Skyrmions in arbitrarily polarized quantum Hall states
Sudhansu S. Mandal, V. Ravishankar
We derive an effective non-linear sigma model for quantum hall systems with arbitrary polarizations, by employing the recently proposed doublet model. We study the topological exci…
Activated resistivities in the integer quantum Hall effect
Sudhansu S. Mandal, V. Ravishankar
We have determined the off-diagonal and diagonal conductivities for a quantum Hall effect system at exactly integer filling at finite temperatures and in the presence of weak short…
Novel Finite Temperature Conductivity in Quantum Hall Systems
Sudhansu S. Mandal, S. Ramaswamy, V. Ravishankar
We study quantum Hall systems (mainly the integer case) at finite temperatures and show that there is a novel temperature dependence even for a pure system, thanks to the `anomalou…
Wave functions for arbitrarily Polarized Quantum Hall States
Sudhansu S. Mandal, V. Ravishankar
We determine the wave functions for arbitrarily polarized quantum Hall states by employing the doublet model which has been proposed recently to describe arbitrarily polarized quan…
Chern-Simons Superconductivity at finite magnetic field
Sudhansu S. Mandal, S. Ramaswamy, V. Ravishankar
We study Chern-Simons (CS) superconductivity in the presence of uniform external magnetic field of {\it arbitrary strength} for a system of fermions in two spatial dimensions, whic…
