Ultrafast Photoexcited Carrier Dynamics in Low Dimensional Systems Probed by Time Resolved Terahertz Spectroscopy
The key aspect of this thesis is to understand the photoinduced carrier dynamics in low dimensional systems by employing time resolved optical pump-terahertz probe (OPTP) spectroscopy. Ultrafast pulsed laser (Ti: Sapphire ...
Multiscale Simulation of Nucleic Acid Nanostructures
Nucleic acids, namely DNA and RNA, are arguably the most studied biological molecules. Utilizing the key properties of nucleic acids, such as their persistence lengths and Watson-Crick base-pairing complementarity, ...
Compact objects in exotic premise and underlying gravitational waves
Einstein’s theory of general relativity and quantum mechanics were among the most startling discoveries in the 20th century. Based on these theories, the maximum mass of a non-rotating non-magnetized white dwarf is found ...
Transport, localization and entanglement in disordered and interacting systems: From real space to Fock space
In this thesis, we explore some of the exciting physics of condensed matter systems
manifested because of imperfection or disorder and interactions among the constituent
particles. In phenomena like transport, e.g., ...
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 ...
Electrical waves in mathematical models of human-ventricular tissue: effects of different modeling formalisms, electrophysiological factors, and heterogeneities on ventricular arrhythmias and the termination of these arrhythmias via a deep-learning approach
Sudden cardiac death (SCD) remains one of the significant causes of
mortality in industrialized and developing countries. SCD is often caused by
life-threatening cardiac arrhythmias like ventricular tachycardia and ...
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 ...
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 ...
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 ...
An Investigation of Electronic Phases and Charge Dynamics in Low-Dimensional System
In condensed matter physics, the concepts of topology and symmetry are of paramount importance, particularly in understanding quantum phase transitions. Topology classifies objects based on their topological
properties, ...
