Analyzing Quasi-Photons in a Novel Field Theoretic Framework

EasyChair Preprint 15259

Abstract

This paper explores the concept of Quasi Photons within the framework of a specific model.
The model is defined in terms of a field theory with two sectors: one representing a harmonic
oscillator with negative norm and the other capturing the dynamics of a massless scalar field with a
negative mass squared in the subspace with negative norm. The analysis focuses on the construction
of field operators, their harmonic oscillator representation, and their corresponding path integral
formulation. The paper further investigates the real-space expressions for the propagator in the case
where the mass parameter is zero. Explicit expressions for the propagator and its various components
are derived, shedding light on the behavior of the system in both the positive and negative norm
sectors. The exploration emphasizes the implications of this unique model, providing insights into
the nature of quasi photons and their characteristics. The results presented in this paper contribute
to our understanding of unconventional quantum field theories and open up avenues for further
research into the intriguing properties of quasi photons.
