Electronic behavior of epitaxial thin films of doped rare-earth nickelates
Rare-earth nickelates (RENiO3), a family of transition metal oxides, exhibit a complex phase diagram involving electronic, magnetic, and structural phase transitions. While LaNiO3 remains paramagnetic, metallic down to ... -
Electronic structure of strongly correlated Systems from Ab-initio and model Hamiltonion approaches
Strong electron–electron interactions profoundly influence the properties of systems such as transition-metal, rare-earth, and actinide-based compounds, giving rise to a variety of exotic phenomena. In recent times, there ... -
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, ... -
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 ... -
Emergent Phenomena from Contacts and Disorder in High Mobility Graphene
The discovery of graphene and analogous van der Waals materials offers a platform for the discovery and exploration of various novel physical phenomena. Here we study the effects of local interaction and strong localisation ... -
Engineering Plasmonic Interactions in Three Dimensional Nanostructured Systems
(2018-02-08)Strong light matter interactions in metallic nanoparticles (NPs), especially those made of noble metals such as Gold and Silver is at the heart of much ongoing research in nanoplasmonics. Individual NPs can support collective ... -
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 ... -
Engineering Weyl and Dirac Fermions in Transition Metal Perovskites
The emergence of topological materials has fundamentally altered the landscape of condensed matter physics, introducing phases of matter defined by the topological properties of their electronic wavefunctions. A particularly ... -
Enhancing the spin-orbit torque efficiency in Pt/CoFeB/Pt based perpendicularly magnetized systems
Controlling and switching magnetization by the process of current-induced torque has a considerable advantage in lower power consumption for a memory device and spin logic device application. For a heavy metal (HM) / ... -
Entangled Granular Chains: Geometry, Cohesion, and Emergent Mechanics
Granular materials, composed of discrete macroscopic particles, are ubiquitous in daily life, industry, and natural processes. Unlike conventional solids or liquids, their behavior is complex, driven by dissipative ... -
EPR study of the phase transitions in LIKSO4 and certain similar salts.
This thesis represents basically an attempt to investigate the low temperature phase transitions of LiKSO^ (LKS) through Electron Paramagnetic Resonance (EPR). There have been of course umpteen publications on the ... -
Equilibrium and nonequilibrium dynamics of dense liquids
Dense liquids do many interesting things: they freeze into crystals, and sometimes get trapped into glassy states along the way. Their behaviour becomes more unusual when they are driven far away from equilibrium, for ... -
Esperimental techniques and of electrical properties of critical binary liquid systems
A direct analysis of the resistance and capacitance data did not yield any unambiguous result on the value of the exponent ?. Both resistance and capacitance behave in a similar way, and the ? value seems to depend upon ... -
Establishing Super- and Sub-Chandrasekar Limiting Mass White Dwarfs to Explain Peculiar Type La Supernovae
(2018-06-23)A white dwarf is most likely the end stage of a low mass star like our Sun, which results when the parent star consumes all the hydrogen in its core, thus bringing fusion to a halt. It is a dense and compact object, where ... -
Evolution of the Magnetic Ground States with Lattice Distortion and Chemical Inhomogeneity in Doped Perovskite Oxides
(2018-04-18)The physics of doped transition metal perovskite has been an area of intense research in the last few decades due to their interesting magnetic and transport properties. Various exciting phenomena such as, colossal magneto ... -
Exchange Spring Behaviour in Magnetic Oxides
(2018-02-23)When a permanent magnet is considered for an application, the quantity that quantifies the usability of that material is the magnetic energy product (BH)max. In today’s world, rare earth transition metal permanent magnets ... -
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 ... -
