Aspects of low-dimensional quantum systems in and out-of-equilibrium
The classification of novel phases of matter beyond the Landau paradigm has been comprehensively explored over the past decade. In this context, one-dimensional quantum systems are particularly promising, as they host ... -
Complex magnetism and structural phase transition in correlated oxide systems
Perovskite and pyrochlore materials constitute a profoundly intriguing and extensively studied family owing to their diverse magnetic and structural properties. we thoroughly explored the structure and magnetism of the ... -
Computation of Induced Eddy Currents in Axially Symmetric Geometries Using the Coupled Inductor Method
The computation of eddy currents is essential in applications including induction heating, magnetic levitation, and non-destructive testing. Usually, the numerical solution of partial differential equations derived from ... -
Confronting realistic MHD simulations of solar eruptions with observed space based data
Solar flares and Coronal Mass Ejections (CMEs) are among the most violent and energetic phenomena observed in the solar atmosphere, resulting from the sudden release of immense amounts of energy. A typical solar flare is ... -
Crystal Structure of an Effector Histone Methyltransferase Rv2067c from Mycobacterium tuberculosis H37Rv: Structural Insights into Context-Dependent Substrate Recognition Structure and Dynamics of a GNAT Family Protein Acetyltransferase HP0935 from a Gastric Pathogen Helicobacter pylori 26695
Methylation of histones is one of the important gene regulation mechanisms in eukaryotes. Histone methylation has a role in immune response to the invading pathogens. Pathogens implement effector proteins that evade host ... -
Development of Inorganic Perovskite Nanocrystals for Optoelectronic Applications
Metal Halide Perovskites (APbX3) have garnered appreciable attention from researchers because of their fascinating optoelectronic properties. These properties include high absorption coefficient, defect tolerance, long ... -
Dielectric property studies on Poly vinylidene fluoride composites with Graphene Oxide and functionalized Carbon nanotube fillers
Embargo up to November 1, 2025 Graphene Oxide (GO) and functionalized Carbon nanotubes (FCNT) are promising materials in the field of polymer composites due to their ability to disperse nicely in the polymer matrix. The ... -
Dielectric, AC Conductivity, and EMI Shielding studies of PEDOT-PSS Nanocomposites with Carbon based Fillers
Polymer nanocomposites (PNCs) have emerged as a significant material for addressing two critical contemporary challenges: the escalating global energy demand and the pervasive electromagnetic interference (EMI) issues. The ... -
Effect of AGN on the ISM of their hosts: A multi-wavelength perspective
Active Galactic Nuclei (AGN) are among the high luminosity (1011 − 1014 L⊙ ) sources in the observable Universe, believed to be powered by the accretion of matter onto supermassive black holes (SMBHs; 105 − 1010 M⊙ ) at ... -
Electrical Transport and Point Contact Spectroscopy in Core-Shell Bimetallic Nanostructures
An extensively pursued strategy for realizing new materials is the creation of interfaces between two similar or dissimilar systems, which can invoke multiple processes like electronic reconstruction, strain-induced ... -
Existence and implications of positively curved metrics on holomorphic vector bundles
This thesis is divided into two parts. In the first part, we study interpolating and uniformly flat hypersurfaces in complex Euclidean space. The study of interpolation and sampling in the Bargmann-Fock spaces on the complex ... -
Explorations of singularities in some hydrodynamical partial differential equations
The global regularity problem for the 3D Euler equations remains unsolved. The presence of finite-time singularities (FTS) can signal the breakdown of the PDE as a physical model for fluid flow; it is also conjectured to ... -
Exploring Application of Dendrimer in Energy Storage, Uranyl Extraction and Drug Delivery through Molecular Modelling
This thesis explores the potential applications of poly(amidoamine) (PAMAM) dendrimers, a class of highly branched polymers, using atomistic molecular dynamics simulations. We investigate the use of PAMAM dendrimers in ... -
Exploring the Fractional Quantum Hall Effect and Electron-Electron Interactions in ABA Trilayer Graphene through Electric Fields
Since the discovery of graphene (a single sheet of carbon atoms) in 2004, the field has expanded with groundbreaking discoveries like the Quantum Hall effect, correlated phenomena, superconductivity, and ferromagnetism. ... -
Galactic cosmic rays from star clusters and nearby supernovae remnants
Cosmic rays (CRs) are high-energy particles, predominantly originating from outside the Earth’s atmosphere. These particles, ranging from protons to heavier nuclei, propagate through space at nearly the speed of light, ... -
Geometry of normed linear spaces in light of Birkhoff-James orthogonality
In this thesis, we have tried to understand the geometry of normed spaces in the light of Birkhoff-James orthogonality. Using the first two chapters to give introductory notes and to establish relevant notations and ... -
