Bulk and edge excitations of a Hall ferromagnet
Rashmi Ray, B. Sakita
In this article, we shall focus on the collective dynamics of the fermions in a quantum Hall droplet. Specifically, we propose to look at the quantum Hall ferromagnet. In th…

Quantum Hall Ferromagnets: Induced Topological term and electromagnetic interactions
Rashmi Ray
The quantum Hall ground state in materials like GaAs is well known to be ferromagnetic in nature. The exchange part of the Coulomb interaction provides the necessary attract…
Electromagnetic Interactions in the Quantum Hall Ferromagnet
Rashmi Ray
The quantum Hall ground state in samples like GaAs is well known to be ferromagnetic. The global SU(2) spin symmetry of the microscopic action is broken down to a U(1) symmet…
Field Theoretical Approach To Quantum Hall Ferromagnets
Rashmi Ray, Joan Soto
We present a quantum field theoretical analysis of a quantum Hall system when the effective Landé factor is small. We clearly demonstrate that the ground state of the sy…
