Quantum emitters-integrated flat optics using the guided mode-resonant metasurface and the hyperbolic metamaterial
Solid-state quantum emitters are efficient, scalable single-photon sources with tunable properties of quantum yields and dipole oscillator strengths. Such emitters are emerging sources for a myriad of near-field light-matter ... -
Nonreciprocity, condensation and chirality in active granular systems
We present a journey into the rich non-equilibrium phenomena of active granular systems, a versatile model for studying “living” materials. Our exploration begins with the discovery of non-reciprocal, medium-mediated ... -
Modeling the solar magnetic cycle
The intriguing variety of activities displayed by the Sun naturally awakens human curiosity. Also, by virtue of its physical proximity, the Sun serves as an excellent astrophysical laboratory for testing our theoretical ... -
Investigating Nucleosynthesis During Formation of Black Holes and Extracting Their Properties
Measurement of black hole spins is of great interest to physicists in general and to astrophysicists in particular, as this provides a direct proof of the theory of general relativity for rotating black holes. It involves ... -
Electronic analogue methods in X ray Crystallography
Among the advantages of the structure factor computer described here are the following: (i) Use of standard components throughout, and very little wiring requirements, thus ensuring great ease in mass production. (ii) Very ... -
High rydberg state recombination lines from interstellar carbon : an observational study
This thesis describes the results of an observational study of partially ionized gas in the Galaxy using low-frequency radio recombination lines of carbon, which arise due to electronic transitions at large quantum numbers ... -
Advanced wavefront sensing algorithms in astronomical adaptive optical syatems
Atmospheric turbulence limits the quality of imaging in ground-based astronomical telescopes (Hart; 2010). To obtain diffraction-limited imaging, there is a need for a technology that removes the effects of atmospheric ... -
Growth and study of certain physical properties of KTiOPO4 single crystals
The crystal growth of KTP (Potassium Titanyl Phosphate) from K?P?O?? solvent has been carried out by spontaneous crystallization as well as the top-seeded solution growth (TSSG) technique. For TSSG, a crystal growth system ... -
Phase separation and dynamics of concentrated colloids : Diffusing wave spectroscopy and brownian dynamics simulations
The purpose of this chapter is to summarize the principal results and conclusions reported in this thesis and also to point out the scope of further work. The focus of this thesis is on static and dynamic aspects of the ...
