Light and magnetic field induced coherence effects in atoms
In this thesis, we have studied the coherence effects in atoms induced by light and a magnetic field. After giving an introduction to the contents of the thesis, details about the theory and the experimental setup used are ... -
Wearable Sensors using Solution Processed 2D Materials
Wearable sensors, as the name implies, are devices that can be donned onto the body in order to continuously detect, monitor and analyze various signals generated by the subject and the immediate surroundings. Applications ... -
Electric Field Assisted Self-Healing (eFASH)
Circuit failure due to the open faults in the interconnect is the most common problem regarding the reliability of electronic systems. This is particularly true for large-area electronic systems such as display, image ... -
Fabrication and Characterization of Multilayer MoS2 Coated Etched Fiber Bragg Grating Sensors and Side-hole Packaged Fiber Bragg Grating Sensors with Enhanced sensitivity for Different Applications
In summary, MoS2 coated, etched FBG sensors have been used for various applications. Firstly, the strain sensitivity has been studied; a high strain sensitivity of 6.3 pm/μɛ with a linear range of sensing response from 0 ... -
Correlation Functions in the Finite Toom Model
This thesis is divided into four chapters. In Chapter 1, we give some basic definitions and results that we need throughout the thesis. In Chapter 2, we describe the pn0;n1q-Toom model and prove some known results about ... -
Duality for Spaces of Holomorphic Functions into a Locally Convex Topological Vector Space
Consider an open subset O of the complex plane and a function f : O ÝÑ C. We understand the concept of holomorphicity of a complex-valued function. Suppose a function f defined on O takes values in a locally convex ... -
A Study of Some Conformal Metrics and Invariants on Planar Domains
The main aim of this thesis is to explain the behaviour of some conformal metrics and invariants near a smooth boundary point of a domain in the complex plane. We will be interested in the invariants associated to the ... -
Decomposition of the tensor product of Hilbert modules via the jet construction and weakly homogeneous operators
Let ½ Cm be a bounded domain and K :£!C be a sesqui-analytic function. We show that if ®,¯ È 0 be such that the functions K® and K¯, defined on £, are non-negative definite kernels, then theMm(C) valued function ... -
Interplay of Interaction and Topology From Topological Band Theory to Topological Field Theory
Classification of phases of matter has long been a central point of interest in the research community in condensed matter physics. Over the past several decades mainly two kinds of classification schemes have emerged, ... -
Heavy flavour and direct photon probes of the gluon Sivers function
Traditionally the production of heavy quarkonia, heavy-flavour mesons as well as of direct photons, has been used to constrain the gluon density inside the proton. In this thesis, I have assessed various heavy flavour ... -
Frequency and Temperature Dependent Mechanical Behavior of Three-Dimensional Cellular Structures of Graphene and Carbon Nanotubes: Role of Microscopic Interfacial Interaction
Three dimensional (3D) cellular structures with high mechanical strength and stability are recently proven to provide a crucial platform for multifunctional application in various fields namely biomedical, soft robotics, ... -
Trace Estimate For The Determinant Operator And K- Homogeneous Operators
Let $\boldsymbol T=(T_1, \ldots , T_d)$ be a $d$- tuple of commuting operators on a Hilbert space $\mathcal H$. Assume that $\boldsymbol T$ is hyponormal, that is, $\big [\!\!\big [ \boldsymbol T^*, \boldsymbol T \big ]\!\! ... -
Point-of-need analyte detection using dsDNA-templated fluorescent copper nanoparticles
The detection of various types of pollutants, toxins, and adulterants that are detrimental to the environment and human health is essential for monitoring air, water, soil, and food quality. Technologies that enable the ... -
Probing phase transition and anisotropy in magnetic insulator based heterostructures employing magnon spin currents
Thermoelectric phenomena like the Seebeck and Peltier effects are known for more than two centuries with a wide range of applications. In 2008 Uchida et al. first demonstrated the phenomena called Spin Seebeck Effect (SSE) ... -
Particles and Fields in Partial-differential-equation Models for fluid and Superfluid Turbulence
We have shown that uniformly rotating vortex-containing gravitationally-bound solutions of the GPPE can be generated by starting the evolution from initial data obtained by integrating to convergence the (imaginary-time) ... -
