Some Unconventional Phases And Phase Transitions In Condensed Matter : Spin-Nematics, Spin-Liquids, Deconfined Critical Points And Graphene NIS Junctions
Condensed matter physics provides us with an opportunity to explore a large variety of systems with diverse properties. Central to the understanding of these systems is a characterization of the nature of their ground ...
Phonon Anomalies And Phase Transitions In Pyrochlore Titanates, Boron Nitride Nanotubes And Multiferroic BiFeO3 : Temperature- And Pressure-Dependent Raman Studies
This thesis presents experimental and related theoretical studies of pyrochlore titanate oxides, boron nitride nanotubes, and multiferroic bismuth ferrite. We have investigated these systems at high pressures and at low ...
