru Centre for Advanced ScientificTheoretical Sciences Unit (TSU), 2010)

In this thesis, the author wishes to describe the development and subsequent use of a computational tool that can help analyse the defect-states of the order parameter field that form near ferroelectric phase transitions, within ...
Theoretical modeling of some low dimensional quantum spin systems and charge transport in a few organic materials

Mohakud, Sasmita (Jawaharlal Nehru Centre for Advanced Scientific ResearchTheoretical Sciences Unit (TSU), 2010)

Electronic correlations play the central role in governing many fundamental aspects of materials, which include excitation characteristics, thermodynamic and dynamic behavior of systems, ranging from small molecules to ...
Computer simulation study of phase behavior and structural relaxation in a gel modeled by three body interactions

Saw, Shibu (Jawaharlal Nehru Centre for Advanced Scientific ResearchTheoretical Sciences Unit (TSU), 2010)

According to the Encyclopedia Britannica a gel is a coherent mass consisting of a liquid in which particles too small to be seen in an ordinary optical microscope are either dispersed or arranged in a fine network ...
