Interaction Driven Quantum Phase Transitions in Fractional Topological Insulators

, 2012
We study two species of (or spin-1/2) fermions with short-range intra-species repulsion in the presence of opposite (effective) magnetic field, each at Landau level filling factor 1/3.

Skyrme insulators: insulators at the brink of superconductivity

, 2017
Current theories of superfluidity are based on the idea of a coherent quantum state with topologically protected, quantized circulation. When this topological protection is absent, as in the case of $^3$He-A, the coherent quantum state no longer supports

Nonlinear DC-response in Composites: a Percolative Study

, 1997
The DC-response, namely the $I$-$V$ and $G$-$V$ charateristics, of a variety of composite materials are in general found to be nonlinear. We attempt to understand the generic nature of the response charactersistics and study the peculiarities associated ...
