Activity induced phase separation and the emergence of liquid crystal phases in chiral and achiral systems, and development of an efficient method to compute the entropy of various liquid crystal phases
The phase behaviour of shape-anisotropic particles is an emerging field of research that
gives rise to various liquid crystal phases. In this thesis, we explore various equilibrium and
non-equilibrium properties of ...
Active matter: chirality, translational order, and interfaces
My PhD work is on chiral active matter with solid and fluid directions, dynamics of the
interface of a nonconserved chiral order parameter in an active system, flocking on curved
manifolds and field-driven colloids in ...
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 ...
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 ...
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 ...
