Exploring Transition Metal Oxides Towards Development of New Functional Materials : Lithium-ion Battery Cathodes, Inorganic Pigments And Frustrated Magnetic Perovskite Oxides
(2017-10-11)
Transition metals (TMs) are ‘elements whose atoms have partially filled d-shell, or which can give rise to cations with an incomplete d-shell’. In TMs, the d-shell overlaps with next higher s-shell. Most of the TMs exhibit ...
Real-Time DMRG Dynamics Of Spin And Charge Transport In Low-Dimensional Strongly Correlated Fermionic Systems
(2014-12-11)
This thesis deals with out-of-equilibrium transport phenomena in strongly correlated low-dimensional fermionic systems, with special emphasis on π-conjugated molecular materials. The focus of this work is to study real-time ...
