Exploring dissipation dynamics in low-dimensional superconductor
Technological advances in the past decade in fabricating two-dimensional superconducting materials with low disorder have enabled exploring many exciting phases. In recent times, two-dimensional superconductors have been ...
Investigation of Optical and Electro-optical Effects at Material Interfaces
The key questions addressed in this thesis are related to light-matter interactions at the material interfaces and are related to both plasmonic as well as Pockels effects. Plasmonics enables the design of compact photonic ...
Linear and Nonlinear Ultrafast Time Resolved Spectroscopy of Topological Insulators, Weyl Semimetals and Semiconducting Nanowires
Ultrafast time resolved spectroscopy has recently gained immense significance due to its potential capability to explore the dynamics of photoexcited carriers in condensed matter systems. The technique has proved to be a ...
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 ...
Statistics of Conductance Fluctuations in 2D systems
Study of 2D materials is interesting due to the various phase transitions observed
in these materials. I shall present the results obtained in the study of phase transi tions in three different 2D material systems – ...
Investigating spin transport across magnetic insulators and their interfaces
Spin transport across magnetic insulator/heavy metal (MI/HM) interfaces has been a topic of interest
in spintronics. The spin Seebeck effect (SSE) and spin Hall magnetoresistance (SMR) are two
phenomena that have ...
Realization of magnetic Weyl semimetallic phase in pyrochlore iridates thin films
Weyl semimetals (WSMs) are characterized by two linear non-degenerate band crossing inside the bulk of the Brillouin zone. The spin-degeneracy of the bands can be lifted by either
broken inversion symmetry or broken ...
Ultrastrong coupling in a cavity-electromechanical device
Cavity optomechanics is a field that explores the interaction between light and motion of matter via radiation pressure force. Such systems mainly consist of an optical/microwave cavity coupled to a mechanical resonator. ...
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. ...
Fluctuation Driven Collective Phenomena in Electron Doped Quantum Paraelectric: KTaO3
The study of quantum phase transitions, in which a system undergoes a change in its ground state and physical properties due to quantum fluctuations at absolute zero temperature, stands as one of the most celebrated themes ...
