Search for dark matter produced in association with b-jets in proton-proton collisions at √s = 13 TeV with the CMS detector using full Run2 data
A search for dark matter particles in the events containing large missing transverse energy accompanied by b-quarks has been performed. The data collected by the Compact Muon Solenoid detector at the Large Hadron Collider ... -
Understanding the vertical structure of galactic stellar disc and the role of interstellar gas and dark matter halo
The aim of this thesis is to understand the dynamical effect of interstellar gas and dark matter halo on the vertical distribution of stars in our Galaxy as well as modeling the stellar distribution in a generalized and ... -
A Platform for Handheld Ultrafast PCR
The Polymerase Chain Reaction (PCR) is one of the most sensitive and specific diagnostic tools available today. Yet, it stands out of reach for many vulnerable populations because commercial solutions are expensive, bulky, ... -
Study of light-matter interactions in ultra-low noise graphene-based van der Waals hybrid
The vast array of optical and electrical capabilities of graphene (Gr) and analogous two dimensional (2D) van der Waals (vdW) materials have piqued scientists’ interest for long. Stacking these materials to form hybrid ... -
Searches for Higgs boson pair production in bbbb and bbgammagamma final states at Compact Muon Solenoid detector
The discovery of the Higgs boson makes the Standard Model (SM) a promising theory to understand fundamental physics. Despite its progress, the theory does not explain many observed phenomena such as dark matter and hierarchy ... -
Investigation of DC and AC Charge Transport in Semiconducting Polymers and Devices
Semiconducting polymer materials have several applications in electronics and optoelectronic devices. The charge transport in these complex systems is yet to be fully understood to optimize the performance of the devices. ... -
Unraveling certain high energy astrophysical features based on advective accretion disks
The presence of an accretion disk around a neutron star (NS) or a black hole (BH) is mainly responsible for the observed X-rays from the night sky. NS or BH is a part of the binary systems, and matter flows from a companion ... -
Understanding Nucleic Acid Charge Transport Properties using Multiscale Modelling Techniques
Understanding charge transport in molecular systems is of fundamental interest in rapidly growing field of molecular electronics as well as to understand biological signal transfer processes which are accompanied by the ... -
The multiphase interstellar medium: A study of various physical and kinematical properties
Interstellar medium (ISM) is the relatively empty space in between the stars. It has different phases, like, neutral, molecular, and ionized. Neutral interstellar medium, which is pervaded all over the galaxy, is sometimes ... -
Role of Friction in Microswimmer and Active Filament Motion
Friction is pervasive in all fields of science. It is the key factor that emerging technologies involving autonomous motion at micron scales such as micro-bots need to overcome in order to be efficient. They fall in the ... -
Exploring carrier dynamics in van-der-Waals heterostructures with shot noise spectroscopy, thermoelectricity and opto-electronic study
In the last two decades, there has been tremendous progress in two-dimensional (2D) - material research. It is mainly due to the availability of a large selection of 2D-materials and their van-der-Waals heterostructures. ... -
Design and Development of Fiber Bragg Grating Tactile Sensing Devices for Novel Applications in Engineering and Biomedical Fields
Among the five human basic senses, touch is thought to be the sense that makes the world 'real' to us. Tactile sensors are a category of artificial sensors that acquire information through physical touch. Tactile sensors ... -
Development of Graphene Palladium Nanocomposite based Flexible Sensors for Strain and Temperature Measurement
In recent years, device manufacturing technology has been shifted from bulk and thin-film materials to nanomaterials, which are emerged as a unique class of materials. Among all the two-dimensional (2D) nanomaterials, ... -
Electronic structure of two-dimensional materials: Effect of point defects and moiré patterns
In the last two decades, research on two-dimensional (2D) materials has gained momentum due to their capability to host a wide range of novel phases of matter. These materials have also found applications in electronic, ... -
Fundamental aspects of the interface engineering in the heavy metal/ferromagnet-based perpendicularly magnetized systems
The ferromagnetic (FM) material finds its applications due to the property of spontaneous magnetization. An FM object can hold its state of magnetization unless any external stimuli change it. The easy manipulation of its ... -
