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 ...

The thesis endeavours to theoretically understand electronic properties of nite trapezoidal shaped graphene sheets, and understand zero energy edge states. The motivation for this thesis is recent experimental work at Low ...

There has been much interest in the glassy dynamics of living systems at the scales of subcellular structures, cells and tissues. This has motivated theoretical studies on the approach to glassy behaviour in dense systems ...

In this thesis we study a novel soft-matter system that imitates motility. Our system consists of a few asymmetrically tapered brass rods and aluminium beads which are confined between two vertically shaking plates. The ...

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 ...

Doped rare-earth manganites with the general formula T1􀀀xDxMnO3 where `T' is a trivalent rare earth ion, e.g. La3+;Nd3+; Pr3+ etc. and `D' is a divalent alkaline earth ion, e.g Ca2+; Sr2+;Ba2+ etc. display various ...

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 ...
