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 ...

The advent of dedicated surveys for studying transient events has invoked a great interest in the study of supernovae (SNe). The rate of discovery of SNe has hence gone up ten-fold relinquishing their diversity. SNe not ...

Evolution of galaxies is a phenomenon that affects the formation and composition of galaxies, and the intergalactic medium. It is mediated by processes that establish a symbiotic relationship between a galaxy and the ...

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, ...

Projective measurement is used as a fundamental axiom in quantum mechanics, even though it is discontinuous and cannot predict which measured operator eigen state will be observed in which experimental run. The probabilistic ...

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 ...
