Dissipation and Topologically Massive Gauge Theories in Pseudoeuclidean Plane

TL;DR

This paper explores the connection between dissipative dynamics and topologically massive gauge theories in pseudo-euclidean space, revealing analogies with damped harmonic oscillators and implications for condensed matter systems.

Contribution

It demonstrates that pseudo-euclidean Chern-Simons gauge theory in the infrared behaves like damped oscillators and links this to topologically massive electrodynamics and Bloch electron dynamics.

Findings

Infrared pseudo-euclidean Chern-Simons theory resembles damped oscillators.

Damped oscillators on hyperbolic plane are equivalent to undamped ones.

Equations match Lorentz force dynamics on charged particles in magnetic fields.

Abstract

In the pseudo-euclidean metrics Chern-Simons gauge theory in the infrared region is found to be associated with dissipative dynamics. In the infrared limit the Lagrangian of 2+1 dimensional pseudo-euclidean topologically massive electrodynamics has indeed the same form of the Lagrangian of the damped harmonic oscillator. On the hyperbolic plane a set of two damped harmonic oscillators, each other time-reversed, is shown to be equivalent to a single undamped harmonic oscillator. The equations for the damped oscillators are proven to be the same as the ones for the Lorentz force acting on two particles carrying opposite charge in a constant magnetic field and in the electric harmonic potential. This provides an immediate link with Chern-Simons-like dynamics of Bloch electrons in solids propagating along the lattice plane with hyperbolic energy surface. The symplectic structure of the reduced theory is finally discussed in the Dirac constrained canonical formalism.
