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 ...
Ultrafast Response And Time Resolved Spectroscopy Of Carbon Nanotubes, Semiconductors And Rare-Earth Titanates Using Femtosecond Laser Pulses
(2013-10-21)
In this thesis, experimental studies are reported of ultrafast dynamics and third order optical nonlinear coefficients of carbon nanotubes, and time resolved coherent phonon dynamics of semiconductors and rare earth ...
Dynamics of Glass-Forming Liquids and Shear-Induced Grain Growth in Dense Colloidal Suspensions
(2018-06-19)
The work presented in this doctoral thesis employs colloidal suspensions to explore key open problems in condensed matter physics. Colloidal suspensions, along with gels, polymers, emulsions and liquid crystals belong to ...
Slow Dynamics In Complex Fluids : Confined Polymers And Soft Colloids
(2015-08-05)
The thesis describes the study of slow dynamics of confined polymers and
soft colloids. We study the finite size effect on the dynamics of glassy polymers
using newly developed interfacial microrheology technique. ...
Preparation and Optical Properties of Hybrid Assemblies of Metallic Gold Nanoparticles and Semi-Conducting CdSe Quantum Dots
(2018-04-16)
This thesis summarizes the methods of preparation and optical properties of hybrid assemblies of Au NPs and cadmium selenide (CdSe) QDs. First chap-ter deals with the literature survey and theoretical aspects of plasmonics ...
Thin Film Instabilities Mediated Self-Assembly of Polymer Grafted Nanoparticles
(2018-07-18)
After the advent of nanotechnology, self-assembly has become an active area of research, as it being one of the few efficient methods to generate ensembles of nanostructures. In this thesis, we present studies on two ...
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., ...
