The Mass Hyperboloid as a Poisson-Lie Group
S. G. Rajeev, Patrizia Vitale
The light cone formalism of a massive scalar field has been shown by Dirac to have many advantages. But it is not manifestly Lorentz invariant. We will show that this is a feature…
Highly nonlinear wave solutions in a dual to the chiral model
S. G. Rajeev, Evan Ranken
We consider a two-dimensional scalar field theory with a nilpotent current algebra, which is dual to the Principal Chiral Model. The quantum theory is renormalizable and not asympt…
A Non-Riemannian Metric on Space-Time Emergent From Scalar Quantum Field Theory
Arnab Kar, S. G. Rajeev
We show that the two-point function σ(x,x')=\sqrt{<[ϕ(x)-ϕ(x')]^{2}>} of a scalar quantum field theory is a metric (i.e., a symmetric positive function satisfying the triangle ineq…
Scalar Quantum Field Theory on Fractals
Arnab Kar, S. G. Rajeev
We construct a family of measures for random fields based on the iterated subdivision of simple geometric shapes (triangles, squares, tetrahedrons) into a finite number of similar…
On The Relativistic Classical Motion of a Radiating Spinning Particle in a Magnetic Field
Arnab Kar, S. G. Rajeev
We propose classical equations of motion for a charged particle with magnetic moment, taking radiation reaction into account. This generalizes the Landau-Lifshitz equations for the…
Hamilton-Jacobi formalism for string gas thermodynamics
Anosh Joseph, S. G. Rajeev
We show that the thermodynamics of a system of strings at high energy densities under the ideal gas approximation has a formulation in terms of Hamilton-Jacobi theory. The two para…
