A Soluble Theory of Massless Scalar QED_2
F. T. Brandt, Ashok Das, J. Frenkel
In this brief report, we analyze a generalized theory of massless scalar QED_2 and show that, unlike the conventional scalar QED_2, it is free from infrared divergence problems. Th…
Retarded Greens Functions and Forward Scattering Amplitudes in Thermal Field Theory
F. T. Brandt, Ashok Das, J. Frenkel +1
In this paper, we give a simple diagrammatic identification of the unique combination of the causal n-point vertex functions in the real time formalism that would coincide with the…
The Self-Force of a Charged Particle in Classical Electrodynamics with a Cut-off
Josif Frenkel, R B Santos
We discuss, in the context of classical electrodynamics with a Lorentz invariant cut-off at short distances, the self-force acting on a point charged particle. It follows that the…
The Boltzmann Equation in Scalar Field Theory
F. T. Brandt, J. Frenkel, A. Guerra
We derive the classical transport equation, in scalar field theory with a V(phi) interaction, from the equation of motion for the quantum field. We obtain a very simple, but iterat…
