The primary goal of this thesis is to develop a light sheet based microscopy system that provides non-invasive images having high spatial and temporal resolution. The fluorescence microscopy has become an indispensable ...

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 ...

The key aspect of this thesis is to understand the photoinduced carrier dynamics in low dimensional systems by employing time resolved optical pump-terahertz probe (OPTP) spectroscopy. Ultrafast pulsed laser (Ti: Sapphire ...

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 ...

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 ...

Topological insulators (TIs) belong to a new class of materials characterized by linear surface states, which emerge in the bulk band gap due to non-trivial topology of the band structure. These surface states have various ...

Emergence of Graphene, Transition metal dichalcogenides (TMDCs) and other van der Waals materials promises to rede fine the building blocks of the future materials and technologies. These materials have gained enormous ...

An electron entering liquid helium experiences a repulsive potential of 1 eV. This originates in the interaction between the injected electron and electrons of the closed shells of helium atoms through Pauli exclusion ...

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 ...
