The Cahn-Hilliard-Navier-Stokes Framework for Multiphase Fluid Flows: Laminar, Turbulent, and Active
The Cahn-Hilliard-Navier-Stokes (CHNS) framework has found extensive applications, across diverse length and time scales, for multi-phase flows. In this thesis, we demonstrate that this framework offers a robust theoretical ... -
Charge Transport in Molecular Systems
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 ... -
Collective Phototaxis of Chlamydomonas reinhardtii Cells
Microorganisms are omnipresent in our life and the environment, such as microbes in the gut, spermatozoa in reproductive organs, algae and protozoa in the aquatic ecosystem, and bacterial colonization and infection. ... -
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 ... -
Conductance Fluctuations in High-mobility Graphene Field Effect Transistors
In the past decade, a major fraction of the research carried out in condensed matter physics has been dedicated to address the unique physical properties of single layer graphene (SLG). Different properties of Dirac ... -
Detection of charge-neutral modes to spin-wave excitations in graphene quantum Hall, and periodic magnetic field effect on Dirac electrons
In the quantum Hall (QH) regime, the electrical transport happens along the downstream chiral edge modes (dictated by the external magnetic field) while the bulk remains a vanilla insulator. However, it has been theoretically ... -
Dynamo Action in Rotating and Shearing Flows
Magnetic fields are omnipresent in universe. They play important role in the formation of stars, galaxies and the accretion onto compact objects and the collimation of the relativistic jets of radio galaxies. It is intriguing ... -
Effect of a fast flux line on the coherence of 3D transmon qubits
With the development of the science and technology, the quantum computers are becoming the possible key to reveal new breakthroughs. Unlike the classical computers, where we have classical bits (0or1), in quantum computation ... -
Effect of As and Se substitution on the Phase Change properties of GeTe based alloys
Phase-change memory (PCM) is a key enabling technology for non-volatile electrical data storage at the nanometer scale. A PCM device consists of a small active volume of phase-change material between two electrodes. In ... -
Electrical transport and optical studies of spin-orbit coupled topological phases in different correlation regimes
The interplay of spin-orbit coupling (SOC) and electron-electron correlation in different regimes gave birth to many novel topological phases with exotic properties ranging from quantum transport to superconductivity. One ... -
Electronic transport in low dimensional LaAlO3/SrTiO3 heterointerface
The large variety of phenomena exhibited by the interface between two band-insulators LaAlO3 and SrTiO3 has attracted intense research activity in recent years.The interplay of different symmetries, viz. point group ... -
Engineering topological surface states through structural control, electrostatic gating and superconducting proximity effects
Three dimensional topological insulators are materials characterized by a gapped insulating bulk and gapless metallic states on the sample surface. This unique be- havior arises out of the non-trivial topology of the ... -
Excursions in ill condensed quantum matter from amorphous topological insulators to fractional spins
Condensed matter physics is a fascinating subject where collective properties of many particle systems show exotic emergent phenomena, practically unpredictable from the behavior of individual constituents. Many basic ... -
Experimental Investigation of Electrons In and Above Liquid Helium
Electrons on the surface of liquid helium form a nearly ideal 2-dimensional electron system (2DES). An electron density up to 2 × 10^9 cm-2, known as the critical electron density, can be achieved on the liquid helium ... -
