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. ...
Collective Magnetic Phases with Pentavalent Iridates
Magnetism and magnetism-driven phenomena have always remained a central theme
of modern condensed matter physics. Conventional magnetic transition, such as para magnetic to ferromagnetic phase, involves symmetry breaking ...
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 ...
Charge Transport in PEDOT:PSS and Blends
Charge transport properties and metal-insulator transition in conducting polymers de pend on doping, disorder and the complex nanomorphology. Conductivity of poly(3,4-
ethylenedioxythiophene):poly(styrene-sulfonate) ...
Electro-optic charge transport in semiconducting polymers
In this thesis, I have discussed the electric field dependence of photoconductivity of regioregular poly(3-hexylthiophene) [rr-P3HT] and its sensitization with Squaraine (SQ) dye. Even 1 wt % of SQ dye enhances the transport ...
Chaos, entanglement, and non-equilibrium dynamics in Hermitian and non-Hermitian quantum many-body systems
Quantum chaos and entanglement have appeared as two key intertwined concepts to characterize fundamental quantum correlations of quantum many-body states and to understand the emergence of thermal and non-thermal steady ...
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 ...
Interfacial - Dzyaloshinskii - Moriya interaction in quasi-perpendicularly magnetized Ta/Pt/CoFeB/Pt ultra-thin films
The physics of Ferromagnetic-Metal/Heavy-Metal(FM/HM) ultra-thin film heterostructures is not only rich enough to investigate the interplay of magnetic interactions but also relevant enough to harness a new paradigm of ...
Role of Oxygen Vacancies in Modification of Electronic Structure of Bulk Oxides
Emergent phenomena in oxides have been receiving a lot of experimental and theoretical interest in the recent decade. In general, oxides host a rich diversity of defects and several new emergent phenomena such as 2-DEG ...
