Fluids, Anomalies and the Chiral Magnetic Effect: A Group-theoretic Formulation
V. P. Nair, Rashmi Ray, Shubho Roy
It is possible to formulate fluid dynamics in terms of group-valued variables. This is particularly suited to the cases where the fluid has nonabelian charges and is coupled to non…
Some topological issues for ferromagnets and fluids
V. P. Nair, Rashmi Ray
We analyze the canonical structure of a continuum model of ferromagnets and clarify known difficulties in defining a momentum density. The moments of the momentum density correspon…
Multiple Edges of a Quantum Hall System in a Strong Electric Field
Rashmi Ray, Joan Soto
In this article we show that if the electrons in a quantum Hall sample are subjected to a constant electric field in the plane of the material, comparable in magnitude to the backg…
The Inhomogeneity Expansion for Planar Q.E.D in a Magnetic Background
Gil Gat, Alpan Raval, Rashmi Ray
The effective action for Q.E.D in external magnetic field is constructed using the method of inhomogeneity expansion. We first treat the non-relativistic case where a Chern-Simons…
Anomalous Magnetic Moment of Anyons
Gil Gat, Rashmi Ray
The anomalous magnetic moment of anyons is calculated to leading order in a 1/N expansion. It is shown that the gyromagnetic ratio g remains 2 to the leading order in 1/N. This res…
Finite Temperature and Density Effects in Planar Q.E.D
G. Gat, R. Ray
The behavior of finite temperature planar electrodynamics is investigated. We calculate the static as well as dynamic characteristic functions using real time formalism. The temper…
