Condensed matter physics is a fascinating subject where collective properties of many particle systems show exotic emergent phenomena, practically unpredictable from the behavior of individual constituents. Many basic ...

In this thesis, first-principles density functional theory (DFT) calculations are used to study the structural, electronic, elastic, mechanical, and thermal properties in a series of pyrochlore materials. The vibrational ...

The successful exfoliation of graphene in 2004 ushered in the era of 2D van der Waals materials, paving the way for a wide variety of applications in the field of electronics, optoelectronics, sensors, catalysis, flexible ...

Composites are the advanced engineering materials invented by men with exceptional properties over traditional materials. These attractive and delightful materials are the result of developments in the area of engineering ...

This thesis discusses experimental studies with vapor cells containing rubidium (Rb) or cesium (Cs) atoms. Transitions in the atoms (D1 and D2 lines) are accessed using diode lasers. Experiments are performed at room ...

Despite the central role that Equilibrium thermodynamics has played in our understanding of many body systems, the underlying theoretical construct is strictly correct only in the ‘Thermodynamic Limit’. On the other hand, ...

When two planar atomic or molecular layers are brought to sub-nanometer proximity, they form a van der Waals interface because the van der Waals force forms the dominant attractive force between them. The van der Waals ...

Thermodynamics and Statistical Mechanics of Multi-colored Loop models in three dimensions: A Monte-Carlo study. Soumya Kanti Ganguly Department of Physics. ABSTRACT A perfectly crystalline solid is a regular ...

In recent days, the need for device miniaturization has led to immense research activities in the field of material science. It has become essential to discover and design new materials or to modify the existing materials ...

Almost 80% of the world’s energy needs depend on oil, coal and natural gases. Use of natural gases, fossil fuels emit a large amount of CO2 to the earth’s atmosphere, which causes the greenhouse effect and results in an ...
