Non-Hermitian Quantum Theory via Hermitian Operators: A Unified Framework with Application to Anyons
Non-Hermitian (NH) operators are more prevalent than we often recognize across a variety of domains. They naturally arise in diverse open system settings such as photonic lattices, non- equilibrium statistical mechanics, ... -
Investigation of Thermal Stability and Functional Dynamics of Nucleic Acid Nanostructures using Molecular Dynamics Simulations
DNA has emerged not only as the carrier of genetic information but also as one of the most studied and most versatile nanoscale materials in modern science. Since Ned Seeman first proposed the concept of DNA nanotechnology ... -
Growth and characterisation of Indium antimonide and its heterosturctures
In conclusion, InSboriented layers have been grown on InSb and GaAs by LPE. While stepcooling yielded good homoepitaxial layers, it was necessary to use the rampcooling technique to grow InSb on GaAs. The narrow rockingcurve ... -
Studies on selected semiorganic and organic nonlinear optical crystals
Good opticalquality LAP and dLAP crystals were grown from aqueous solutions by solvent evaporation and slow cooling. Problems associated with crystal growth, such as microbial growth in the solution, were systematically ... -
Electriacl and theramal studies on metal doped germanium telluride glasses
Cu-Ge-Te Glasses (i) Bulk, meltquenched CuGeTe glasses are found to exhibit a single glass transition and a singlestage crystallization upon heating. (ii) The composition dependence of the glasstransition temperature, ... -
Crystal growth and characterization of some nonlinear optical materials
Single crystals of LAP were grown from aqueous solution under different growth conditions. The undesirable growth of microorganisms was avoided by protecting the surface of the solution by placing a thick layer of nhexane ... -
White dwarf pulsators-a study with the whole earth telescope
We have presented in this thesis the first observational results on the location of the driving region and the processes involved in white dwarf pulsations. We selected one object from each of the three main instability ... -
Experimental investigations on the structure and transport properties of amorphous and nano-crystalline carbon nitride
In this chapter, we summarize our results and present concluding remarks on our investigations. Key findings on amorphous carbon nitride are followed by results on crystalline carbon nitride. Carbon and its allotropes ... -

Spectroscopic studies on polymerized and doped fullerenes and pressure induced phase transition in BaTiO3
In conclusion, we have observed pressure induced polymerization in the case of C but not in C . This calls for detailed theoretical analysis, incorporating the changes in electronic structure with the application of ... -
Bulk and thin growth of pure and substitued indium antimonide for infrared detector applications
InSb single crystals were grown by the vertical and horizontal Bridgman techniques. About 81 experimental runs were carried out altogether (for 8 mm, 10 mm and 20 mm diameter InSb crystals). Among them, as many as 47 runs ... -
Investigations of electroporation physics using optically transparent polymer devices and molecular dynamics simulation
New technologies have emerged in the medical field over the last decade to treat problems such as cancer and tumors. Electroporation is one such technique that has been extensively used in electrochemotherapy, drug delivery, ... -
Crystal structure of a light-harvesting protein C-phycocyanin from spirulina platensis and bioinformatics analysis of beta-bulge turns in proteins
The conclusions for the crystal structure of light-harvesting phycobiliprotein, C-phycocyanin from an important cyanobacterium, Spirulina platensis, are summarized as follows: We have solved the three-dimensional structure ... -
Investigations of AC response in certain type II superconductors
We have intentionally varied the microstructures of polycrystalline YBCO samples and studied their AC loss behavior. A close correlation between AC losses and the microstructures of the superconducting samples is observed. ... -
Investigations in X-ray crystallography
he crystal structure of glycine silver(I) nitrate has been solved in the non-ferroelectric phase by the heavy atom technique and refined to an R value of about 11% with four sets of intensity data, three sets collected at ...
